Item # BrazeIt-2
Combination of low silver with high phosphorous creates very good fluidity in this phos-copper brazing alloy. While not quite as liquid as Brazeit #0, tight fit-up is recommended.
Brazeit 2 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 copper pipe and tubing. Brazeit 2 should not be used when brazing ferrous metals or copper alloys containing more than 10% nickel because of phosphorus embrittlement due to reactions with iron or nickel. Brazeit 2 is extremely fluid at brazing temperatures and will penetrate a joint with very little clearance. Best results are obtained with clearances of 0.001″ – 0.003″. Melting of Brazeit 2 is virtually complete at 1300ºF (704ºC). Best results are obtained when brazing slightly above this temperature.

The phosphorus content of Brazeit 2 acts as a fluxing agent and no flux is necessary when brazing copper joints. However, when used with a copper alloy or one of the other brazeable metals, a brazing flux must be used to promote wetting, bonding, and flow throughout the joint. The flow point of Brazeit 2 is 1300 ºF (704 ºC).
Silver addition lowers solidus temperature, not as fluid as Sil. 0, gap clearance .001" to .003".
Standard forms of Brazeit 2 are brazing wire and brazing preforms
