CuZn37

CuZn37, also known as C37000 or Brass Alloy 37, is a brass alloy that contains approximately 37% zinc and 63% copper. It is known for its excellent mechanical properties, corrosion resistance, and machinability. CuZn37 is one of the most commonly used brass alloys for die casting, making it ideal for a variety of industrial applications, including those requiring high-strength, durable components that are easy to machine.

At Neway, we specialize in providing high-quality CuZn37 die casting solutions. Our advanced CNC machining, tooling, and surface finishing capabilities ensure precision-engineered parts with superior mechanical properties and corrosion resistance.

Key Characteristics of CuZn37

CuZn37 offers a balanced combination of mechanical properties, excellent corrosion resistance, and high machinability. It is well-suited for precision die casting applications where strength and durability are critical, and where parts need to maintain dimensional stability over time.

The alloy’s copper content provides good thermal and electrical conductivity, while the zinc content increases its strength and hardness. CuZn37 is particularly known for its high resistance to atmospheric and water corrosion.

Chemical Composition of CuZn37

The copper content in CuZn37 offers good conductivity and corrosion resistance, making it suitable for parts exposed to moisture or atmospheric conditions.

Mechanical Properties of CuZn37 Brass Alloy

CuZn37 offers excellent mechanical properties that make it ideal for producing durable, high-performance components. Below are the typical mechanical properties of CuZn37:

These properties make CuZn37 a strong, durable, and versatile material, suitable for applications that require high-strength parts and for use in corrosive environments.

Benefits of Using CuZn37 in Die Casting

• Excellent Strength: CuZn37 provides high tensile and yield strength, making it suitable for parts that can withstand mechanical stress.

• Good Corrosion Resistance: The copper content gives CuZn37 excellent corrosion resistance, especially in outdoor, marine, and plumbing applications.

• High Machinability: CuZn37 is easy to machine and provides smooth, clean cuts, making it ideal for applications requiring precise finishes.

• Good Thermal and Electrical Conductivity: CuZn37 is an excellent material for components requiring good heat dissipation or electrical conductivity.

• Dimensional Stability: CuZn37 maintains its shape and size over time, even when exposed to high temperatures or harsh environmental conditions.

Typical Applications of CuZn37 Die Cast Parts

CuZn37 is commonly used in applications where strength, durability, and machinability are essential. Typical uses of CuZn37 include:

• Automotive: Engine components, radiator parts, and structural brackets

• Plumbing: Fittings, faucets, valves, and plumbing connectors

• Electronics: Electrical connectors, terminals, and housings for electrical devices

• Industrial Equipment: Pump components, valve bodies, and machinery parts

• Marine: Corrosion-resistant fittings, fasteners, and components for marine applications

CuZn37’s strength, corrosion resistance, and machinability makes it ideal for precision-engineered parts exposed to demanding environments.

CNC Machining Considerations for CuZn37

CuZn37 is known for its excellent machinability, especially compared to other copper alloys. However, its high strength and hardness require carefully selecting cutting tools and techniques.

Machining Recommendations:

• Tooling: Carbide tools or high-speed steel tools are recommended for machining CuZn37. TiAlN-coated tools can help reduce wear due to the alloy’s hardness.

• Cutting Speed: Milling: 250–400 m/min; drilling: 100–150 m/min

• Feed Rate: 0.05–0.15 mm/rev depending on the complexity of the part and tool size

• Coolants: Use water-based or synthetic coolants to prevent overheating and ensure smooth cuts.

• Surface Finish: Ra ≤ 1.6 µm achievable for functional or aesthetic parts.

• Tolerance: ±0.03 mm achievable for critical features.

Neway’s CNC machining services ensure precise machining and superior finishes for CuZn37 die cast parts, meeting tight tolerances and high-quality standards.

Surface Treatments for CuZn37 Parts

To further enhance the performance of CuZn37, several surface treatments can be applied:

• Anodizing: Increases corrosion resistance and offers a decorative finish.

• Powder Coating: Adds color and protection, ideal for parts exposed to harsh environments.

• Painting: Provides UV and chemical resistance for outdoor applications.

• Tumbling: Removes burrs and smooths surfaces before further finishing or coating.

All surface treatments are tested to ensure optimal adhesion, durability, and corrosion resistance.
