What are the three major categories of aluminum disc wholesale?

　　Aluminum disc wholesale is to add various alloy elements (the main alloy elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloy elements are nickel, iron, titanium, chromium, lithium, etc.) during the processing of aluminum plates to improve the mechanical properties and chemical indicators of aluminum plates. Aluminum disc wholesale has some special properties that pure aluminum plates do not have, and is widely used in special environments, such as ships, refrigerators, molds, aerospace equipment, etc.

　　Three major categories of aluminum disc wholesale

　　1. Aluminum disc wholesale can be divided into 2××× series aluminum copper aluminum disc wholesale (Al--Cu), 3××× series aluminum manganese aluminum disc wholesale (Al--Mn), 4××× series aluminum silicon aluminum disc wholesale (Al--Si), 5××× series aluminum magnesium aluminum disc wholesale (Al--Mg), 6××× series aluminum magnesium silicon aluminum disc wholesale (AL--Mg--Si), 7××× series aluminum zinc aluminum disc wholesale [AL--Zn--Mg--(Cu)].

　　2. Aluminum disc wholesale can be divided into binary aluminum disc wholesale, ternary aluminum disc wholesale, quaternary aluminum disc wholesale and multi-element aluminum disc wholesale according to element units.

　　3. Aluminum disc wholesale can be divided into heat-treatable aluminum disc wholesale and non-heat-treatable aluminum disc wholesale according to whether it can be strengthened by heat treatment. Non-strengthening aluminum disc wholesale can only be strengthened by cold processing, but not significantly strengthened by heat treatment.
