UNS Number: C34200
Common Name: Leaded Brass (Low-Lead Brass / CuZn37Pb)
Corresponding Standards: ASTM B453 (Leaded Brass Rod/Bar), ASTM B121 (Leaded Brass Sheet/Strip), DIN 17671-1.
Product Features
Excellent Machinability: Enhanced by lead content (1.5–2.5%) for superior chip-breaking and reduced tool wear.
High Corrosion Resistance: Suitable for atmospheric, freshwater, and limited marine environments.
Balanced Strength-Ductility: Tensile strength up to 586 MPa with elongation up to 60%.
Good Thermal and Electrical Conductivity: Ideal for heat exchangers and low-current electrical components.
Cost-Effective: Lower copper content (62–66.5%) reduces material costs.

Core Advantages
1. Free-Machining: Lead lubrication ensures high precision in automatic and CNC machining.
2. Durability: Resists wear and corrosion in humid and mild chemical environments.
3. Versatility: Compatible with cold/hot forming, welding, and forging.
4. Cost Efficiency: Optimized for high-volume industrial production.
Product Applications
Marine Engineering: Seawater valves, heat exchangers, and ship fittings.
Automotive: Radiator cores, fuel system components, and stamped parts.
Electronics: Connectors, terminals, and shielding components.
Industrial Hardware: Fasteners, gears, and bushings.
Plumbing: Low-pressure fittings and valve bodies.
Processing Considerations
Annealing: 500–700°C for 30–60 minutes to restore ductility after cold working.
Machining: Use sharp tools with lubricants to prevent galling.
Welding: Compatible with TIG and resistance welding; control heat input to avoid lead vaporization.
Surface Treatment: Electroplating or lacquering recommended for decorative uses.
