Manufacturer and Exporter of Quality Brazing and Welding products that include Silver Brazing Alloys, Silver Copper Phosphorous Brazing Alloys, Copper Based Brazing Alloys, Aluminum Wires, Brazing Fluxes, S.S. Tig and Mig Wire. Our Products   SILVER BRAZING ALLOYS   Cadmium Bearing Alloys   Cadmium Free Alloys   For Tungsten Carbide Tipped Tools SILVER COPPER PHOSPHORUS BRAZING ALLOYS COPPER BASED BRAZING ALLOYS (BRASS) FLUXES     News & Events We have been able to carve a niche for ourselves in the international market by supplying products including brazing alloys and brazing fluxes like silver brazing fluxes, copper brazing fluxes and other soldering fluxes that are known for their reliability and quality. Our range of products has a proven track record in many industries across the globe including Air Conditioning, Defence, Heavy Engineering and Power, Hydraulic Motors, Pumps, Radiators, Railways, Refrigeration, Switch Gears and Tools Industries.         For Tungsten Carbide Tipped Tools We manufacture excellent range of brazing filler metals containing nickel specifically for the tungsten carbide tipped tools industry because of its need of protection from crevice corrosion and higher temperature service properties. These alloys are available in forms of wire, foils or shims.  Product Code Composition % Melting Range Corresponding Standard   Ag Cu Zn Cd Others Celsius DIN 8513 BS 1845 AWS A5.8.89 IS 2927 -409 63 28.5 - - 2.5Ni6Sn 691-802 - - B Ag-21 -   ALFA-409 is used in brazing AISI/300 and 400 series stainless steels, as well as the precipitation-hardening nickel and steel alloys. It is particularly suited to protective atmosphere furnace brazing because of the absence of zinc and cadmium. The nickel content makes it immune to crevice corrosion, particularly on 400 series stainless steel by imparting a nickel rich layer along the fillet edge. It is used for brazing stainless steel vanes of gas turbine aircraft engines. -410 55 40 4 - 1Ni 718-857 - - B Ag-13 BA Cu Ag 8B   ALFA-410 is used for service temperature up to 370°C . Its low zinc content makes it suitable for furnace brazing. -405A 50 20 27 - 2Ni 660-750 - - B Ag-24 -   ALFA-405A is low melting, free flowing, cadmium free and suitable for use in joining low carbon 300 series stainless steels (particularly food handling equipment and hospital utensils) and small tungsten carbide inserts for cutting tools. -405 50 15.5 15.5 16 3Ni 632-688 - - B Ag-3 BA Cu Ag 12   ALFA-405 is particularly suitable for brazing carbide tool tips to tool shanks as it wets the carbide tool tip very satisfactorily. It has a wide wetting range, therefore, the solid and liquid portions do not tend to separate excessively. It is good filler metal for bridging gap. It has good corrosion resistant properties and is particularly suitable for brazing stainless steels also. -411 56 42 - - 2Ni 771-893 - - B Ag-13a -   ALFA-411 is similar to ALFA-410, except that it contains no zinc, which is advantageous where volatilization is objectionable in furnace brazing. -404 40 30 28 - 2Ni 671-775 - - B Ag-4 BA Cu Ag 18   ALFA-404 is used for brazing carbide tip brazing. Similar to ALFA-405, but higher brazing temperature is required. It flows freely and does not contain cadmium. -404A 40 30 25 - 5Ni 660-860 - - - -   ALFA - 404A is used for brazing of tungsten carbide and stainless steels.     Home   |   About Us   |   Products   |   Infrastructure   |   Contact Us   |   Enquiry   |   Mail Us   |   ISO Certification
