Silver Brazing Alloys Without Cadmium

Silver Brazing Alloys Without Cadmium

We have developed a range of cadmium free alloys keeping in view the requirements of our end users, which mainly consist of food and beverage industry. These alloys are suitable for use on most ferrous and non-ferrous materials. We offer numerous material compositions for general purpose and specialty applications which are available in rods, strip, wire, powder, paste, preforms, clad tri-metal products and flux-cored wire and rods.

ALFA 309B is suitable for furnace brazing in a protective atmosphere. It is very fluid and can be used on copper or copper alloys, stainless steel, nickel based alloys and carbon steel.
ALFA - 306 is used for brazing monel, silver and nickel alloys.
ALFA - 305 may be used where the use of brazing alloy containing cadmium as for food handling or process equipment is objectionable. It is also used in electrical industry. Due to broad melting range it is a better filler metal for filling wide joint clearances or forming large fillets.
ALFA-309 is a general purpose brazing alloy for use at higher brazing temperatures. It is an excellent filler metal for brazing brass parts.
ALFA-308A is popular cadmium free filler metal particularly for brazing in "Traction Motors"
ALFA-307 is similar to ALFA-309. It is also used for brazing of ferrous and non ferrous metals.
ALFA-304 has a wide melting range and used in brazing of copper based alloys, monel, nickel and mild steel.
ALFA-308 is a filler metal with intermediate temperature for use in brazing of ferrous and non ferrous metals.
ALFA-303 has moderate ductility which limits the joint design and application. It has good wetting characteristics and is free flowing.
ALFA-307C is an economical filler metal used for brazing ferrous metals, stainless steel, copper and brass. It is used in mechanical, electrical, refrigeration industries and for brazing musical instruments.
