Description
Washington Alloy® Silicon Bronze 3/32 Diameter ERCuSi-A TIG Welding Wire 10# Box TCU SB/05
10 lb. box 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 below150° F to minimize hot cracking. Base metals of cast iron may need a preheat of 600° F while coppermay need a 400-800° F. The use of a small narrow weld puddle will reduce the contraction stresses andgive you a faster cooling during the hot-short temperature range.
