Washington Alloy Silicon Bronze 3/32 TIG Welding Wire 1# TM SB/05

Washington Alloy® Silicon Bronze 3/32 Diameter ERCuSi-A TIG Welding Wire 1 lb. Mini Pack TM-SB/05

1 lb. tube 36 inch lengths - Washington Alloy® 3/32 diameter Silicon Bronze TIG welding wire is a copper-based alloy containing about 3% silicon and may have small percentages of manganese, tin, and zinc. It is typically used for the TIG welding of copper, brass, bronze, steel, galvanized steels and also cast iron.

Preheat: When working with silicon bronze base metal, keep the interpass temperature below 150° F to minimize hot cracking. Base metals of cast iron may need a preheat of 600° F while copper may need a 400-800° F. The use of a small narrow weld puddle will reduce the contraction stresses and give you a faster cooling during the hot-short temperature range.

Shielding Gas:

Argon 100%
