Magnesium alloy Welding Wire AZ31 Mg Al Alloy mig welding wire
Magnesium alloy welding wire is use in all kinds of forging Mg alloy and cast Mg alloy,
such as: optical instrument, aerospace, automobile spare parts, magnesium products for civil use, and handiwork welding.
ADVANTAGE
· small density, lighter than Al, higher specific strength
· higher fatigue limit,
· bigger impact load than Al
· better thermal conductivity
· good casting property
· dimensionally stable
· easy revocery
· subsititute for engineering plastics
· high corrosion resistance
