Magnesium Alloys
ER AZ61A
ER AZ61A The weldability of most magnesium alloys is good when proper filler metal in employed. A filler metal with a lower melting point and a wider freezing range than the base metal will provide good weldability and minimize weld cracking. AZ61A or AZ92A filler metals may be used to weld base metals of similar composition and also ZK21A base metal.
AZ61A filler metal is generally preferred for welding wrought base metals of those alloys because of lower cracking tendency. However, welds made in cast Mg-Al-Zn and AM100A base metals with AZ92A filler metal show less crack sensitivity. The weld metal will respond to the precipitation heat treatments normally applied to repaired castings. AZ101A filler metal may also be used to weld those cast base metals. EZ33A filler metal is used to weld wrought and cast base metals designed for elevated-temperature service; however, this filler metal should not be used for welding aluminum-bearing magnesium alloys because of severe weld cracking problems. When no other filler metal is available, most base metals may be welded with strips cut from the base metal.

QE22A
QE22A is a strong, silvery-white, light-weight metal that tarnishes slightly when exposed to air. QE22A alloy is a casting alloy having excellent tensile, fatigue and creep properties at elevated and room temperatures. It is weldable and pressure tight.
ZE41
ZE41 is a well proven magnesium casting alloy containing zinc, rare earths and zirconium. Used in the T5 condition, this medium strength magnesium alloy is ideal for high integrity castings operating at ambient temperatures or up to 300°F. In addition to displaying excellent casting characteristics, the alloy is both pressure tight and weldable.
ZE63-T6
ZE63-T6 is a magnesium sand casting alloy. Casting: Sand, Investment, Die and Permanent mold.
AZ31B
AZ31B is a wrought magnesium base alloy with good room-temperature strength and ductility combined with corrosion resistance and weldability. Increased strength is obtained by strain hardening with a subsequent partial anneal (H24 and H26 tempers).
AZ91A
AZ91A, B, C, D, and E have the same nominal composition but differ in ranges and/or specified impurity limits. The die cast alloy in as-cast condition (F) can be made for secondary metal, reducing the cost of the alloy. Must be used when maximum corrosion resistance is not required.
