Magnesium alloy bars

Magnesium Alloy Grades

Magnesium alloy bars are available in various grades, each offering distinct properties suitable for specific applications:

• AZ31B: Mg-3%Al-1%Zn. Known for good strength, excellent formability, and weldability.
• AZ61A: Mg-6%Al-1%Zn. Offers higher strength and better corrosion resistance than AZ31B.
• AZ80A: Mg-8%Al-0.5%Zn. High strength and good corrosion resistance.
• AZ91D: Mg-9%Al-1%Zn. High strength and excellent castability.
• ZK60A: Mg-6%Zn-0.5%Zr. High strength and good fatigue resistance.
• WE43: Mg-Y-RE (Yttrium, Rare Earth). Exceptional strength-to-weight ratio and high-temperature performance.

These grades are manufactured in various tempers, such as F (as fabricated), O (annealed), and T5 (artificially aged), adhering to standards like ASTM B107/B107M-13.
