Techniweld Silicon Bronze Tig Welding Rod, 3/32″ x 36″
Known as ERCuSi-A.
An excellent choice for joining plain or galvanized sheet metal as well as other coated steels.
Surfacing area subject to erosion.
Joining copper, copper-silicon and copper-zincs to themselves or steel.
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.
Keep the weld pool small to promote fast solidification and minimize cracking.
A high Boric acid brazing flux is required for Oxy-Acetylene brazing.
