What is ASTM B61 UNS C92200?
ASTM B61 is a standard specification covering steam or valve bronze castings used in pressure applications. Under this standard, Copper Alloy UNS C92200 (also called Copper Alloy UNS No. C92200) is a high-leaded tin bronze alloy designed for strong mechanical performance and excellent machinability.
You may see it referenced in project documentation as:
- ASTM B61 UNS C92200
- UNS C92200 copper alloy
- ASTM B61 Copper Alloy C92200 Fittings
This alloy is specially engineered for cast fittings that must handle fluid pressure safely and consistently.
