AMPCO-TRODE® 8N

AMPCO-TRODE® 8N

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.

Typical Applications

Ship propellers, Bearing overlays, Pumps,
Chemical industry, Breaker blocks, Guide grooves
