Common Questions on Magnesium Alloy Specifications
Q: What is the aluminum (Al) and manganese (Mn) content for AZ91D magnesium alloy under ASTM standards?
A: According to the ASTM standard table, AZ91D magnesium alloy contains 8.5-9.5% Aluminum (Al) and 0.17-0.40% Manganese (Mn).
It also includes 0.45-0.9% Zinc (Zn) and very low levels of impurities such as Iron (Fe) and Copper (Cu).
Q: Which magnesium alloy grade provides the highest tensile strength among the listed types?
A: Based on the mechanical properties table, AS41A offers the highest tensile strength range of 230-260 MPa. In comparison, AZ91D provides a tensile strength of 200-250 MPa.
Q: How do the elongation properties differ between AM60B and AM20 magnesium alloys?
A: The data shows that AM20 has superior ductility with an elongation of 8-12%, whereas AM60B features an elongation of 4-8%.
Lower aluminum content in AM20 contributes to its higher elongation compared to AM60B and AM50A.
