Corrosion resistance

The aluminum alloy has the following characteristics: 1. It has good corrosion resistance to most corrosive substances under the two conditions of air oxidation and repair. ¢ÚIt has good resistance to pitting corrosion, void corrosion and intergranular corrosion. The higher content of Mo and Cr makes the aluminum alloy resistant to corrosion by chloride ion content, and the W element further improves the corrosion resistance.
