FAQ
| What is C28000 brass? C28000 brass is a standardized copper-zinc alloy under the UNS system, commonly known as Muntz Metal. It contains approximately 60% copper and 40% zinc, offering a good balance of strength, formability, and corrosion resistance. |
| What is the chemical composition of C28000 brass? The nominal composition is 60.0-63.0% copper, 0.30% maximum lead, 0.07% maximum iron, and the remainder being zinc. The total of other impurities is limited to 0.15%. |
| What is C28000 brass equivalent to? C28000 brass is the direct U.S. equivalent to China's H62 brass, Europe's CuZn37 (CW508L), and Japan's C2800 brass. |
| What are the mechanical properties of C28000 brass? In the annealed condition, typical properties include a tensile strength of ≥ 370 MPa, yield strength of ≥ 150 MPa, elongation of ≥ 20%, and a hardness of approximately 65 HRB. |
| What is the machinability rating of C28000 brass? C28000 brass has a fair machinability rating of around 40% on the standard scale where free-cutting brass C36000 is rated at 100%. It produces continuous chips. |
| What is C28000 brass used for? C28000 brass is widely used in architectural hardware (hinges, locks), electrical connectors, heat exchanger components, plumbing fittings, decorative trim, and various stamped parts. |
