The 5087 aluminum-magnesium alloy welding wire is specially designed for welding series alloys and for welding where the chemical composition of the filler alloy is close to that of the base metal. Aluminum alloy welding wire has good corrosion resistance and color matching after anodizing. 5087 magnesium-aluminum alloy welding wire is aluminum-magnesium welding wire with higher than 5% magnesium and higher manganese content. It has a higher height, good corrosion resistance and thermal crack resistance. The weld seam is white after anodizing, which can provide a good color matching for the welded joint. This series of aluminum welding wires are used for high-magnesium aluminum alloy argon arc welding filler materials.


Aluminum-magnesium alloy welding wire use: 5087 aluminum-magnesium alloy welding wire is used in bicycles, aluminum scooters and other sports equipment, locomotive carriages, chemical pressure vessels, ordnance production, shipbuilding, aviation, etc.
Aluminum welding wire containing about 5% magnesium has high strength, good corrosion resistance, and good color matching after anodization. It is recommended for welding cast and forged aluminum alloys with 5% magnesium and 5000 series, and some 6000 series and 7000 series deformed aluminum alloys, such as 5050, 5052, 5083, 5456, 6005A, 6061, 6063, 6082, 7005, etc.
