Factory high quality 40% silver copper alloy solder ring

Product Description

Specifications 1.Good fluidity.
2.For brazing refrigeration, air-condition etc.

Factory high quality 40% silver copper alloy solder ring BAg-28 Silver Brazing Alloy is used for the brazing of copper and copper alloys, brass and bronze. It can also be used on silver, tungsten and molybdenum. It is primarily used for the joining of copper to copper on vibration free joints. It is very effective for joining tight fitting and tubing. BAg-28 is extremely fluid at temperatures and will penetrate joints with very little clearance. The phosphorus content of BAg-28 acts as a fluxing agent and no flux is necessary when brazing copper to copper joints. However, when used with a copper alloy or one of the brazeable metals, a flux must be used to promote wetting, bonding and flow throughout the joint.
