Aluminum welding rod should actually be aluminum wire, aluminum content ≥ 99.5%, still less than 0.5 % of other ingredients. Aluminum welding wire er1100 Features: aluminum wire , Welding Wires Manufacturer content ≥ 99.5%, has excellent corrosion resistance, very High thermal and electrical conductivity , and excellent processability . On anodized The material is ideal when required color is recommended for welding 1000 series aluminum alloys. Typical Chemical Composition : si ≤ 0.03, cu ≤ 0.002, zn ≤ 0.013, fe ≤ 0.18 , Mn ≤ 0.003, al margin widely used in railway locomotives , power, chemical , food Products and other industries .
