Name:Aluminum Alloy Welding Wire welding Rods ER4043


ER4043 is a kind of aluminum & silicon alloy welding wires with 5% silicon, also name S331, and this product is of good liquidity, good forgeability, but lack of ductility. Due to the high silicon content, when used in the welding of high magnesium alloy, easily generated in the weld brittle Mg2Si, reduce the plasticity and the corrosion resistance of joint. In addition, the welding surface color dark, anodized after more different with parent metal color.

Welding wire used to weld ship building steel(A,B,D,E,A36,D36,E36)and equivalent mild steel or 550Mpa grade mild alloy steel, such as container building, construction machine, railway construction, pressure vessel for semi-auto or automatic gas shielded welding wire.

Top Features

  • Welding Filler Wire
  • Spray and Flame Metallizing Wire
  • Similar to AlSi12 (Germany), BS N21 (United Kingdom)
  • Lower melting point and higher fluidity than 4043 wires
  • Can be used as a substitute for 4043 wires to increase silicon in the weld metal, minimize hot cracking and produce higher fillet weld shear strength
  • widely used for brazing of aluminum, Al-Mn, Al-Si-Mg alloy materials
