Characteristics and advantages of several magnesium alloys


Magnesium alloy AZ91D

Magnesium alloy AZ91D is mainly rely on the pressure mold casting auxiliary, is characterized by high strength and corrosion resistance than pure magnesium greatly improved, mainly used for electrical products shell, small size thin or shaped bracket.

Concept

AZ91D belongs to the cast magnesium alloy category, mainly rely on the pressure mold casting auxiliary processing after processing, can use electrophoresis and other surface ways to change the appearance. It is characterized by high specific strength and corrosion resistance, which is greatly improved compared with pure magnesium. It is mainly used for the housing of electrical products, small-size thin or special-shaped brackets, etc. A represents metal aluminum Al,Z represents metal zinc Zn,9 represents aluminum content of 9%,1 represents zinc content of 1%, and the last D is the identification code.
