Product Description

Aluminum Welding wire ER4047

DIN EN ISO 18273
SAL 4047(AlSi 12 (A) )
Performance Performance&Usage
ER4047 is a type of aluminium alloys wires containing 12% silicon, low melting point, good liquidity, good corrosion resistance, the color is ash black after anodic process.
ER4047 aluminium & silicon is with high of crack resistance, but low plasticity, so for Plastic deformation joints after welding, we donor suggest it. You should strictly clean the oxide film on the edge of the workpiece and oil before welding. Otherwise it will make bad weld produce and cause porosity, slag inclusion and other defects. Also you can use a plate to hold molten metal to ensure meld form.
The argon arc welding of Al-Si, Al-Mg-Si, AI-Mg-Si-Cu Forging aluminium and aluminium(7%Si) is used as the filler material, And it has advantages of low melting point and good fluidity which avoids the distortion after welding. Widely used in pure aluminium, Al-Mn, Al-Si-Mg alloys melding.
