AMPCO-CORE® 200 is an aluminum bronze flux core wire for use with the Gas Metal Arc Welding process.

AMPCO-CORE® 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.

Equivalent Materials

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.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
