ER5556 aluminum alloy welding wire rod

Introduction of ER5556 aluminum alloy welding wire rod
ER5556 aluminum alloy welding wire rod is aluminum-magnesium welding wire with higher than 5% magnesium and higher manganese content. It has high strength, good corrosion resistance and thermal crack resistance. The weld seam remains white after anodization, which can provide a good color matching for the welded joint.
