MATRIX SF – Cu.AI.9Fe

Application areas

This weld metal is a bronze-aluminium one that is generally used for joining aluminium-bronze or similar compositions, for manganese, silicium, bronze and some copper-nickel alloys. The SAFRA alloy SF-Cu AI.9Fe is suitable for welding parts which can undergo seawater corrosion. It is also used for joining dissimilar alloys, as for example copper and steel, cast iron, bronze and for wide range of coating applications. Excellent for metal spraying.
