Description and Application
AMPCO-TRODE® 8N aluminum bronze spooled wire and bare filler rod produce a deposit of high strength and good ductility with a nominal hardness of 140 Brinell as applied with the inert-gas processes. The addition of nickel improves corrosion resistance in heat and saltwater.
AMPCO-TRODE® 8N is especially suited for marine environments, joining, and cladding components undergoing metal to metal wear. It is ideal for ship propellers, shipbuilding, pumps, shafts and guide grooves.
