Copper Alloy Sheet C11000/C26000 - 0.1-10mm Thickness ASTM B152 For
Electrical Contacts
C11000/C26000 Copper Alloy Sheets are precision-engineered for high-performance electrical contacts,
connectors, and terminals requiring excellent conductivity, corrosion resistance, and mechanical durability. Compliant with ASTM B152, EN 1652, and JIS H3100 standards, these sheets are available in thicknesses from 0.1mm to 10mm, catering to industries like automotive electronics, renewable
energy, and consumer appliances.
Key Advantages:
- High Electrical Conductivity: C11000 (100% IACS) and C26000 (28% IACS) for efficient current
transfer.
- Superior Formability: C26000 (cartridge brass) offers excellent bendability for complex
stamped contacts.
- Corrosion Resistance: Resists oxidation, sulfidation, and humidity (tested per ASTM
B117).
- Precision Thickness: Tight tolerances (±0.01mm for ≤1mm, ±0.02mm for >1mm) for
consistent performance.
- Global Compliance: RoHS, REACH, and ISO 9001-certified production.
- Custom Solutions: Pre-cut blanks, perforated patterns, and selective gold/silver
plating.
