Key Features of CW500L CuZn5 Brass
1. Excellent Cold Formability
CuZn5 is described as having very good cold formability and is suitable for bending, stamping and other cold forming processes. This makes it ideal for brass strip, stamping blanks, decorative plates, embossed parts and precision formed components.
2. Copper-Like Color with Improved Strength
Compared with pure copper, CW500L CuZn5 keeps a similar copper-like color and corrosion resistance while offering higher strength due to zinc solid-solution strengthening.
3. Suitable for Electrical & Decorative Components
This grade is widely used in electrical components, jewelry, watch parts, stamping, embossing, cosmetic packaging and metal goods, making it suitable for both functional and appearance-focused manufacturing.
4. Good Joining Performance
Aurubis lists soldering as excellent, brazing as suitable, and several welding options as possible depending on process control. This supports use in assemblies, decorative products and light industrial components.
5. Better Stress Corrosion Behavior Than Higher-Zinc Brass
CuZn5 is reported as less sensitive to stress corrosion cracking than brass alloys with higher zinc content, although stress relief is still recommended when the application environment may create SCC risk.
6. RoHS / ELV-Oriented Composition
Aurubis notes that the listed CuZn5 composition is in accordance with RoHS for electric and electronic components and ELV for the automotive industry. For strict compliance orders, buyers should request a formal declaration with each shipment.
