Characteristics
ER4047 is a eutectic aluminum-silicon welding wire containing 12% silicon. Compared with 4043, it has a lower melting point and a finer solidification range. It has high silicon content, good fluidity, and minimization of hot cracking tendency and increases the shear strength of the weld. The anodized color is gray black.
Typical Applications
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.
