CuZn36Pb1.5 Brass

Brass

Designation

CuZn36Pb1.5 (Leaded High-Zinc Brass)

International Standards: C3561 (JIS), CZ124Pb (BS), GB/T 1176-2013 (China).


Key Features

1. Superior Machinability: Lead content 1.2–1.8%, improves cutting efficiency by 30–50%.

2. Strength & Corrosion Resistance: Zn 36%, Cu 60–63%, stable in atmospheric environments.

3. Surface Finish: Post-machining roughness Ra 0.8–1.6μm.

4. RoHS Compliance: Lead content complies with industrial exemptions.

Core Advantages

1. High Efficiency Machining: Chip-breaking performance reduces tool wear.

2. Precision Surface: Ideal for high-tolerance components.

3. Cost Savings: 30% lower machining costs vs. lead-free brass.


Applications

  • Automotive: Fuel injectors, sensor housings.

  • Electronics: RF connectors, precision screws.

  • Plumbing: Valve cores, faucet components.


Processing Guidelines

1. Machining: Cutting speed 80–120 m/min, feed rate 0.1–0.3 mm/rev.

2. Safety: Use fume extraction to avoid lead exposure.

3. Welding: Prohibit fusion welding; use silver-based brazing.
