Compared with cast magnesium alloys, AZ31B wrought magnesium alloy has higher strength and better plasticity, making it suitable for thin sheets, extrusions, and forgings. Adding AL and ZN elements to pure magnesium can improve the mechanical and processing properties of AZ31B magnesium alloy.

AZ31B magnesium alloy composition

AZ31B magnesium alloy is known for its excellent forgeability and superior plasticity. Compared to AM60B magnesium alloy, AZ31B is commonly used in engine gearboxes, oil pumps, and oil pipes due to its functional advantages. The following chart outlines the composition of AZ31B magnesium alloy, providing valuable information for your specific needs.

Magnesium AZ31B mechanical & processing properties

Within a certain range, the AZ31B magnesium alloy's tensile strength increases with the AL (or ZN) content. When the AL and ZN content is around 3% (by mass), the elongation of the AZ31B magnesium alloy reaches its highest value. And, when the AL and ZN content exceeds 3% (by mass), the β phase is easily precipitated in the casting structure, which reduces the processing properties of AZ31B.
