Brass CuZN40 Plates Suppliers

Brass CuZn40 plates, also known as CW509L brass plates, are widely used across engineering, fabrication, and industrial manufacturing sectors due to their excellent strength, corrosion resistance, and formability. With a balanced copper‑zinc composition, CuZn40 brass plates offer superior mechanical properties compared to standard brass grades, making them ideal for heavy‑duty and precision applications.

For buyers looking for a reliable, long‑term material solution, Brass CuZn40 plates deliver a strong combination of durability, machinability, and cost efficiency.

What is Brass CuZn40?

Brass CuZn40 is a high‑zinc brass alloy consisting of approximately 60% copper and 40% zinc. This composition enhances tensile strength while maintaining good ductility, allowing the plates to be easily cut, bent, welded, and machined.

Equivalent Standards:

  • EN: CW509L

  • DIN: CuZn40

  • ASTM: C28000

  • IS: IS 319 Type II

Chemical Composition of Brass CuZn40 Plates

ElementPercentage
Copper (Cu)59 – 61%
Zinc (Zn)Balance
Iron (Fe)≤ 0.05%
Lead (Pb)≤ 0.05%

This optimized composition ensures high strength, wear resistance, and long service life.

Mechanical Properties

  • Tensile Strength: 430 – 550 MPa

  • Yield Strength: ≥ 180 MPa

  • Elongation: 20 – 25%

  • Hardness: 120 – 160 HB

These properties make Brass CuZn40 plates suitable for load‑bearing and high‑stress environments.

Key Advantages of Brass CuZn40 Plates

1. High Mechanical Strength

CuZn40 plates provide better strength than low‑zinc brass grades, making them suitable for structural and mechanical components.

2. Excellent Corrosion Resistance

They perform exceptionally well in marine, industrial, and mildly corrosive environments, ensuring long‑term reliability.

3. Good Machinability & Fabrication

Brass CuZn40 plates are easy to machine, drill, cut, and weld, reducing manufacturing time and costs.

4. Cost‑Effective Alternative

Compared to pure copper alloys, CuZn40 brass plates offer similar performance at a more economical price point.

5. Attractive Surface Finish

The natural golden finish makes them suitable for decorative and architectural uses as well.

Commercial & Industrial Applications

Brass CuZn40 plates are widely used in:

  • Electrical components & terminals

  • Heat exchangers & condenser plates

  • Marine fittings & shipbuilding parts

  • Automotive components

  • Architectural panels & decorative works

  • Industrial machinery & heavy fabrication

  • Valve plates, flanges & fasteners

Their versatility makes them a preferred choice for both OEM manufacturers and bulk industrial buyers.

Available Sizes & Specifications

Brass CuZn40 plates are available in:

  • Thickness: 0.5 mm to 100 mm

  • Width: Up to 1500 mm

  • Length: Custom cut sizes available

  • Finish: Mill finish, polished, brushed

Custom sizes and surface finishes can be supplied as per project requirements.
