ERCuSn-A Phos Bronze A is a copper-zinc bronze containing approximately 5% tin and up to 0.35% phosphorus added as a deoxidizer used to weld bronze and brass. It can also be used to weld copper if the presence of tin in the weld metal is not objectionable.
Typical Applications: overlaying of steel; joining of 509-519 series tin-bronze base metals
