Phos-Copper Brazing alloys
DESCRIPTION:Phos-Copper brazing alloys's main materials are copper and phosphorus,it has the characters of easily-flowing, low cost, and perfect welding effect.Needn't to use flux when brazing copper and silver objects, the joints have good strength.
Alloy	Corresponding Alloy	Chemical Composition			Melting Range		Main Features	Typical Application
		P%	Sn%	Cu%	Solidus°C	Liquidus°C
JCuP -1	201 BCu92P TC-310D	7.5 -8.5	­	The balance	710	780	Close to eutectic crystal composition, low melting point, easy flow, can flow into a small clearance of brazing seam.	Use for copper and copper alloy parts, refrigeration compressor, not suitable for brazing attacking shocking bend parts
JCuP -2	BCu93P    Bcup-2 TC-310A	6.5 -7.5	­	The balance	710	800	Contain a little phosphorus, has better plastic nature, a little higher melting point.	Use for copper and copper alloy parts, suitable for air conditioning, refrigerator, evaporator, heat exchanger and water heater ect.
JCuP -3	202	6.1 -6.8	­	The balance	710	820	Contain a little phosphorus, good plastic nature, a little higher melting point.	Can make many kinds of brazing ring, wires, brazing copper and copper and copper alloy parts, brazing ample clearance tie-in.
JCuP -3Sn	BCu88PAg Degussa86	6.5 -7.5	6.5 - 7.5	The balance	640	680	Good spread ability, good caulking ability.	Use for many kinds of copper and copper alloy.
JCuP -5Sn	BCu86SnP	4.8 -5.8	7.0 - 8.0	The balance	620	670	Low melting point, easy flow.	Use for copper or brass parts of water heater, radiant heating, radiant heating ect.
JCuP   -6Sn	208	5-6	5-6	The balance	650	800	Low melting point, easy flow.	Use for copper or brass parts of water heater, radiant heating, radiant heating ect. brazing ample clearance tie-in.
