RBCuZn-A (Naval Bronze)
Alloy Type: A5.8, BRAZING Filler Metals
RBCuZn-A Naval Bronze (RBCuZn-A) is a copper-zinc brazing filler metal containing small amounts of tin to improve strength and corrosion resistance in the weld deposit. It is a good choice when the high strength properties of low fuming bronze are not required. A borax-boric acid flux is generally required when brazing with this product.
