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 strip, wire, powder, paste, preforms, clad trimetal products and flux-cored wire..
ALFA - 311A is used for brazing of precisions silver linings of chemical equipments or precision silver equipment.
ALFA - 308A is used in assembling of vacuum tubes where volatile elements are not permitted to be used. This alloy is free flowing yet it does not wet well on ferrous metals.
ALFA - 312 is generally used for joining sterling silver or brazing of objects made of silver alloys which are enameled after the brazing process.
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 - 307B is used especially for joining sterling silver. The colour, after brazing , approximates the colour of sterling silver .
ALFA - 313 is used for brazing of silver goods which are made from silver alloys.
ALFA - 311B is similar to ALFA-307B but is more economical and provides less strength to the joint.
ALFA - 307A is particularly suitable for joining electrical components requiring high electrical conductivity.
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-305A is similar to ALFA-309. It is used where better gap filling is required.
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-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.
ALFA-301is suitable for brazing ferrous and non ferrous metals not damaged by temperatures required. It is also useful for brazing copper
ALFA - 311SnA is suitable for protective atmosphere brazing and is of particular advantage when the precipitation-hardening heat treatment is combined with the brazing operation.
ALFA - 306SnB is similar to ALFA-313.
ALFA - 306Sn is similar to ALFA 309B in its applications . The tin contents help in wetting the surface of stainless steel, carbon steel and nickel base alloys. It is specially used for vacuum applications.
ALFA - 311Sn is a low melting filler metal and does not contain cadmium. It is ideal for furnace brazing. It is used by the dairy and food industry where cadmium free joints are required. This brazing alloy is less prone to cause stress cracking on stainless steel and some nickel alloys. After brazing it gives a closer match with whitish metals such as stainless steel.
ALFA - 310Sn may be used on any nickel and nickel alloys, copper and copper alloys and steels.
ALFA - 310SnA is advantageous where zinc volatilization is objectionable in furnace operations because of absence of Zinc in its composition.
ALFA-309Sn is a low temperature cadmium free alloy with free flowing characteristics.
ALFA-304Sn is a free flowing alloy for ferrous, non ferrous and dissimilar joints.
ALFA-311SnB is free flowing cadmium free filler metal used with ferrous and non ferrous base metals.
ALFA-307Sn is used for assembly of copper tubes in the refrigeration industry and on equipments and containers in the food industry. Presence of tin improves its fluidity and it has good wetting properties.
ALFA-303Sn is a free flowing alloy for ferrous, non ferrous and dissimilar metals with good fluidity.
ALFA-307SnA is economical filler metal and is useful on ferrous and non ferrous joints which do not require impact strength or high ductility.
ALFA-302 is used in brazing operations where brazing and heat treatment of steels is simultaneously done.
ALFA-303A is used for torch brazing on carbon and stainless steel, copper, nickel and its alloys. It is used in boiler works for drawn components.
ALFA-305B is used for brazing nichrome resistance elements.
