We can supply the Phosphor copper brazing ringwith BCuP-2 in competetive price and precise size .

Phos/copper brazing welding, whose jiont has high strength(generally greater than 180 Mpa)  suit  for  brazing copper and copper alloys with low plasticity,and unfit to be used in the  impacted or curved state .Phos/copper filler metal has the self-brazing ability,  so can braze copper and silver without flux or braze copper alloy mixed with flux 102. Especially, its fit with the brazing with torch, induction and resistance.

The phosphor included in phos/copper alloy, together with iron, can produce brittleness compound, so this alloy can't be used to braze steel or other ferrous metals.

The joint or socket connection with 0.05-0.13m/n gap is recommended ,and it will get a satisfying effect.

AWS Standard	Use expertise
BCuP-1	It is the highest temperature of the P,Cu solder,widely used in Gas appliances
	and welding with BCuP-2.
BCuP-2	Good flow property,economical,widely used in the brazing of  presentting in
	air-conditioners and the no-vibratim load areas
BCuP-3	Have certain plasticity ,suitable for brazing copper alloy and  some copper ,
	which can't conjugate tightly
BCuP-4	It is of low melting point,It is especially fit for the automatic braze welding ,it
	has been largely applied in the soldering with four-way valve and cut-off valve
BCuP-5	Bettered plasticity and conductivity of joint,suitable especially for brazing
	copper and copper alloy with vibration load
BCuP-6	Widely used in brazing copper and copper alloy in the fields of air-conditioning and
	mechanical-electrical good flow property and filling capability
