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 (
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
