ER 4047

ER4047 is the eutectic aluminum silicon alloy welding wire with about12% Si element. Suitable for Al-Si, Al-Si-Mg, Al Si mg Cu wrought aluminium and aluminium (7%Si) argon arc welding. Low melting point and good fluidity to base the welding deformation is small, the more

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
