UNS Number: C27000
Common Names: Brass (65% Cu, 35% Zn), 65/35 Brass
Applicable Standards:
ASTM B36/B36M (Brass Sheet/Strip)
ASTM B134 (Brass Wire)
SAE J463 (Wrought Copper Alloys)
DIN 17660 (European Standard: 2.0360)
Product Features
Superior Cold Formability: Ideal for deep drawing, bending, and complex forming operations.
High Strength-Ductility Balance: >50% elongation in annealed state; strength significantly increases after cold working.
Good Corrosion Resistance: Suitable for atmospheric, freshwater, and low-corrosion industrial environments.
Excellent Machinability: Delivers high surface finish with minimal tool wear.
Eco-Friendly & Cost-Effective: Lead content ≤0.07% (RoHS compliant); optimized zinc content reduces material costs.
Decorative Appeal: Bright yellow surface ideal for architectural and consumer product designs.

Core Advantages
1. Exceptional Cold Formability: >95% success rate in deep drawing (e.g., cartridge cases, precision stampings).
2. High Cost Efficiency: 35% zinc content reduces raw material costs for high-volume production.
3. Surface Treatment Adaptability: Compatible with plating, polishing, and painting for functional/decorative uses.
4. Environmental Resistance: Resists oxidation in humid conditions and corrosion in freshwater.
Product Applications
Architectural Decor: Door handles, light fixtures, trim.
Electronics: Connectors, terminals, EMI shielding.
Automotive: Radiator cores, fuel system components.
Plumbing: Low-pressure valve bodies, fittings.
Industrial: Fasteners, springs, stamped hardware.
Processing Guidelines
Hot Working: Control temp. at 820–870°C; avoid edge cracking (hot extrusion recommended).
Cold Working: Anneal (600–700°C) to restore ductility; use lubricants to prevent galling.
Welding: Compatible with TIG/resistance welding. Apply low-temp stress relief (260–270°C); limit heat input to prevent zinc vaporization.
Surface Treatment: Acid clean before plating; apply clear coat for decorative parts.
Key Application Scenarios
Architectural Restoration: Vintage hardware for hotels/historical buildings.
Electronics Manufacturing: Stamped terminals for mobile devices/PCs.
Automotive Thermal Systems: Radiator cores in EVs.
Plumbing Hardware: Valves and bathroom accessories.
