AMPCO-TRODE® 8N
DIN 1733: – SG-CuAl8Ni2-W.Nr 2.0922
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 |
