Since the reform and opening up, China’s aluminum profile industry has been developing vigorously. As an important application material in the construction and machinery industry, my country has become the world’s largest aluminum profile production base and consumer market.
As we all know, as a downstream processing product of the aluminum industry chain, aluminum profiles are mainly purchased from aluminum rods and electrolytic aluminum. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. The production process is also constantly being improved. , Is a kind of metal raw materials widely used in modern industries.
The “Development Plan for Non-ferrous Metals Industry (2016-2020)” compiled and issued by the Ministry of Industry and Information Technology pointed out that the main line of China’s non-ferrous metals development in the next five years is “structural reform and expansion of market demand.” From the perspective of the “13th Five-Year” development plan in the automotive manufacturing, rail transit, and aerospace industries closely related to the aluminum industry, aluminum is the non-ferrous metal that has the most conditions to expand market demand, and it also provides high-end aluminum companies with A good opportunity for development.
The aluminum profile can be divided into 1-9 series through the different composition content of aluminum and the different proportion of the added alloy composition:
1xxx series represents: 1050, 1060, 1070, 1000 series aluminum plates are also called pure aluminum plates. Among all series, the 1000 series is the series with the most aluminum content, and the purity can reach more than 99.00%.
2xxx series representatives: 2A16 (LY16), 2A12 (LY12), 2A06 (LY6), with higher hardness, with the highest content of copper, which is about 3-5%. 2000 series aluminum plates are aviation aluminum materials, which are not often used in conventional industries.
3xxx series representatives: 3003, 3003, and 3A21 are the main ones. It can also be called anti-rust aluminum plate. The production technology of 3000 series aluminum plate in my country is relatively excellent. The 3000 series aluminum plate is made of manganese as the main component, and the content is between 1.0-1.5.
4xxx series represent: 4A01, 4000 series aluminum plates, which belong to the series with higher silicon content. Usually the silicon content is between 4.5-6.0%. It belongs to construction materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance.
5xxx series representatives: 5052, 5005, 5083, 5A05 series. In my country, the 5000 series aluminum sheet is one of the more mature aluminum sheet series.
The 6xxx series represents: 6061, which mainly contains two elements of magnesium and silicon. Therefore, the advantages of the 4000 series and the 5000 series are concentrated. It is a cold-treated aluminum forging product, which is easy to coat, high in strength, and strong in corrosion resistance. The 6xxx series is currently the most frequently used product on the market.
The 7xxx series represents: 7075, which mainly contains zinc. It also belongs to the aerospace series. It is an aluminum-magnesium-zinc-copper alloy and a heat-treatable alloy. It is often used to manufacture aircraft structures, requiring high-strength structural parts and mold manufacturing with high strength and corrosion resistance.
The more commonly used 8xxx series is 8011, which belongs to other series. Most of the aluminum plates whose main function is to make bottle caps are also used in radiators, and most of them are aluminum foil, which is less used.
The 9xxx series is a spare series, and the International Aluminum Strip Federation specifically stated that in order to cope with the emergence of aluminum plates containing other alloying elements.

The newly extruded aluminum profile, because the aluminum surface is easily oxidized by oxygen in the air, affects the service life and aesthetics. Therefore, we need to perform surface treatment on the newly extruded industrial aluminum profile.
Commonly used surface treatment methods for industrial aluminum profiles include anodic oxidation and electrophoresis, but, in addition to these two, there are several surface treatments for industrial aluminum profiles, which are unified for everyone:
1. Electroplating-Electroplating is also a very common surface treatment method, not only aluminum profiles but also various other metals can be electroplated. Electroplating is to plate a metal protective layer on the metal surface. Sometimes it needs to be polished and then electroplated.
2. Sandblasting-the industrial aluminum profile sandblasting process can not only get a matte effect but also the fine emery on the metal surface can eliminate the extrusion lines on the surface of the industrial aluminum profile. This is a way to kill two birds with one stone. The thickness of sand determines the effect of sandblasting.
3. Brush-similar to the car pattern, the wire drawing process makes the surface of the industrial aluminum profile form a smooth straight line, which is very beautiful and atmospheric.
4. Car pattern-use a lathe to process a regular pattern on the surface of the aluminum profile. The difference from the rubbing pattern is that the car pattern is a ring pattern, and the rubbing pattern is a straight pattern.
5. Polishing-Polishing can remove burrs on the surface of industrial aluminum profiles, and make the surface bright, which can achieve a mirror effect.

