C19400 Copper Alloy Sheet Rolls are precision-engineered for semiconductor and electronics industries requiring high electrical conductivity, lead-free compliance, and mechanical durability. With a hardness range of 200–400 HV and compliance with ASTM B194, RoHS, and SEMI F72 standards, these sheets are ideal for IC lead frames, connectors, and microelectronic components. Available in thicknesses from 0.1mm to 3.0mm, they balance formability and strength for precision stamping and etching processes.
Key Advantages:
- Lead-Free & Eco-Safe: 100% compliant with RoHS, REACH, and WEEE directives.
- High Conductivity: 45% IACS (26 MS/m) for efficient signal transmission in microelectronics.
- Controlled Hardness: 200–400 HV (annealed to hard temper) for wear-resistant components.
- Corrosion Resistance: Resists oxidation and sulfidation in humid environments (ISO 9227).
- Global Compliance: Certified for ASTM B194, JIS H3110 (C1941), and SEMI F72 (semiconductor grade).
- Custom Solutions: Pre-slit coils, micro-etched patterns, and vacuum-packaged rolls.
