Core Advantages

1. High Corrosion Resistance: Performs well in water, steam, and mild chemical environments.

2. Ease of Fabrication: Excellent for stamping, bending, and machining.

3. Decorative Flexibility: Reddish-gold color ideal for architectural and artistic designs.

4. Cost Efficiency: Affordable alternative to higher-copper alloys for non-critical applications.

Product Applications

• Plumbing: Valves, fittings, and water supply tubes.

• Architecture: Decorative trims, door hardware, and lighting fixtures.

• Electrical: Low-voltage connectors, switch components, and terminals.

• Marine: Non-critical marine hardware and decorative fittings.

• Industrial: Bushings, fasteners, and stamped parts.

Processing Considerations

• Annealing: 450–600°C to restore ductility after cold working.

• Machining: Use sharp tools and coolants to prevent material adhesion.

• Welding: Compatible with TIG and soldering; avoid overheating to prevent zinc vaporization.

• Surface Treatment: Polishing or clear coating recommended to preserve aesthetic appeal.

Key Application Scenarios

• Residential and commercial plumbing systems.

• Architectural restoration projects requiring vintage aesthetics.

• Low-stress marine components in freshwater environments.

• Consumer electronics with decorative metal accents.

FAQs

Q1: Can C23000 be used in potable water systems?

A: Yes, it is commonly used for water supply lines and fittings due to its corrosion resistance.

Q2: How does C23000 compare to C22000 brass?

A: C23000 has lower copper content (85% vs. 90%) than C22000, reducing cost but offering similar machinability and slightly lower corrosion resistance.

Q3: Is C23000 suitable for brazing?

A: Yes, but use low-temperature brazing alloys to avoid damaging the zinc content.
