Postalloy® 94-SPL

Postalloy® 94-SPL is a gas-shielded, high strength bronze welding wire offering outstanding joining properties when used on different base materials. Deposits are extremely tough. Base metals recommendations are bronze, carbon and alloy steels and cast iron.

Frictional wear and corrosion resistance - Deposits work-harden in service and take on an exceptionally high polish providing excellent bearing properties. In addition the corrosion resistance is among the best of the copper alloys with good resistance to salt water and other chemicals.
