AMPCO-TRODE® 150
AWS A5.7 – ERCUAL-A3
Description and Application
AMPCO-TRODE® 150 aluminum bronze spooled wire and bare filler rod produce a deposit of high strength and good ductility with a nominal hardness of 166 Brinell as applied with the inert-gas processes.
AMPCO-TRODE® 150 is recommended for welding AMPCO® 18 alloy. It is ideal for piston overlay applications and bearing surfaces requiring high strength and good ductility.
Price range: $166.00 through $564.00
