Preferred Base Metals
|
Suitable for welding and overlaying series of forging and casting Aluminium Alloys(＞7%Si)of Al- Si - Mg -Cu, Al-Si, Al-Si-Mg:
AlSi12、AlSi12(Cu)、AlSi10Mg(Cu)、AlSi10Mg、AlSi9Mg and so on

|
The characteristics
|
Such welding wire, which contains 12% silicon and has good corrosion resistance , can be used for welding variety of forging and casting or extruded aluminum alloys. The advantages of lower melting point and higher fluidity avoid the distortion of metal alloy after welding．It shows ash black after anodizing.
