Define thickness and flatness separately
Thickness tolerance controls material gauge; flatness controls the surface profile across the panel. Include the measuring area and any tighter requirement for contact or mating faces.
Copper sheets & plates
Copper sheet and plate for formed parts, conductive blanks, thermal components and architectural details. Specify thickness, panel size, material condition and surface expectations for your project.

01 / SIZES & SELECTION
Thickness is only the first dimension.
Thin sheet is often selected for forming; thicker plate provides stock for machining. The examples below help structure an inquiry. Specify the full thickness × width × length and whether you need a stock panel or a finished blank.
The dimensions below are practical sourcing examples, not a confirmed stock list or manufacturing limit. Supply combinations and tolerances are confirmed for the selected grade, temper and order.
| Form / dimension | Common inquiry examples | Selection notes |
|---|---|---|
| Thin sheet · thickness | 0.5, 0.8, 1.0, 1.5, 2.0 mm | Formed covers, stamped blanks and decorative details; include bend direction, temper and handling needs. |
| Sheet · thickness | 3, 4, 5, 6 mm | Fabricated blanks, conductive plates and equipment panels; agree cutting method, edge condition and flatness. |
| Plate · thickness | 8, 10, 12, 15, 20 mm | Machined thermal parts and contact blocks; allow for face machining and control finished thickness separately. |
| Heavy plate · thickness | 25, 30, 40, 50 mm | Thicker machining blanks and thermal blocks; review grade, internal-quality needs, piece weight and lifting arrangements. |
| Panel format · width × length | 1,000 × 2,000 mm as an inquiry format; cut sizes by drawing | Panel availability depends on thickness, grade and temper. A nominal panel dimension does not define squareness or edge tolerance. |
| Cut-size blank | 200 × 300 mm or 500 × 500 mm examples; thickness stated separately | Provide the nesting / cut list, piece count, grain direction if relevant and remaining machining allowance. |
Plan the usable surface
State which face is visible or functional, the permitted scratches, finish direction and protective film. For formed parts, include bend radius, rolling direction and temper in the drawing.
Specify the panel you can actually use
- Agree thickness, width, length, squareness and flatness acceptance limits using the selected standard or drawing.
- Identify burr height, cut edge quality, corner condition, surface marks and any material left for machining.
- For critical plate, request the internal-quality checks and material evidence the design needs, with method and limits agreed before ordering.
02 / MATERIAL & TEMPER01 02 03
Choose the grade for the job.
C11000 · ETP copper
Commonly considered for conductive sheet blanks and general fabrication. Define conductivity, strength and forming needs rather than selecting by colour or purity alone.
C10200 / C10100 · oxygen-free copper
A grade request for specified electrical, thermal or joining requirements. State the exact designation, condition and required test evidence for the component.
C12200 · DHP copper
A deoxidized copper option for forming and suitable joining or architectural requirements. Conductivity differs from electrical grades; specify ASTM B152/B152M or the relevant product standard and temper.
From formed sheet to machined plate.
Electrical blanks & contact plates
Sheet and plate can be cut into terminal plates, conductive links and contact blanks. Grade, conductivity, hole layout and contact-surface condition should match the electrical assembly design.
Heat spreaders & thermal blocks
Plate provides machining stock for heat-spreading bases and thermal interfaces. Final flatness, thickness and contact finish should be defined on the part drawing; material thickness alone does not define thermal performance.
Stamping, bending & formed covers
Thinner sheet can be blanked and formed into covers, shields and fabricated components. Temper, rolling direction and bend radius help determine forming behaviour and surface appearance.
Architectural & decorative details
Copper sheet can be formed into cladding details, decorative panels and crafted surfaces. Specify finish direction, matching appearance and protection; natural oxidation changes the colour over time.
04 / PROCESSING & FINISH01 02 03 04
Define the delivery condition.
Full panels or cut blanks
Provide a cut list and identify rough blanks versus finished dimensions. Sheared or saw-cut material may require finishing; the method and allowances are confirmed in the quotation.
Machining & drilling
For holes, slots, milled faces or shaped blanks, provide the drawing and inspection dimensions. Requested processing is reviewed before being offered as part of the order.
Surface protection
Request interleaving paper, protective film or an agreed surface finish. Define whether one or both faces need cosmetic protection and whether the film is suitable for your next operation.
Edges & forming allowance
Specify deburring, corner radii, edge finish and forming direction. Separate stock flatness from any tighter flatness needed after bending or machining.
Inspection & documentation
- Agree dimensional and surface inspection, grade / batch identification and material condition.
- Specify conductivity, hardness or mechanical-property evidence and any plate internal-quality checks required by the design.
- List material reports, conformity documents and third-party inspection requirements with the quotation request.
Packing & storage
- Discuss interleaving, edge guards, moisture protection and flat support on a pallet or in a case.
- State the maximum package weight, lifting restrictions and destination packaging rules.
- Store dry with full support; use clean handling protection, keep faces separated and retain batch labels.

Sheet & plate buying questions
Where does sheet end and plate begin?+
The terminology depends on the product standard and market. State the exact thickness and specification rather than relying on the word sheet or plate to define the order.
Can the surface stay bright during storage?+
Clean, dry storage and suitable interleaving or protective film reduce handling marks and moisture exposure. Copper naturally oxidizes; agree any appearance and packaging criteria before shipment.
Is cut-to-size material ready for final assembly?+
Only when the agreed finish, dimensions and tolerances meet the assembly drawing. A rough cut blank may need edge finishing or machining before use.
