Copper Phosphorus Brazing Alloys

Aluminium Filler Wires

Our copper brazing alloys offer a range of self fluxing alloys for brazing copper in air. We have developed copper brazing alloys, which can be used in refrigeration plant and equipment, water heaters, calorifiers, electric elements, motors and transformers etc. However, we also offer customised solutions as per the client's application and specifications. These copper brazing alloys are available in wires and rods, strips, wire flattening, wire preforms, strip preforms, granules and spheres.

- 101A	-	95	5		-	710-924	-	-	BCup-1	BA Cu P1
- 101A	Brazing Filler Metal is particularly suitable resistance brazing applications. This filler metal is more ductile & less fluid at brazing temperature than other filler metals containing more phosphorous.

- 101	-	93	7		-	705-800	L-CuP8	-	BCuP-2	BA Cu P2
- 101	Brazing alloy is extremely fluid at the brazing temperature. It will penetrate joints with very little clearance.

- 101B	0.5	93	6.5		-	650-810	-	-	-	-
- 101B	Similar to ALFA102, but contains less silver.

- 102	2	91.5	6.5		-	645-740	-	-	BCup-6	BA Cu P3
- 102	Brazing alloy has high fluidity. It has ability to fill gaps at the lower end of its brazing range & is very fluid at high end.

- 105	5	89	6		-	643-807	L-Ag5P	CP 1	BCuP-3	BA Cu P4
- 105	Brazing filler metal may be used where very close fits cannot be held. It is best used with the lower joint clearance. It is majorly used in Air conditioning & Refrigeration industry.

- 105A	5	88	7		-	643-771	-	-	BCup-7	-
- 105A	Brazing alloys is more fluid than ALFA105A & has a lower liquidous temperature. It is extensively used in heat exchanger & tubing joints.

- 106	6	87	7		-	650-740	-	-	BCup-4	-
- 106	It is extremely fluid at brazing temperature. Provides more strength to joint than ALFA105.
