Copper Based Brazing Alloys (Brasses & 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 and pastes.
Aluminium Filler Wires
Aluminium Filler Wires
Backed by our sound expertise in the specific industry, we are presenting wide gamut of aluminium filler wires that are developed in compliance with international standards of quality using industry grade raw material. Our Aluminium product range can be put for many applications by adding one or.
Fluxes
Fluxes
We manufacture a wide range of fluxes, which can be put to varied uses. Fluxes consist of mild organic acid or strong inorganic acid which promotes high speed cleaning of metals with strong surface oxides and are generally used for silver brazing, copper brazing, solder and aluminum.
BRAZING - The Process

BRAZING - The Process

Brazing Flux is a mixture of chemicals that is used to prevent the formation of oxides and other undesirable substances in molten brazing filler metal and on solid base metal surfaces. By removing the surface oxides brazing flux reduces surface tension and promotes the free flow of brazing filler metal.
