UNS Number: C35000
Common Name: Leaded Brass (CuZn39Pb)
Corresponding Standards: ASTM B453 (Leaded Brass Rod/Bar), ASTM B121 (Leaded Brass Sheet/Strip), DIN 17671-1.
Product Features
Superior Machinability: Lead content (1.5–2.5%) ensures excellent chip-breaking and reduced tool wear.
High Corrosion Resistance: Suitable for atmospheric, freshwater, and mild marine environments.
Balanced Strength-Ductility: Tensile strength up to 550 MPa with elongation up to 50%.
Cost-Effective: Lower copper content (58–62%) reduces material costs.
Thermal Conductivity: Ideal for heat exchanger components.

Core Advantages
1. Free-Machining: Ideal for high-speed CNC and automatic machining.
2. Durability: Resists wear and corrosion in humid environments.
3. Versatility: Compatible with hot forging, cold forming, and welding.
4. Cost Efficiency: Optimized for mass production in automotive and electronics industries.
Product Applications
Automotive: Radiator cores, fuel injectors, and stamped components.
Electronics: Connectors, terminals, and shielding parts.
Plumbing: Valve bodies, fittings, and pump components.
Industrial: Gears, bushings, and fasteners.
Marine: Non-critical seawater components (with coatings).
Processing Considerations
Annealing: 500–650°C for 1–2 hours to restore ductility after cold working.
Machining: Use sharp carbide tools with lubricants to minimize galling.
Welding: TIG welding with inert gas shielding; avoid overheating to prevent lead vaporization.
Surface Treatment: Electroplating or passivation for enhanced corrosion resistance.
FAQs
Q1: Is C35000 suitable for drinking water systems?
A: Limited use due to lead content; ensure compliance with local regulations (e.g., NSF/ANSI 61).
Q2: How does C35000 compare to C36000 brass?
A: C35000 has lower lead content (2.5% max vs. 3.7% in C36000), offering better environmental compliance but slightly reduced machinability.
Q3: Can C35000 be recycled?
A: Yes, but specialized recycling processes are required to manage lead content safely.
