More Information
Summary:The invention discloses a magnesium alloy which comprises (by weight ratio) Al 6.5-7.5%, Mn 0.2-0.7%, Zn 0.4-1.0%, Si<=0.1%, Cu <=0.05%, Ni <=0.001%, Fe<=0.004%, and balancing Mg, the magnesium alloy has a average tensile strength of 280 MPa, yield strength 136 MPa, percentage of elongation 9%, compared with AZ30A magnesium alloy, because the percentage of elongation is increased substantially, the technical requirement for forging automobile wheel hubs can be met.
