At that time, the widely used materials for aluminum alloy frames were 7075 and 6063.

The 7 series aluminum alloy mainly uses zinc as the main alloy, with a composition ratio of 6%. The 6 series aluminum alloys mainly use magnesium and silicon as the main alloys, and the total composition ratio is low.

In terms of strength, 7075 is stronger, but only slightly stronger. As can be seen from the table, the yield strength (the strength that allows aluminum to permanently bend and deform) is only slightly stronger than 6063.

All aluminum alloys used as frame materials have passed heat treatment T6.

But overall, 6063 is a better material. Since 7075 contains a high proportion of other metals, it is difficult to weld and dispose of. Especially 7075 (the last two numbers represent the alloy content) has a higher proportion, so it is usually not a material that can be used as a frame.

In contrast, because 6063 contains a lower proportion of other metals, it can increase its strength and reduce its wind resistance through special shapes and various treatments. It can even be piped three times to reduce it. weight.

1. It can be divided into the following categories according to its use:

1. Aluminum profiles for doors and windows used in the construction of doors and windows (divided into two types: doors, windows and curtain walls).

2. Special radiator aluminum profile for CPU radiator.

3. The difference between aluminum alloy shelves and aluminum profiles lies in the different cross-sectional shapes. But they are all produced by hot melt kneading.

4. Industrial aluminum profiles: mainly used for automated machinery and equipment, the skeleton of enclosures, and for companies to customize mold openings based on their own machinery and equipment needs, such as assembly line conveyor belts, elevators, dispensing machines, and testing Equipment, etc., mostly used in the electronic machinery industry and clean rooms!

2. Classification by alloy composition:

Can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and other alloy brand aluminum profiles, among which 6 series is the most common. The difference between different brands is that the proportions of various metal components are different. In addition to commonly used door and window aluminum profiles such as 60 series, 70 series, 80 series, 90 series, Except for architectural aluminum profiles such as curtain wall series, there are no clear types of industrial aluminum profiles. Most manufacturers process them according to customers' actual drawings.

3. Classification according to surface treatment requirements:

1. Anodized aluminum

2. Electrophoretic coating aluminum

3 . Powder-coated aluminum

4. Wood grain transfer aluminum

5. Planed aluminum (divided into two types: mechanical planing and chemical polishing)
