China [CN] Flux cored brazing ring is a kind of self flux material rolled by flux cored brazing wire/rod. The cored flux is carefully selected to match the filler metal with high activity, non-corrosion, no moisture absorption. This perfect combination of flux and filler metal can simplify and eliminate a separate fluxing operation, thus profoundly improves the efficiency of brazing process.It is widely used in pipe brazing of refrigerator, air conditioning, radiator, automobile parts and tools, etc.
The function of flux in the flux cored brazing ring is required to maintain high activity, non-corrosion, no moisture absorption for expiration duration of one year. The uncertainty of the diameter of this product is strictly controlled to 0.1 mm so that the ring has high consistency to match the auto brazing system.
Gathering numerous test results from industrial research, we confirmed the ratio of flux to filler metal to design the product, making sure the continuity and efficiency.
There are two main kinds of flux cored brazing ring according to different utilities, namely, aluminum flux cored brazing ring, and copper-aluminum flux cored brazing ring.
Advantages of Flux Coated and Flux Cored Alloy Filler Metals:
Labor savings - Simplifies and eliminates a separate fluxing operation.
Produces stronger joints - Less flux entrapped inside the joint, leaving the braze joints with improved strength because the use of coated and cored products has been found to reduce flux inclusions at the joint interface.
Improved operations - The all in one product streamlines customer's supply chain, eliminating the need to buy flux and alloy, while also automating brazing and assembly with high velocity, single piece flow.
Multiple uses - Flux coating can be used for coating of bulk strip, rods, engineered preforms and discrete parts.
Reduced costs - Reduction of post braze cleaning and secondary finishing operations, thereby reducing overall metal-joining costs.
Waste reduction - Flux coating reduces the waste of too little or too much flux, and the consistent application of flux and alloy improves joint quality.
Exposure reduction - Flux contamination within components on plant equipment and in the waste water is dramatically reduced. Flux exposure to brazing personnel is reduced.
