Product Description
Our C11000 precision tolerance copper strip is engineered for high-speed progressive die stamping of electronic connectors, lead frames, and precision terminals where ±0.01mm thickness consistency is critical for production yield and part quality. With custom width CNC slitting from 6mm to 600mm and thickness from 0.1mm to 3.0mm, every coil undergoes comprehensive verification by laser micrometer across the entire strip length.
- ±0.01mm Thickness Tolerance: Achieved through precision cold rolling and in-line laser micrometer gauging. This tight tolerance eliminates die wear variation and ensures uniform contact force across millions of stamped parts per coil.
- Custom Width CNC Slitting (6-600mm): Computer-controlled slitting lines deliver width tolerances of ±0.05mm with burr-free edges. We slit to your exact drawing specifications, eliminating secondary trimming operations at your facility.
- 100% IACS Conductivity: C11000 electrolytic tough pitch copper ensures maximum electrical conductivity for low-resistance connector contacts and minimal joule heating in high-current applications.
- Mirror-Grade Bright Annealed Surface: Controlled atmosphere annealing produces an oxide-free, mirror-bright surface ideal for gold, silver, or tin electroplating without additional cleaning steps.
- Multiple Temper Options: Available in annealed (O), quarter-hard (H01), and half-hard (H02) tempers to match your specific stamping, bending, and forming requirements.
