Brazing Alloys

Brazing is a metal-joining process whereby a filler metal is heated above melting point and distributed between two or more close-fitting parts by capillary action. The filler metal is brought slightly above its melting temperature while protected by a suitable atmosphere, usually a flux. It then flows over the base metal (known as wetting) and is then cooled to join the work pieces together. It is similar to soldering, except the temperatures used to melt the filler metal are higher.

Uses

Brazing is the leading method of metal joining in many HVAC (Heating, Ventilation, Air Conditioning) appliances and equipment. It is also commonly used in joining or repairing copper pipes. As a general rule, brazing is used when solid, leak proof joints must be made without melting the base metals

Automotive industry uses brazing extensively, especially for brazing aluminum radiators, which use tube-to-fin and tube-to-header joints.

Brazing is also used in pipe and tube applications to extend length, fabricate shapes, join dissimilar materials, and to ensure a water or pressure tight joint. Common base metals include aluminum and its alloy, copper and alloy, steel and stainless steel.

Brazing applications extend to microwave reflectors, satellites, cameras, and other sophisticated instrumentation. Common base metals used include oxygen free copper, nickel, stainless steel, copper- nickel alloy, iron-nickel-cobalt alloys, and tungsten.

Our Ranges

Tubular Brazing Wires:
Seamless Tubular wire for manual as well as automatic brazing without additional use of flux. Made according to a new technology.
Aluminium Brazing Wire:
Used for joining aluminium and aluminium alloys. The wire consist of an aluminium alloy with silicon. It is ductile, malleable and conducts both heat and electricity well. A non-corrosive flux made from aluminium and potassium fluorides is used.
Zinc Brazing Wires:
Used for soldering aluminium, stainless steels and other alloys. Made from seamless tubes of zinc aluminium alloy filled with non-corrosive flux, a product from the FP Soudage range, called ALUNOX NCS, made from aluminium and caesium fluroides.
Silver Brazing Wires:
Silver Brazing Alloys are easy to use, possess high strength impact with short melting ranges, free flowing and versatile. They have outstanding flow characteristics and mechanical properties. These are available in forms of wire, foils or shims, preformed wires or strips, granules, rings and paste or powder. Besides, these can be customised as per clients specifications and applications.
Used for manual & automatic silver-brazing and silver braze-welding. It is used most frequently for steel and copper piping in combustible gas installations, and reparation or maintenance work.
