Product Details

Magnesium Welding Wire AZ91D 0.3~1.0 mm AZ31 AZ61 AZ80 ZK60

Magnesium alloy welding wire is made of high purity metallic magnesium into ribbons. Magnesium alloy has good corrosion resistance, electromagnetic shielding and radiation resistance, and can be recycled 100%. Magnesium alloys are alloys based on magnesium with other elements added.Its characteristics are: small density, high specific strength, large elastic modulus, good shock absorbency, impact load capacity than aluminum alloy, good corrosion resistance.The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium.The most widely used alloys are magnesium-aluminum alloys, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys.Good sag resistance: compared with other metals, magnesium alloys have higher deformation resistance, and the sag caused by impact is smaller than that of other metals.
