Harris Products Group, 03SIB90, Welding Alloy, Silicon Bronze, All Position, For Steel to Copper, 1.02 lb

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

• Silicon bronze base metals generally do not require pre-heat
• Used to weld galvanized steels
• All position welding
• Use 100% Argon for shielding gas
• Marked with model number on each end for easy identification after use
• Brass or copper base metals may require some pre-heat depending on copper content and thickness
• Frequently used for TIG (GTAW) "braze-welding" of coated sheet steels
• Silicon bronze alloy for welding base metals of steels and cast iron to copper, brass and bronze
