Product description

ER4047 is the eutectic aluminum silicon alloy welding wire with about 12% Si element. Suitable for Al-Si, Al-Si-Mg, Al Si mg Cu wrought aluminium and aluminium (7%Si) argon arc welding.

WIRE COMPOSITION (%)

Key Features:

1.Welding filler.

2.Metal spraying.

3.Similar to AlSi12 (Germany), BS N21 (United Kingdom).

4.Lower melting point and higher fluidity than 4043 wires.

5.Widely used for brazing of aluminum, Al-Mn, Al-Si-Mg alloy materials.

6.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.

Application:

  • Automotive components
  • Body panels
  • Brazing of aluminum sheets, extrusions, and castings
