Item # BrazeIt-5

This phos-copper brazing alloy delivers moderate liquidity and improved gap filling compared to Brazeit #0. The 5% silver content provides good economy when compared with Brazeit #15.

Brazeit 5 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. Brazeit 5 should not be used when brazing ferrous metals or copper alloys containing more than 10% nickel because of phosphorus embrittlement due to reaction with iron or nickel. Brazeit 5 has good flow and wetting properties on copper, brass, and bronze. Its melting characteristics are such that on the low end of its brazing temperature range it has “sluggish” flow characteristics which enable it to fill gaps better, making it ideal for loose-fitting joints. On the other hand, when brazing at the high end of its brazing temperature range, it is very fluid, making ideal for tight-fitting joints requiring deep penetration.

The phosphorus content of Brazeit 5 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 other brazeable metals, a brazing flux must be used to promote wetting, bonding, and flow throughout the joint. The flow point of Brazeit 5 is 1325 ºF (718 ºC).

Used when gap clearance range is .003 to .006". Ideal for larger copper pipe sizes.

Standard forms of Brazeit 5 are brazing wire and brazing preforms.

The operation and maintenance of brazing equipment or facility should conform to the provision of American National Standard (ANSI) Z49.1, "Safety in Welding and Cutting." For more complete information, refer to the Material Safety Data Sheet for Brazeit 5.
