Standard – Standard Specification for Phosphor Bronze Rod, Bar, and Shapes ASTM B/BM –

It has good resistance to corrosion, including stress corrosion. This specification establishes the requirements for rods, bars, and shapes of phosphor bronze with Copper Alloy UNS Nos. In addition, it has good cold forming properties and spring properties with excellent resistance to stress relaxation.

The alloy can be manufactured in a range of different combinations of ductility and strength including the hard temper, which produces high tensile strength and good fatigue properties whilst retaining good ductility. If the document is revised or amended, you will be notified by email. You may delete a document from your Alert Profile at any time.

C brazes and solders extremely well and has excellent cold working capacity.

C, C, C, C, and C This standard is also available to be included in Standards Subscriptions. The tin increase the strength of the alloy and gives good corrosion resistance in marine environments.
