AZ31B AZ91D ZK61M Magnesium And Magnesium Alloy Series 1, Products: Magnesium alloys have a low density (about 1.8 g/cm³) and high strength. They are the lightest metallic structural materials, with a density that is two - thirds that of aluminum and one - fourth that of iron. Magnesium alloys have a high specific strength and can be used as high - strength materials. The specific strength of high - strength magnesium alloys can even be comparable to that of titanium. Magnesium alloys have a large elastic modulus and good shock absorption properties. Within the elastic range, when subjected to impact loads, magnesium alloys can absorb half as much more energy as aluminum alloy components. Therefore, magnesium alloys have excellent seismic and noise reduction performance. In addition, magnesium alloys also feature high thermal and electrical conductivity, non - magnetism, good shielding properties, and non - toxicity. 2, Application Areas: Materials for Aerospace, Automotive and New Energy, Tool and Die - making, and Semiconductor Fields Unique Advantages | Main Applications | Execution Standards |
