Welding or brazing with copper phosphorus welding rods is the main purpose of these special rods. Mostly, they are composed of copper alloys which contain phosphorous as a deoxidizing agent. Phosphor copper solder happens to be a binary alloy of copper and phosphorus, used for soldering purposes. It has good fluidity and is adaptable to contact brazing, flame brazing, high frequency brazing and furnace brazing. The inclusion of silver into the phosphor bronze alloy increases its solder wettability significantly, raises it strength as well as toughness and reduces its melting point. It has wide applications in industrial refrigeration as well as motor manufacturing industries, electrical equipment manufacture industries and instrument manufacturing industries amongst others. Flame method, resistance method and high-frequency technique are the major ones applied while using copper zinc solders. For more information on these materials and their applications consider consulting a China copper phosphorus welding brazing rod Manufacturer.

Soldering is made smoother and more uniform by the phosphorus content which increases fluidity of the solder.
Phosphorus works as a deoxidizing agent in flux-free solders.
This drop in temperature supports an easier copper alloy processing, reducing also the energy requirement for brazing.
One can be sure that there are strong bonds that will form once the material is properly wetted before joining them.
This gives robust joints in welded or brazed assemblies.
Brazing methods to choose from include contact, flame, high-frequency, and furnace brazing among others.
It also has good corrosion resistance properties.
These electrodes are less expensive than using pure silver or any other costly metallic alloys.
Phosphorus copper solder has a wide range of applications and is commonly used in ordinary flame welding. It is mainly used in the refrigeration, air conditioning, plumbing and electrical industries. We can produce all kinds of formulas, and can also cooperate with R&D and customization to reduce costs and increase efficiency for your production. Specifically Please contact the technical department if required.
These rods are widely used in the refrigeration industry, motor manufacturing, electrical appliances, instruments, and various other manufacturing industries.
Copper phosphorus welding brazing rods are suitable for contact brazing, flame brazing, high frequency brazing, and furnace brazing.
Compared with pure silver or other high-cost alloy electrodes, they are generally more cost-effective, balancing performance and cost.
The phosphorus content acts as a deoxidizer, reducing the need for additional flux during the brazing process, simplifying the procedure and reducing costs.
Phosphorus enhances fluidity, lowers the melting point, acts as a deoxidizer, and improves the wettability of the solder.
