Silicon bronze tig welding rod-ercusi-a - .045" - 1LB.
High-Performance Silicon Bronze TIG Welding Rod. ERCuSi-A TIG
welding rod. AWS: A5.27 grade. Class: ERCuSi-A.
ERCuSi-A SILICON BRONZE AWS A 5.27 CLASS ERCuSi-A
ERCuSi-A Silicon Bronze is primarily used for TIG, Plasma and Oxy-
Acetylene welding or brazing on Steel and Copper Alloys. A chemical
analysis of Copper and Zinc as well as alloying elements of 3% Silicon and
small amounts of Tin and Manganese produce welds with excellent
mechanical properties. High strength, ductile and sound welds are easily
attained by using a neutral or slightly oxidizing flame (especially on Copper
Alloys.) Keep the weld pool small to promote fast solidification and
minimize cracking. A high Boric acid brazing flux is required for Oxy-
Acetylene brazing. Silicon Bronze is ideal for plain and zinc coated thin Steel
sheet metal. Proper procedures will produce tensile strengths of 50,000 psi.
