Copper Based Brazing Alloys-Brasses And Bronzes

Copper Based Brazing Alloys-Brasses And Bronzes

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 & 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 -503 is used to join steels, copper, copper alloys, nickel, nickel - base alloys and stainless steel. It is used with torch, furnace and induction brazing process. It is called "Super Brass".
ALFA -504 is used to join steels, copper, copper alloys, nickel, nickel - base alloys and stainless steel where corrosion resistance is not important .
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".
