Core Advantages

1. Superior Formability: Perfect for complex stamped or drawn components.

2. Cost Efficiency: Lower copper content reduces material costs.

3. Decorative Versatility: Bright yellow color ideal for architectural accents.

4. Environmental Resistance: Resists tarnishing in humid conditions.

Product Applications

Decorative: Architectural trim, door handles, and lighting fixtures.
Electronics: Connectors, terminals, and shielding components.
Plumbing: Low-pressure fittings and valve bodies.
Automotive: Radiator cores, fuel system parts.
Industrial: Fasteners, springs, and stamped hardware.

Processing Considerations

Annealing: 425–600°C to restore ductility after cold working.
Machining: Use sharp tools with lubricants to prevent material adhesion.
Welding: Compatible with TIG and resistance welding; minimize heat input to avoid zinc depletion.
Surface Finishing: Electroplating or clear coating recommended for decorative applications.

Key Application Scenarios

Architectural projects requiring corrosion-resistant decorative elements.
High-volume production of stamped automotive components.
Consumer electronics with aesthetic design requirements.
HVAC and plumbing systems in residential buildings.

FAQs

Q1: How does C26800 differ from C26000 brass?

A: C26800 has lower copper content (65% vs. 70%), offering reduced cost but slightly lower strength and conductivity.

Q2: Is C26800 suitable for marine environments?

A: Limited to freshwater or low-salinity applications; protective coatings are recommended for saltwater exposure.

Q3: Can C26800 be recycled?

A: Yes, it is fully recyclable and aligns with sustainable manufacturing practices.
