UNS C42200 Tin Brass
C42200 brass is a brass formulated for primary forming into wrought products. It has a moderately high melting temperature among wrought brasses. In addition, it has a moderately high base cost and a moderately high thermal conductivity.
The properties of C42200 brass include nine common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare C42200 brass to: wrought brasses (top), all copper alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Alloy Composition
Among wrought copper alloys, the composition of C42200 brass is notable for including phosphorus (P) and tin (Sn). Phosphorus is used as an alloy deoxidizer, and to reduce vulnerability to dezincification. Tin is used to improve strength, bearing properties, and corrosion resistance against certain types of media.
