Harris Products Group, 03SIBH0, Welding Alloy, Silicon Bronze, 1.02 lb, TIG (GTAW)

Silicon-bronze TIG (GTAW) welding alloy is used to weld similar composition base metals of steel and cast iron to copper, brass and bronze. Frequently used to "braze-weld" coated sheet steels. It can also be used to weld on galvanized steels. Conforms to AWS A5.7.

Features

• Brass or copper base metals may require some pre-heat depending on copper content and thickness
• Marked with model number on each end for easy identification after use
• Used to weld galvanized steels
• All position welding
