Copper and phosphorous, “phos-copper”, brazing alloy offering excellent liquidity for tight fitting joints. Used extensively in the Heating, Ventilating and Air Conditioning (HVAC) industry to make preform brazing rings for evaporators/condensers. Bellman-Melcor has supplied over two billion brazing rings for this market.
Brazeit 0 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 brazing of copper-to-copper on vibration free joints. It is very effective for joining tight fitting copper pipe and tubing. Brazeit 0 should not be used on ferrous metals or copper alloys containing more than 10% nickel because of phosphorus embrittlement due to reactions with iron or nickel. #0 is extremely fluid at brazing temperatures and will penetrate joints with very little clearance. Best results are obtained with clearances of 0.001″ – 0.003″. Melting of #0 is virtually complete at 1350 ºF (732 ºC). Best results are obtained when brazing slightly above this temperature.

The phosphorus content of #0 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 0 is 1350 ºF (732 ºC).
Extensive flow, very fluid, recommended joint clearance .001" to .003" Used with copper, brass and bronze base metal.
Standard forms of Brazeit 0 are wire and preforms.
The operation and maintenance of brazing equipment or facility should conform to the provisions of American National Standard (ANSI) Z49.1, "Safety in Welding and Cutting." For more complete information refer to the Material Safety Data Sheet for #0.
