UNS C41300 Tin Brass

C41300 brass is a brass formulated for primary forming into wrought products. It has a moderately high base cost among wrought brasses. In addition, it has a moderately high melting temperature and a moderately high thermal conductivity.

The properties of C41300 brass include ten 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 C41300 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.
