UNS C26200 Yellow Brass

C26200 brass is a brass formulated for primary forming into wrought products. It can have the highest ductility among the wrought brasses in the database.

The properties of C26200 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 C26200 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 C26200 brass is notable for containing comparatively high amounts of lead (Pb) and iron (Fe). Lead is used to improve machinability and bearing properties, at the cost of toxicity. Iron is used to increase strength inexpensively.

Copper (Cu) 67 to 70
Zinc (Zn) 29.6 to 33
Lead (Pb) 0 to 0.070
Iron (Fe) 0 to 0.050
Residuals 0 to 0.3
