Are magnesium alloys corrosion-resistant?
Corrosion resistance of a magnesium alloy part depends on environmental conditions and on the chemical composition, thermal and mechanical history and surface condition of the part. In some environments, contact with parts made from dissimilar metals can lead to severe damage of the magnesium part due to galvanic corrosion. Magnesium alloys, when properly made and applied, are corrosion resistant and are used successfully in a wide variety of applications. The corrosion that is encountered usually is a result of improper design or application. Q: What is alloy ASTM AG40A and what is it used for? This is a pressure die cast zinc alloy. The chemical analysis is available. The mechanical properties are available. It is primarily used in the automotive industry for both under bonnet and decorative functions. Found the answer you need?
