Washington Alloy, TCU PBA 16, Filler Metal, Phos-Bronze A; 0.045 in, AWS A5.7 Class ERCuSn-A, 35,000 psi min.

Washington Alloy Phos-Bronze A filler metal is used for MIG and TIG welding of tin-bronze base metals such as 509 to 519 series, for brass and for overlay welding of steel. Phos-Bronze A contains approximately 5% tin and up to 0.35% phosphorus. The tin content increases the wear resistance of the weld deposit while the phosphorus acts as a deoxidizer. Preheating is recommended.
