AMPCO-TRODE® 300

AMPCO-TRODE® 300

Description and Application

AMPCO-TRODE® 300 aluminum bronze bare filler rod is available for use with the gas tungsten arc welding process. The weld deposit has the highest yield strength and hardness (nominal 300 Brinell) of the AMPCO-TRODE® series. In addition to high hardness, the deposit also has excellent bearing and wear-resistance qualities.

These characteristics make this deposit adaptable for use in extreme bearing applications where very high pressures are encountered.

These characteristics – hardness, bearing properties and wear resistance all combine to make AMPCO-TRODE® 300 ideal for surfacing iron and copper-base materials. Dies overlaid with AMPCO-TRODE® 300 have surprising freedom from scratching and galling; die marks are almost completely eliminated.
