Copper To Copper Phos Copper Alloy Bcup2 Welding Suppliers Phosphorus Copper Square Brazing Copper Rod

Classification and composition:

1 . BCu92P: composition P: 7.5-8.5%, copper: margin.The melting temperature is 710-750℃, the melting point is low, the flux is good, but more brittle, generally used for brazing shock load, vibration free copper and brass parts welding

2. BCu89SnP : component P: 6.80-7.50%, tin: 5.0-6.0%, copper: margin.The melting temperature is 620-660℃. The solder has a low melting point and good fluidity. It can braze copper, brass, bronze and low zinc brass parts with silver brazing agent .

3.Our regular size of copper phosphorus brazing rods are length 450mm , 500mm and diameter are 1.3mm , 2.0mm , 2.5mm, 3mm , 4mm and 5mm . In addition, we also support special customization according to your need .


1. Copper brazing ring just need some sample cost, we will return it back when proceed into mass production.

2. Support for free custom unconventional sizes

4. In order to reduce the loss of silver welding rods during transportation, we use a plastic tube per kilogram to increase protection. Besides, we provide also shipment by air, by sea, by truck, or any other shipping methods according to customer's demand.


Copper-Phosphorus/Copper-Phosphorus-Silver Brazing Filler Metal

Copper-Phosphorus brazing alloy is easy flow,low cost and has good processing property and self-braze ability. It applies to contact brazing,gas flame brazing,induction brazing and furnace brazing,the joint has high tensile strength and good electrical conductivity. Copper-Phosphorus-Silver brazing alloy can reduce the melting points,in can improve both alloy is plasticity and wet ability, as well as the alloy is strength and toughness.

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 O 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.
