AMPCO-TRODE® 200
AWS A5.7 – RCUAL-C
AMPCO-TRODE® 200 aluminum bronze bare filler rod is available for use with the gas tungsten arc welding process. The weld deposit has a nominal hardness of 269 Brinell and has high strength.
AMPCO-TRODE® 200 is primarily an overlay filler metal. The high strength values of the deposit combined with excellent wear-resisting characteristics make this alloy unsurpassed for bearing overlays where extreme wear and high pressures are encountered in service.
