Description

AMPCO-CORE® 300 is an aluminum bronze flux core wire for use with the Gas Metal Arc Welding process.

AMPCO-CORE® 300 is primarily an overlay filler metal. In addition to high hardness, the deposit also has excellent bearing and wear-resistant qualities.

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

This material data has been provided by AMPCO METAL.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.

Other

AMPCO-CORE® 300 is available from stock in two diameters: 0.045” (1.2mm) and 0,062” (1.6mm). Both sizes are available in 12″ (300mm) spools weighing 33lb (15 kg) each. Other diameters are available upon request.

Processing methods

Welding position and deposits: The flat welding position is recommended. Backhand (trailing) welding is preferred rather than forehand (pushing) to make either stringer or weaved beads.

Shielding gas: 100% Argon
