BCu-3 is an oxygen free, high conductivity copper used for braze joining of ferrous metals, nickel based alloys and copper-nickel alloys. It is also used in thermal spray and arc spray metallizing applications.

RBCuZn-A is a copper-zinc brazing filler metal that contains tin for improved strength when used on copper and copper alloys. It is also used for braze welding of nickel, nickel alloys, steel and stainless steel.

RBCuZn-B is a copper-zinc brazing filler metal similar to RBCuZn-A, but has additions of iron and manganese for increased hardness and strength. The addition of nickel is to make certain the iron is evenly dispersed in the deposit.

RBCuZn-B is used to braze weld cast iron, copper, copper alloys, nickel, nickel alloys, steel, and stainless steel.

RBCuZn-C is a copper-zinc brazing filler metal similar to RBCuZn-B, but without the addition of nickel. Low Fuming Bronze is a popular brazing alloy for copper, copper alloys, nickel, nickel alloys, steel, and stainless steel. It is also used in thermal spray and arc spray metallizing applications.

RBCuZn-D is a high nickel copper-zinc brazing filler metal that is most often used for brazing tungsten carbide, but it is also used to braze weld cast iron and steel due to a better color match over the yellow brasses.
