AZ91D Properties | Magnesium Alloy AZ91D | Dynacast
2019/12/23· Alloy AZ91D is the most widely used magnesium die cast alloy and has an excellent coination of mechanical properties, corrosion resistance, and castability. Corrosion resistance is achieved by enforcing very strict limits on three metallic impurities—iron, copper and nickel.
Alloys - Zinc Die Casting
Alloy 2 offers the highest strength and hardness of the conventional zinc alloys. The high copper content (3%) in No. 2 results in property changes upon long-term aging. These changes include slight dimensional growth, lower elongation and reduced impact performance (to levels similar to aluminum alloys) for die cast products.
