Product Description
C1100 Industrial Copper Plate Sheet 1.0-20mm for CNC Machining and Electrical Fabrication
Product Overview
Our C1100 industrial copper plate sheet in mill finish is a workhorse material for CNC machining, electrical busbar fabrication, and heavy industrial applications. Available from 1.0mm to 20mm thickness with custom cut-to-size service, each plate is produced from certified electrolytic copper cathode with guaranteed ≥100% IACS conductivity for demanding electrical and mechanical engineering requirements.
Key Features
- Wide Thickness Range 1.0-20mm: From thin gauge for stamped electrical components to heavy plate for machined busbar assemblies and transformer parts. Tight thickness tolerances ensure consistent machining results across production batches.
- 100% IACS Guaranteed Conductivity: Every production batch is tested to ASTM B187, with mill test reports provided. This is critical for electrical busbar and switchgear applications where conductivity directly determines system efficiency and thermal performance.
- CNC-Ready Material: Supplied in uniform temper (typically H02 half-hard) for predictable machining behavior. Excellent chip formation characteristics for milling, drilling, tapping, and waterjet or laser cutting.
- Custom Processing Services: Beyond supplying plate stock, we offer CNC plasma cutting, laser cutting, waterjet cutting, precision drilling, tapping, and bending to your engineering drawings. Receive ready-to-assemble components, not just raw plate.
- Large Format Availability: Plates up to 2000mm width and 6000mm length available, reducing weld joints in large busbar assemblies and fabrication projects.
