UNS C48600 Dezincification Resistant (DZR) Brass
C48600 brass is a brass formulated for primary forming into wrought products. It can have a moderately low tensile strength among the wrought brasses in the database.
The properties of C48600 brass include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare C48600 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.
