The aluminum brazing rod has a 12% silicon alloy with a lower melting point and higher fluidity. No additional flux is required and can be used directly with flame brazing or induction welding. It can also be used as a weld filler metal to increase the silicon content of the weld metal, thereby minimizing hot cracks and producing higher fillet weld shear strength. Its self-fluxing improves the quality of the weld, simplifies operation and increases productivity. The aluminum cored wire brazing rod is made of environmentally friendly non-corrosive flux. It does not need to be cleaned after welding, does not need pickling, and has little harm to the base metal.
1. Save manpower - Simplify and eliminate individual fluxing operations.
2. Produce stronger joints - Capture less flux inside the joints to give the brazed joints a higher strength, as it has been found that the use of coatings and cored products reduces flux inclusions at the joint interface.
3. Improved operation - The integrated product simplifies the customer's supply chain without the need to purchase flux and alloys, as well as automated brazing and assembly through high-speed single-piece flow.
4. Multiple uses - Flux coatings can be used for the coating of bulk strips, rods, engineered parts and discrete parts.
5. Reduce costs - Reduce post-brazing cleaning and secondary finishing operations, thereby reducing overall metal joining costs.
6. Reduce waste - Flux coating reduces too little or too much flux waste, and consistent application of flux and alloy improves joint quality.
7. Reduce exposure - Flux contamination in components in plant equipment and wastewater is greatly reduced. Reduced solder exposure to brazed personnel.
