Description

AMPCO-TRODE® 7 is an iron-free, aluminum bronze alloy available in spooled wire and 36″ (1000 mm) bare-filler metal rod for use with the gas metal-arc and gas tungsten arc welding processes respectively.


AMPCO-TRODE® 7 deposits are used primarily to overlay bearing and wear-resistant surfaces requiring hardness of approximately 125 BHN and to resist corrosion especially from saltwater, metal salts and many commonly used acids in varying concentrations and temperatures.


This alloy is not recommended for joining since the deposit does have a tendency to be hot short.
