These Brazing alloys include general purpose brasses, brasses with addition of nickel, high temperature copper alloys and copper for furnace brazing. All these alloys are economical to use and can be generally supplied in variety of forms like rods, wires, preforms, Strips, powder and pastes. General purpose brasses can be used for brazing and for Oxy-Fuel Gas Braze-Welding process..
ALFA - 501 is used for brass brazing steels, malleable cast iron, copper, copper alloys with melting temperatures greater than 950 C, nickel and nickel alloys.It is also known as "Silicon Bronze".
ALFA - 502 is used for copper, malleable and cast iron brazing.
ALFA - 510 is often used for brazing tungsten carbide. It is also used with steel, nickel and nickel based alloys. This filler metal is unsuitable for protective atmosphere furnace brazing. It is also known as "Nickel Bronze".
ALFA- 510A is similar to ALFA510 but the presence of silver in it improves joint strength.
ALFA - 506 may be used on steels, nickel and nickel alloys. It is also known as "Phosphor Bronze".
ALFA - 5PC is generally used for brazing carbon and alloy steels, stainless steel, nickel and copper nickel. It is primarily used in furnace brazing with protective reducing atmospheres without flux.
