Aluminum Bronze

(High Mn )

Best for the overlay welding of iron-casting and non-alloy steel that especially need corrosion resistance.Also good for overlay welding of cast Iron and Non-alloy low alloy steel that requires corrosion resisitance.

Aluminum Bronze

(High Ni)

Particularly suitable for welding casting and forging products of Cu-Al-Ni material such as propellers,bearing weights,valves,pumps and pipe systerms. Very good corrosion resisitance to seawater.

Aluminum (Ni) Bronze

Recommended for the joining and overlaying of copper-aluminum alloys,aluminum coated steel in machinery and chemical industry as well as for Iron welding in shipbuilding.Also excellent for the join welding of brass tube and copper-aluminum that requires resisitance to erosion.

ERCuAl-A3
