Aluminum and aluminum alloy welding wires can be divided into aluminum-magnesium, aluminum-silicon and pure aluminum welding wires. Characterized by excellent anti-corrosion capacity and relatively high joint strength, aluminum-magnesium welding wires can be applied to fields such as ship heavy industry, cryogenic vessels, power plants, railway construction, etc.; with excellent fluidity and permeability, silicon-containing aluminum alloy is suitable for the connection of hard aluminum, castings and forged alloys.
It can be used for industries such as shipbuilding, automobile manufacturing, food, repair and maintenance, etc.; welds produced by pure aluminum consumables are ductile and can be stretched or hammered without breaking. So pure aluminum consumables can be applied to industries such as chemicals, food, electronics, repair and maintenance.
