Product Description
C11000 Copper Plate 0.5–3 mm Bright Finish for Busbars and Electrical Panels
Thin-gauge C11000 plate in bright finish, held in stock for electrical panel builders and busbar fabricators who cannot wait for a rolling programme. The 0.5 mm to 3 mm range covers busbar laminations, earthing strips, switchgear connectors and panel back-plates, with conductivity at or above 100% IACS so resistance and heat build-up stay predictable.
- Material: C11000 electrolytic tough pitch copper, Cu ≥ 99.90%
- Supply form: rolled plate and sheet, cut to size on request
- Capacity: 1000+ tons per month from our Wuxi plant, with plate stock held for urgent orders
- Typical users: panel builders, switchgear manufacturers, earthing and lightning protection contractors

Plates are rolled from certified electrolytic cathode, then processed in-house so the customer receives installation-ready material instead of a mill plate that must be re-worked locally.
- Cutting and slitting: CNC plasma and water-jet cutting, guillotine shearing and slitting lines handle straight cuts, profiles, holes and narrow strips.
- Machining: sawing of heavy plate, edge milling, chamfering and deburring.
- Forming: bending, punching and welding of plate into busbar and panel assemblies on request.
- Surface processing: bright pickling, polishing and PE film protection for visible or decorative faces.
- Inspection at every step: incoming chemistry check, in-process thickness and width measurement, final flatness and visual inspection before packing.
Thin C11000 plate is chosen where current density is high and space is limited. The bright finish also allows direct use without further polishing.
| Industry | Typical part | Why C11000 |
|---|---|---|
| Switchgear and control panels | Busbar, link bars, earthing strip | High conductivity, easy bending and punching |
| Power distribution | Transformer connectors, neutral bars | Stable resistance, low heat rise |
| Electronics | Shielding, heatsink base plates | Thermal and electrical conductivity combined |
| Construction | Earthing and lightning protection tape | Corrosion resistance, long service life |
- Chemical composition: spectrometer analysis on every heat, reported on the MTC.
- Mechanical properties: tensile and elongation tested per batch to ASTM B152.
- Dimension and flatness: thickness gauge and straight-edge check on each bundle, recorded on the inspection sheet.
- Surface: 100% visual inspection under daylight lamps; protective PE film applied where required.
- Packing: interleaving paper between plates, anti-moisture film wrap, fumigated wooden pallet, steel strapping and corner protectors; container loading photos sent before departure.
- Real capacity: 1000+ tons per month with plate stock of 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 10 mm and 20 mm held in Wuxi.
- In-house processing: cutting, slitting, sawing and machining under one roof, so lead time is not lost to subcontractors.
- Honest lead times: 3 working days for stock sizes, 7–15 working days for production.
- Low entry quantity: MOQ 100 kg, so a buyer can verify quality on a trial pallet before committing tonnage.
- Traceable quality: MTC per heat, batch photos and third-party inspection on request.
- Export experience: 80%–90% of output is exported, with sea-freight packing proven on European, Middle East and Southeast Asian routes.
C11000 is electrolytic tough pitch (ETP) copper with roughly 0.02–0.05% oxygen and a minimum of 99.90% Cu. C10200 is oxygen-free copper with oxygen below 0.001% and 99.95% Cu minimum, so it resists hydrogen embrittlement during brazing in vacuum or reducing atmospheres. Choose C11000 for busbars, general fabrication and cost efficiency; choose C10200 for vacuum components, electron tubes and critical brazed assemblies.
ASTM B152 is the standard specification for copper sheet, strip, plate and rolled bar. It defines the required chemical composition, mechanical properties and dimensional tolerances for grades such as C11000, C10200 and C12200. Plates supplied to ASTM B152 are normally certified with a Mill Test Certificate stating heat number, chemistry and mechanical results.
Yes. We slit, shear, saw and CNC cut to your drawing. Standard tolerances are ± 0.1 mm on thickness for cut plate and ± 1 mm on width and length; tighter tolerance down to ± 0.05 mm is available on request. Cut pieces are deburred and individually labelled before packing.
Our C11000 plates run from 0.5 mm to 200 mm. Stock thicknesses are 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 10 mm and 20 mm; other thicknesses are rolled or sawn to order. Thickness tolerance follows ASTM B152 unless a tighter drawing tolerance is specified.
Yes. Every shipment is accompanied by an MTC showing heat number, chemical composition and mechanical properties, issued against the actual production batch. Third-party inspection such as SGS or BV and pre-shipment dimension reports can be arranged on request.