The commonly used aluminum alloy profiles in China are 6-series aluminum profiles, which 6063, 6061, and 6005 series are used the most in 6-series.
So what is the difference between these three grades of aluminum alloy? Now we have to conduct an in-depth study on it.
The 6-series aluminum alloy are all aluminum-magnesium-silicon alloys, which have the characteristics of good forming performance, good corrosion resistance and high hardness.
Therefore, they are all suitable for making good use of profiles, but they each have different uses.
Different alloy composition content:
Among them,
The magnesium content of 6005 is 0.4%~0.6%, and the silicon content is 0.6%~0.9%. The magnesium content of 6061 is 0.8% to 1.2% and a silicon content of 0.4% to 0.8%.
The magnesium content of 6063 is 0.45%~0.9%, and the silicon content is 0.2%~0.6%.
The content of other trace elements is different, so the content of the alloy will cause the difference in performance, strength, and scope of use.
The plastic properties of 6063 aluminum are better than 6061, so most of the extruded profiles use 6063 grades. However, the strength and processing properties of 6063 are not as good as 6061 aluminum. Compared with 6061 and 6063, 6005 aluminum has higher tensile strength and yield strength, and has better fracture toughness. For profiles requiring higher strength, 6005 brand will be used.
The surface gloss of 6063 and 6061 is better than that of 6005, and 6005 aluminum will be darker. Therefore, 6063 aluminum is more suitable as a decorative material
6061 and 6005 can be made into aluminum plates, but 6063 basically cannot be made into aluminum plates.
6063 aluminum alloy is a kind of aluminum alloy material with extremely strong comprehensive performance, which is widely used in the fields of I industry and construction. 6061 aluminum is mainly used in aerospace, marine equipment, molds, electronic products, corrosion-resistant structures and other fields. 6005 aluminum alloy is often used in structures that require high strength such as ladders and TV antennas.
In addition to the 6 series aluminum alloy profiles, the 7 series also have extruded profiles. The 7 series has higher strength than the 6 series, and the plasticity is not as good as the 6 series, so the production is more difficult and the price is more expensive. The 7 series aluminum profile is mainly used in the aerospace field, also called aviation aluminum profile. We often see so-called “aviation aluminum profiles” in our market, but they are actually 6 series aluminum profiles. Real aerospace aluminum profiles will not be used in the civil market.

Mechanical lines on the surface of industrial aluminum profiles are one of the main reasons for aluminum profile processing waste, and it is also a difficult problem in the aluminum processing industry.
G profile
The quality of aluminum rod
The grains of the aluminum rod are coarse, and the surface of the extruded aluminum profile will form a coarse crystal band during extrusion production. The light reflection will form a pattern of light and dark on the surface of the profile.
Aluminum rod inclusions or segregation, and the segregation Al9Fe2Si2 on the surface of the aluminum rod will also cause the surface texture of the extruded aluminum profile. In addition, the high hardness inclusions in the aluminum rod will scratch the die when the aluminum profile is extruded, and cause stripes on the surface of the extruded industrial aluminum profile.
Extrusion process
The squeeze ratio is unreasonable
Excessive extrusion ratio will squeeze the die. If the extrusion ratio is too small, the deformation of some parts of the aluminum profile will be within the range of the critical deformation. When the aluminum alloy is recrystallized, large grains will appear in the critical deformation. , Aggravate mechanical lines.
Extrusion temperature
The extrusion temperature will increase as the extrusion speed increases, and the high temperature will cause mechanical lines and even cracks.
Extrusion speed
Excessively high extrusion speed will tear the surface of the aluminum profile.
Extrusion die
At present, most of the domestic 6063 grades of industrial aluminum profiles adopt the method of forward extrusion. When the aluminum cast rod passes through the mold under the conditions of high temperature and pressure, it is easy to cause aluminum to stick to the mold. As a result, the aluminum profile may be adhesive, tear, and strained.
Mold material
Die steels of different grades will have different resistance to metal adhesion. At present, H13 steel is the best die steel material.
Mold surface treatment method
The adhesion and wear of aluminum alloy occur on the contact surface of the mold and the aluminum material, so the contact surface of the mold should be nitridated, which can effectively improve the hardness, wear resistance and fatigue strength of the contact surface of the mold.
The nature and state of the mold sizing belt
The nature and condition of the die surface sizing belt have a very large impact on the surface roughness of extruded aluminum products.
