C270 Brass: Yellow Brass and Product Specification

C27000 is a yellow-brass designation in the UNS system. Material reference.

Yellow Brass and Product Specification

Before accepting a C26800 or H65 alternative, compare the complete composition limits and the relevant product specification. A common nominal copper description is only an initial comparison, not proof of equivalence. For formed parts, delivered temper must also be matched.

Manufacturing and acceptance checks

Specify whether the order is for sheet, strip, tube or bar and state the required condition. Define the forming or machining operation and final dimensional checks. Ask the supplier to identify the proposed substitute on its certificate and approve the change before production stock is released.
