C35330 DZR Brass pipe/tube(CW511L)
C35330 is a dezincification-resistant (DZR) brass alloy primarily composed of copper, zinc, lead, and trace arsenic. It is designed to withstand corrosive environments, particularly chlorinated water systems, while maintaining excellent machinability and cold-forming properties. The alloy’s alpha-phase structure, combined with heat treatment, ensures resistance to dezincification—a common failure mode in high-zinc brasses exposed to aggressive fluids. Typical applications include plumbing hardware, valve components, and fittings in potable water systems .

Dimensional Specifications for Tubes

While exact tube dimensions (OD, ID, wall thickness) are application-specific and often customized, the following ranges are typical for seamless brass tubes:

  • Outside Diameter (OD): 6–50 mm (standard), up to 150 mm for specialized fittings.
  • Wall Thickness: 1–5 mm (common), adjustable for pressure requirements.
  • Length: Standard lengths up to 3 meters; custom lengths available .

Note: Tubes adhere to tight tolerances (e.g., ±0.06 mm for OD) and are deburred/machined for precision .

International Standards

C35330 complies with key global standards for composition, performance, and dimensional consistency:

  1. ASTM B453/B453M: Specifies requirements for leaded brass bars, rods, and tubes (UNS C35330) .
  2. EN 12164 (CW602N): European standard for CuZn36Pb2As brass, equivalent to C35330 .
  3. BS 2873 (CZ132): British standard for dezincification-resistant brass tubing .
  4. ISO 7005/ISO 7268: Guidelines for pressure-rated fittings and threaded connections in plumbing systems .

Chemical Composition

C35330 is a leaded arsenical brass (also called Dezincification Resistant Brass, DZR Brass) with a carefully balanced composition to ensure machinability, corrosion resistance, and dezincification resistance. Its chemical composition varies slightly depending on standards but generally adheres to the following ranges:

ElementComposition Range (%)Notes/References
Copper (Cu)59.5–64% (min. 59.5%)Primary base metal .
Zinc (Zn)32.25–39%Balances the alloy; adjusted based on Cu content .
Lead (Pb)1.5–3.5%Enhances machinability; critical for high-speed machining .
Arsenic (As)0.02–0.15%Added to inhibit dezincification .
Tin (Sn)≤0.2%Impurity limit .
Iron (Fe)≤0.2%Impurity limit .
Total Impurities≤0.5%Includes trace elements like Sb, Ni, etc. .

Key Points:

  • The alloy is standardized under ASTM B453/B453M (UNS C35330) and equivalent to CW602N (EN) and CZ132 (BS) .
  • The addition of arsenic (0.08–0.15%) is critical for resisting dezincification in chlorinated water environments .

Mechanical Properties

The mechanical properties of C35330 vary significantly with temper condition (e.g., annealed, cold-worked) and product form (bars, rods, wires). Below are typical values based on ASTM standards and industrial

B. Additional Properties
  • Elastic Modulus: ~117 GPa .
  • Shear Modulus: ~39 GPa .
  • Machinability: Rated 90% (vs. 100% for free-cutting brass C36000) .
  • Thermal Conductivity: 115 W/m·K .
  • Density: ~8.9 g/cm³ .
C. Key Observations:
  1. Soft Annealed (O60) State: Optimized for ductility and forming, suitable for plumbing fittings and valve components .
  2. Cold-Worked States (H01/H02): Higher strength for load-bearing applications like valve spindles and hardware .
  3. Dezincification Resistance: Achieved through arsenic addition and heat treatment, making it ideal for potable water systems .