Mold structure
The structure of the die bridge and the height of the welding chamber have a relatively large impact on the formation of mechanical lines on the surface of industrial aluminum profiles.

Question, then what are the advantages of all-aluminum furniture worth our purchase?
Green, healthy and environmentally friendly, zero formaldehyde
Compared with panel furniture frequently exposed to excessive formaldehyde, all-aluminum furniture does not have to worry about formaldehyde. This is because aluminum alloy cold-rolled steel plates and other metal materials are obtained from a series of processing from our mineral resources. Moreover, in the production of all-aluminum furniture, almost all accessories are made of metal materials, and no adhesives such as glue are used, which is truly environmentally friendly.
Fashionable and beautiful, delicate and diverse shapes
At present, most of the colors of all-aluminum furniture are wood grain series, and the color treatment is delicate and delicate and very realistic. The all-aluminum furniture is the same as the panel furniture, and it also has the design of top line, Roman column, European side panel, etc., and can be flexibly shaped.
Waterproof, fireproof, mildew proof,
Compared with our panel furniture and solid wood furniture, this all-aluminum furniture has the characteristics of waterproof, fireproof and mildew proof. Therefore, the second advantage of all-aluminum furniture is that it can withstand the test of fire and reduce losses. It also has moisture-proof effect, which is very suitable for families in southern my country. Because the metal property of aluminum is relatively stable, all-aluminum furniture is fireproof and waterproof, and can withstand direct burning without damage, or it can be washed directly with water without decay.
Easy to clean and take care of.
The surface of all-aluminum furniture is smooth and delicate. Compared with panel and solid wood furniture, it is impermeable and has a unique advantage in moisture-proof and waterproof. The bathroom is made of all-aluminum furniture, which is not only waterproof, moisture-proof and easy to clean, but also gives a clean, bright and refreshing feeling, and can extend the service life of the furniture. Statistics from the 2017 “All-Aluminum Smart Home Forum” show that the service life of traditional wooden furniture is 8 to 12 years. Facts have proved that the first is damage. After the furniture enters the home, it will corrode to a certain degree and cause damage such as moist and moth. The need to replace the furniture is even more costly. The second is cleaning and maintenance. Compared with design inspiration, consumers are more concerned about the state of furniture after entering the home. It is easy to clean, easy to maintain, and does not require time and effort. All-aluminum furniture is the best choice.
Moisture-proof and insect-proof
There is no need to worry about the hazards of insect infestation and damp at home. It must be an urgent need for homeowners. Many expensive pinewood and mahogany furniture were destroyed by insects. It is worth mentioning that the moisture-proof characteristics of all-aluminum furniture are very suitable for use in the electronic age. Many of our precious audiovisual tapes and classic CDs are most afraid of being interfered by strong magnetic fields. If you use all-aluminum furniture, it will be very A good solution to such problems.
Antibacterial and no odor
The newly renovated new house has a major fatal hazard-pollution and odor. The pungent chemical material smell brought by the decoration of the new home is difficult to remove for a while. No matter how much air freshener is used, the peculiar smell still disturbs your private space for a long time. The problem is that such peculiar smell always endangers the health of you and your family. Song Guangsheng, director of the Environmental Monitoring Center of the China Interior Decoration Association, introduced that indoor pollution, mainly four types of pollutants, formaldehyde, benzene, ammonia and radioactive substances, is currently contained in a variety of man-made panels, adhesives, and wallpaper. The main material of all-aluminum furniture is aluminum alloy, which avoids the peculiar smell of traditional wood and artificial panels.
Firm and durable, strong bearing capacity
The hardness of diamond is 10, and the hardness of aluminum alloy is also 10. Aluminum alloy was originally selected for the series of doors, windows and curtain walls. Its strength, hardness, thickness, density, and waterproof and moisture-proof are obvious to all! Then it was transferred to furniture products. No matter the performance and service life, they have undergone repeated experiments and tests, and they are strong and durable.
Value preservation can be recycled
Have you ever seen the furniture that will be recycled? All-aluminum furniture is! Traditional household products start to depreciate the moment consumers buy home, and finally replace and discard. From the perspective of consumer groups, the current market is paying more and more attention to product life cycle and value preservation. Shop around, choosing the best is the market way, so the advantages of high-quality products are undoubtedly revealed. On the macro level, sustainable development, recycling, energy conservation and environmental protection are becoming more and more important. All-aluminum furniture can maintain value and recycle, and consume low consumption; it also extends a helping hand in energy saving and environmental protection, and protects the natural environment.
