The investigation covers phosphor copper, which is a master alloy of copper containing 5% or more of phosphorus, by weight. Phosphor copper is used as a deoxidizer, as an alloying additive that increases strength, hardness, and elasticity, and in brazing alloys to lower the melting temperature and improve wetting characteristics. It’s also used in the manufacture of copper tubing and brazing rods and is also used by brass mills and foundries.
