1. Common Product Forms of Pure Copper
Pure copper is commercially available in several typical product forms to meet different processing and application requirements.
1.1 Copper Sheet (Plate)
Copper sheet and plate are produced by flat rolling. Sheets are relatively thin and used in gaskets, electrical components, heat sinks, decoration, and shielding parts. Plates are thicker and applied in structural parts, molds, base materials, and electrode materials.
1.2 Copper Bar (Rod)
Copper bar is mainly manufactured by extrusion or drawing. It has high strength and good machinability, widely used in shafts, bolts, electrical contacts, electrodes, welding materials, and machined parts.
1.3 Copper Tube
Copper tube has excellent formability and heat transfer performance. It is extensively used in water supply systems, air conditioning, refrigeration, heat exchangers, plumbing, and gas pipelines.
1.4 Copper Strip (Coil)
Copper strip is thin and supplied in coils. It is suitable for continuous stamping, connectors, terminals, busbars, shielding materials, and laminated products.
1.5 Copper Wire
Copper wire is produced by multi‑pass drawing. It is the most widely used form in cables, wires, motor windings, electromagnetic coils, electrical connections, and braided wires.
Other forms include copper foil, copper forgings, copper profiles, and copper pipes with special sections, but the five categories above are the most common.
2. Common Diameter Specifications of Pure Copper Bars
Pure copper bars are generally available in diameters ranging from small precision sizes to large structural sizes.
Small diameters: 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm
Medium diameters: 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, 22 mm, 25 mm, 28 mm, 30 mm
Large diameters: 35 mm, 40 mm, 45 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm
Customized diameters above 100 mm can be produced by extrusion.
Lengths are typically 2 m, 2.5 m, 3 m, or cut to order. Surface conditions include drawn (bright), extruded (black oxide), and turned (machined).
3. Common Length and Width Dimensions of Pure Copper Sheets
Pure copper sheets and plates follow standard metric dimensions for easy cutting and processing.
Thickness range:
Thin sheet: 0.2 mm – 3.0 mm
Medium plate: 3.0 mm – 10 mm
Thick plate: 10 mm – 50 mm or more
Standard width × length combinations:
600 mm × 1500 mm
1000 mm × 2000 mm
1220 mm × 2440 mm
1000 mm × 2500 mm
1500 mm × 3000 mm
Special widths such as 500 mm, 800 mm, 1200 mm are also commonly supplied. Lengths can be slit or cut according to customer requirements.
Conclusion
Pure copper is supplied in versatile forms including sheet, bar, tube, strip, and wire, covering almost all industrial needs. Copper bars are available in a complete range of diameters from 2 mm to over 100 mm. Copper sheets follow international standard dimensions for convenient logistics and processing.
