Phosphor Bronze C544

ASTM B103 UNS C51000 phosphor bronze

UNS C52100 Alloy Products

Like brass, phosphor bronze belongs to the copper family. The chemical composition of this alloy includes copper, which is then alloyed with tin and phosphorous. If free machining phosphor bronze is required,  the material will be alloyed with a significant amount of lead. A specification that explicitly caters to this material is ASTM B103. Product belonging to ASTM B103 phosphor bronze are required to be produced by the use of any of the following techniques i.e. hot or cold working, hot or cold rolling, and annealing. Products, according to this specification are to adhere to the parameters given herein.

Primarily the UNS C51000 phosphor bronze must conform to chemical analysis, a tensile strength in addition to the Rockwell hardness tests specified. The Tension test performed on the C53400 Phosphor Bronze material must be such that the longitudinal axis of the unit must be kept parallel to the direction of rolling. Because there are several alloy grades that fall under this specification, the chemical composition of the said alloys is required to conform to UNS designation for e.g. C51000 Phosphor Bronze of the material.

Which is why, a chemical composition test is subjected to each product constructed under this specification including plates, rolled bars, sheets, as well as strips of C52400 Phosphor Bronze. In addition to having good physical properties, the content of copper gives the C544 Phosphor bronze components a fair level of electrical conductivity and good strength in cryogenic environments. Another benefit of using C52100 Phosphor Bronze is that they are reasonable in terms of their costing.
