Aluminum 2A12(Al-Cu-Mg ) is the hard alloy, its composition is more reasonable and owns better overall performance. It is the largest amount of hard aluminum. The alloy is characterized by: High strength, with a certain degree of heat resistance, can be used as working parts below 150°C.
It has excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness and no deformation after processing, compact material without defects and easy polishing, easy color film, excellent oxidation effect, etc.
The corrosion resistance is not high, in order to improve the corrosion resistance of anodic oxidation treatment and often used methods of paint or aluminum surface layer.
Widely used as space fixtures, electrical fixtures, communications, automation machinery parts, precision processing, mold manufacturing, electronics and precision instrument, SMT, PC board solder vehicles and so on.
