According to the processing method, aluminum alloy can be divided into deformed aluminum alloy and cast aluminum alloy. The numbers of aluminum and aluminum alloy are mainly divided into eight series.
Five series
5000 series aluminum rods belong to the more commonly used alloy aluminum plate series. The main element is magnesium, and the magnesium content is 3% to 5%. The 5000 series aluminum alloy represents the 5052, 5005, 5083, and 5A05 series. It can also be called aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than that of other series under the same area, and it is also widely used in conventional industries.
The most commonly used in mobile phones is 5052, which is the most representative alloy with medium strength. It has good corrosion resistance, weldability and formability, especially high fatigue strength and good seawater resistance. It is often used in products with high strength requirements. , but its coloring effect is less than ideal. It is suitable for sandblasting process, but not suitable for chemical sanding, matte surface, etc. It mainly uses casting molding and is not suitable for extrusion molding.
Six series
The 6000 series aluminum alloy represents 6061, which mainly contains magnesium and silicon. Therefore, it combines the advantages of the 4000 series and the 5000 series. 6061 is a cold-processed aluminum forged product suitable for applications requiring high corrosion resistance and oxidation resistance. Good workability, easy coating and good processability.
6061 and 6063 are commonly used in mobile phones. 6061 is stronger than 6063. It is cast and molded to form more complex structures. It can be used to make parts with buckles, such as battery covers, etc.
Seven series
Mainly containing zinc element, the 7000 series aluminum alloy represents 7075. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy. It is a heat-treatable alloy. It is a super-hard aluminum alloy and has good wear resistance. At present, we basically rely on imports, and our country's production technology still needs to be improved.
Eight series
The most commonly used 8000 series aluminum alloy is 8011, which belongs to other series. Most of them are used in aluminum foil and are less commonly used in the production of aluminum rods.
