High-Conductivity Copper Alloy Sheet 85% ACS EN 1652 Compliant
Busbar Material
High-Conductivity Copper Alloy Sheets are engineered for power distribution systems requiring low electrical resistance and long-term reliability. With 85% IACS conductivity (49 MS/m) and compliance with EN 1652, ASTM B152, and IEC 60468 standards, these sheets are ideal for busbars, switchgear, and renewable
energy applications. Available in thicknesses from 0.5mm to 25mm, they combine superior conductivity with excellent mechanical
strength and corrosion resistance.
Key Advantages:
- Optimized Conductivity: 85% IACS for minimal energy loss in high-current systems.
- EN 1652 Compliance: Guaranteed material consistency for EU and global projects.
- Corrosion Resistance: Withstands humidity, sulfur, and industrial atmospheres (ISO 9227
tested).
- Formability: Bend radius down to 1x thickness without cracking (EN ISO 7438).
- Eco-Certified: RoHS, REACH, and ISO 14001-compliant production.
- Custom Solutions: Pre-cut busbar blanks, perforated designs, and tin/silver-plated
surfaces.
