Locomotive Copper Phosphorus Solder , Frame Copper Brazing Alloy
Xinxiang Qixing Welding Material Co., Ltd, started in the
1980’s,our company is located in the middle of China, factory area
is 30,000 square meters, including more than 9,000 square meters
We are the most professional producer on welding materials. As the
member of China Welding Association, we focus on brazing materials
development and production, dedicated to create the most excellent
brand of welding material in the world.
We mainly produce “Qixing” brand of copper-based, sliver-based,
aluminum-based brazing materials, and all of our products meet SGS
and RoHS directive requirements.
Now our production capacity is 450tons/month for brazing rod, and
for Phos-Copper alloys, that is about 220tons/month . In our field,
now we are the No.1 in China.
With excellent quality and service, currently we take more than 90%
marketing shares in Chinese after-sales service market, and
cooperate with many famous companies, such as Midea, Gree, LG,
Hisense, Haier, Aux and so on; we also export our products to
Middle East, Southeast Asia, Central Asia, Europe, North America
and other regions and countries.
We always promise" best quality, best service”! Keep strive to
make”QIXING”brand brazing materials to be the most welcomed
products in China and all over the world!
Phos-copper brazing alloy is base on the raw material with the
binary alloy of copper-phosphorus. It has good fluidity, low cost,
perfect processing property. No need to add flux when brazing
copper and silver, and the joint has good strength.
Phos-copper brazing alloys filler metal has high activity and high
fluidity and can flow over a larger area, showing perfect
performance in contact brazing, oxy-acetylene brazing, induction
brazing and furnace brazing. The joint strength is higher and the
conductivity is better. A flux is required while brazing brass to

Phosphorus-copper welding rod is red copper containing phosphorus.
Due to its good self-decontamination ability and good fluidity and
wettability, it has been made into "silver-free welding rod"
instead of silver welding rod for the welding of copper and copper
pipe joints in the refrigeration system of air conditioners,
freezers and refrigerators. Suitable for oxy-acetylene, TIG, MIG
welding, widely used in automobile, ship, electrical and other
Q : Can phosphorous copper brazing rod be used for stainless steel?
A : No, the main component of stainless steel is iron. When iron
and copper are together, iron is more likely to lose electrons,
making it easy to rust, which is a damage to iron !
Q : What is the difference between a brass alloy welding wire and a
phosphor copper brazing filler metal ? What are they used for ?
A ; Brass brazing sticks is a copper containing phosphorus. Because
of its good self-decontamination ability and good fluidity and
wettability, it has been used only as a "silver-free electrode"
instead of silver brazing welding rods for brazing of air
conditioners and refrigerators.
Q :What are the advantages of phosphor copper welding rod?
A : Phosphor copper welding wire is a low-cost welding alloy, which
can be used in copper and copper welding with no strict
requirements on welding temperature and controllable device.
