Product Information

CW509L, also known as CuZn40 or C28000, is a brass alloy with approximately 60% copper and 40% zinc, designed for applications requiring high strength, good corrosion resistance, and compliance with drinking water regulations. 

Key Characteristics

  • Excellent Hot Workability: CW509L is ideal for forging and hot stamping.
  • Good Cold Formability: Suitable for bending and moderate cold forming.
  • Corrosion Resistance: Good in neutral and mildly aggressive environments; not resistant to acids or humid ammonia.
  • Machinability: Moderate; chip removal is more challenging compared to leaded brasses.

Applications

  • Potable Water Systems: Valves, fittings, and components compliant with EU drinking water regulations.
  • Mechanical and Vehicle Engineering: Bushings, bearings, and structural components.
  • Electrical Engineering: Connectors and parts requiring good conductivity.
  • Sanitary Industry: Turned parts and fittings.
  • Decorative and Architectural Elements: Due to its golden color and corrosion resistance.

CW509L-DW is listed in the European Positive List under Commission Implementing Decision (EU) 2024/367, ensuring compliance with Directive (EU) 2020/2184 for materials in contact with drinking water. This guarantees its suitability for hygienic and safe use in potable water systems.
