MATRIX SF – Cu.Mn.13AI.7

Application areas

The alloy MATRIX SF-Cu.Mn.13AI.7 is a welding wire containing manganese, nickel, aluminium and bronze. This is suitable for joining or fixing cast metals and for welding basis metals with similar compositions. Other applications include and surface applications on CMn steels and cast iron, which require bronze diffusion bonding. Coatings with this alloy allow a very high corrosion, erosion and cavitation resistance. Excellent in marine, power and chemical plants for the production of propellers, pumps and seawater devices.
