C19400 Copper Sheet Metal Roll Lead Free 200HV-400HV Hardness For Semiconductor

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.
