ER4047 aluminium welding wire

L400ER4047 aluminum silicon solder

Standard :GB/T13815 BAL88Si AWS A5.1 ER4047

ER4047 aluminum welding wire with 12% silicon alloy, suitable for welding all kinds of cast and extruded aluminum alloy. Low melting point and good fluidity make welding deformation of base metal very small. The performance characteristics of

This product is 12% silicon alloy welding wire, melting point about 500℃ and higher fluidity can also be used as welding material. Can replace ER4043, higher silicon content, help to reduce hot cracks and produce higher fillet shear force. Suitable for welding all kinds of cast and extruded aluminum alloy. Low melting point and good fluidity make welding deformation of base metal very small. Chemical composition
