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.

• The quality of aluminum rod

1. 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.
2. 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

1. The squeeze ratio is unreasonable
2. 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.
3. 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

1. Die steels of different grades will have different resistance to metal adhesion. At present, H13 steel is the best die steel material.

2. 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.

3. 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.

4. 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.

The best use of partitions is to divide the office space perfectly, make better use of the space, and meet basic office purposes.

The glass partition is a top-to-top partition that can completely divide the space. The professional high partition can not only realized the traditional space separation function, but also is significantly better than the traditional partition wall in terms of lighting, sound insulation, fire prevention, environmental protection, and easy installation.

Advantages of aluminum alloy glass partition

1. It can be partially disassembled and reused for many times, which greatly reduces the cost of frequent office relocation. Some of the materials of the compartment system will not bring waste to the environment and are a kind of green building materials.
2. The installation of aluminum alloy glass partition is faster than ordinary partition wall.
3. The internal structure of aluminum alloy glass partition allows easy cable laying. It does not need to be buried in the wall, the maintenance and replacement of the cable are more convenient, the strong and the weak electricity are separated, and the cable trough can play a shielding role for the signal line.
4. Aluminum alloy glass partition is fire-resistant and fire-resistant. The partition system is entirely composed of metal structures. Glass, aluminum alloy and other materials are also fire-resistant.
5. Aluminum alloy glass partition has good sound insulation effect, and the partition wall has very good sound insulation effect, and no pollution and odor emission, and can be used immediately after installation.
