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
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.

and copper alloys.|
Q1: Is it safe to drink the water or product once these are in
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.
