Brazing Wire Copper Phos Welding Wire Rods For Brazing Copper Alloys
Phos Copper Brazing Alloy welding rod
For copper-copper and copper-brass applications
Details of Phos Copper Brazing Alloy welding rod:
1) P: 6.6-7.4%, Cu: Balance
2) Form: wire, rod, spool, flat, square, rings
The solder is suitable for A/C and refrigeration industry,tube industry.
P-Cu brazing alloys is widely used in refrigerating field,which with good flow property and low melting point.The cheap price is good to automatically brazing.
Copper phosphorus brazing filler metal is with 7% phosphorus brazing material,it is with good flow property because of the high phosphorus containing.It is suitable for filling large gap,widely applied on electric power and electronic machine fields.
(1) The heating temperature of the brazing process is relatively low, so the deformation of the weldment after brazing is small. At the same time, the influence on the microstructure and properties of the base metal of the weldment is relatively small.
(2) Brazing alloys with low melting points have good 'wettabilty,' high strength and toughness
(3) Ramp rate should be as quick as possible while brazing
(4) Joints become bright gray, returning to original copper color once dipped into a 10% sulfuric solution

Q1: Is it safe to drink the water or product once these are in place?
A1: The manufacturer Qixing Welding Material indicates that the 0 Silver Phos Copper Brazing Rod would be safe for use on copper water lines but is probably not the best way to to it. The cost of the O phos rod is considerably more than standard no lead solder.Also when brazing with the phos the inside of the copper line will develop an black powdery coating which would have to be flushed out of the lines or the line would require a purge while brazing to prevent the black coating from forming.. As said before "not the best way to do water lines"
Q2: Is the rod suitable for refrigeration line sets?
A2: Qixing welding material products advises that the bcup-2 is a low cost alloy suitable for most copper to copper or brass joints where good fit-up exists, and the assemblies are not subject to excessive vibration or movement. If there is good joint fit up where the clearance between the connections are between .002 and .007 then the will work fine. We does not recommend using this product on compressors or motors where vibrations can exist.
Q3: Can Phos copper Brazing rod be used on galvanized steel and other metals?
No the Phos Copper Brazing Rod is design to be used on copper and copper alloys only, If you want to weld steel , our brazing product of silver welding rod can meet your requirements.
