UNS C41500 Tin Brass
C41500 brass is a brass formulated for primary forming into wrought products. It has a moderately high base cost and a moderately high melting temperature among wrought brasses.
The properties of C41500 brass include eight 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 C41500 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.
