Comparing CuZn15 with Other Brass Alloys

When choosing a brass alloy for your project, it’s important to compare CuZn15 with other available options to ensure it meets your needs. Below, we compare CuZn15 with some other common brass alloys to highlight the differences in formability, korrosionsbeständighet, och cost.

CuZn15 Compared to Other Brass Alloys

Key Comparisons:

• CuZn15 vs. CuZn30: CuZn30 has higher draghållfasthet compared to CuZn15, making it better suited for applications that require more mechanical strength. However, CuZn15 offers better formability and is a more cost-effective solution for decorative and low-stress applications.
• CuZn15 vs. CuZn37: CuZn37, with its higher zinc content, offers better machinability but is less corrosion-resistant than CuZn15. This makes CuZn15 a better choice for plumbing och decorative applications where corrosion resistance is a priority.
• CuZn15 vs. CuZn39Pb3: CuZn39Pb3 is a leaded brass, meaning it is easier to machine but is less workable in cold-forming processes. CuZn15, on the other hand, excels in formability and is often preferred for cold-working processes som deep drawing.
