Wholesale High Quality Phosphor Copper Brazing Rods from China Suppliers - Reliable Factory Direct Products Suppliers, Factories
Copper brazing alloy is a specialized material designed for brazing applications on copper substrates. These alloys typically feature a low melting point, allowing them to melt and fill joint gaps efficiently without compromising the integrity of the copper substrate. This process results in a robust metallurgical bond with the copper surface. As a leading supplier in China, our factory produces high-quality copper brazing alloys that meet rigorous industry standards, ensuring reliability and performance for all your brazing needs. Choose our copper brazing alloys for durable and effective metal joining solutions
Good fluidity during welding, can flow into small spaces.
② Moderate melting point
Good fluidity during welding, perfect performance under gas flame, induction and furnace brazing methods, outstanding oxidation resistance at high temperature, excellent corrosion resistance and fatigue resistance after welding, suitable for high temperature and high pressure environment.
③ Good joint strength and conductivity
It can quickly transfer heat and achieve precise temperature control, ensuring stable and efficient welding process, perfect for MAPP, MAP, propane and oxygen acetylene gas welding gun settings.
④ No need to use brazing flux
When brazing copper with copper-phosphorus brazing alloy, the phosphorus in the brazing alloy plays the role of brazing flux.
Application Scope
A popular and economical solution for HVAC, plumbing and mechanical repairs, used for brazing of copper and copper alloys in motor, instrumentation and refrigeration industries, very suitable for gas welding, contact welding and some furnace welding, suitable for brazing copper to copper, brass and bronze joints in air conditioners, freezers, evaporators, heat exchangers, water heaters, etc.

Frequently Asked Questions
What are the primary materials of your copper brazing alloys?
Our copper brazing alloys are primarily composed of Copper (Cu) and Phosphorus (P), ensuring excellent electrical conductivity, thermal performance, and joint strength.
Do I need to use flux during the copper brazing process?
No extra brazing flux is required when brazing copper to copper. The phosphorus content in our copper-phosphorus brazing alloy acts as an effective self-fluxing agent. However, a flux is recommended when joining brass or bronze.
What are the main application scopes for these brazing rods?
They are widely used in HVAC, plumbing, refrigeration, and electrical industries. They are highly suitable for joining copper, brass, and bronze components in air conditioners, evaporators, heat exchangers, and water heaters.
What standard sizes do you offer, and do you accept custom orders?
We offer flat, square, and round shapes in various dimensions (such as 1.3x3.2mm, 3.2x3.2mm, and diameters from 1.5mm to 3.0mm with 500mm length). Yes, other custom sizes can be manufactured based on specific customer requirements.
How are the products packaged for standard export shipment?
We use standard export seaworthy packaging, which includes wrapping the alloys in polyethylene film with a drier to prevent oxidation, placed inside carton boxes. Standard packages are 5.67kg/PVC bag (11.34kg/carton) or 5kg/PVC bag (10kg/carton).
