A general-purpose pure copper material suitable for making conductive parts, thermal components, copper busbar terminals, electrodes, heat dissipation structural components, ordinary precision copper parts, and electronic and electrical connectors.
Pure CopperT2 is a commonly used industrial pure copper material, featuring excellent electrical conductivity, thermal conductivity, ductility, weldability, and good processing properties. It is commonly used in conductive strips, connecting terminals, heat sinks, electrodes, copper gaskets, copper bushings, electronic and electrical components, and high thermal conductivity structural components. Compared to TU2 Oxygen-Free Copper, T2Pure Copperhas relatively higher oxygen content but generally lower material costs, making it suitable for most conventional conductive, thermal, and copper processing scenarios.
By focusing on application scenarios, boundaries of advantages, and non-recommended scenarios, it helps sales, customer service, and quoting staff quickly determine whether the material meets current part requirements.
It has good electrical conductivity, thermal conductivity, good ductility, good weldability, wide material availability, good processing adaptability, suitable for CNC machining and sheet metal stamping, suitable for electrical connection and heat dissipation applications, and generally costs lower than oxygen-free copper and special copper alloys.

The following parameters come from product information and material knowledge fields, used for design review, quotation communication, and preliminary judgment before material selection.
| Material positioning | A general-purpose pure copper material suitable for making conductive parts, thermal components, copper busbar terminals, electrodes, heat dissipation structural components, ordinary precision copper parts, and electronic and electrical connectors. |
|---|---|
| Precision performance | Pure CopperT2 suitable for CNC turning, milling, drilling, tapping, stamping, bending, wire cutting, and partial precision machining. Because copper is relatively soft and has high thermal conductivity, it is prone to knife sticking, burrs, knife marks, surface scratches, and thin-wall deformation during processing. Precision conductive surfaces, heat dissipation contact surfaces, assembly holes, and welded surfaces are recommended to control tolerances and surface roughness separately. |
| Dimensional tolerances | The general dimensional tolerances of CNC machinedPure CopperT2 can be referenced as ±0.02mm-±0.10mm, while ordinary structural parts can be evaluated at ±0.10mm-±0.20mm. The overall dimensional tolerance for stamped, bent, or large-size thin copper plates may be larger. These values are standard reference ranges and do not guarantee absolute tolerances for all structures. Actual values should be confirmed based on part dimensions, wall thickness, processing methods, surface treatment, and assembly requirements. |
| Minimum Wall Thickness | The wall thickness of ordinary CNC machined structures is recommended to be no less than 0.8mm-1.0mm. BecausePure Copperis relatively soft, thin-walled structures are prone to deformation, dents, or machining vibrations. Load-bearing positions, thread positions, welding positions, and large sheet positions should be appropriately thickened. For stamped copper sheets, conductive connectors, or shielding components, thinner sheets can be selected based on current, heat dissipation, assembly, and strength requirements, but deformation and strength must be evaluated. |
| Recommended wall thickness | Standard conductive sheets and connectors are recommended 0.5mm-2.0mm; ordinary CNC copper parts are recommended 1.0mm-3.0mm; heat sinks, conductive blocks, copper busbars, terminals, and the positions bearing assembly force are recommended to be above 2.0mm. Design should be based on current capacity, heat conduction requirements, screw tightening force, and structural strength. |
| Minimum aperture | CNC machining can achieve smaller hole diameters, but thePure Copperis softer, making small and deep holes prone to burrs, tool sticking, and chip removal difficulties. For general designs, the recommended aperture is no less than 1.0mm. It is recommended to reserve space for precision holes, screw holes, positioning holes, and conductive contact holes, and if necessary, drilling, reaming, boring, or deburring are used. |
| Assembly clearance | For precision metal assembly, one side can be reserved at 0.02mm-0.10mm according to fitting requirements; for ordinary plug-in and assembly, it is recommended to reserve 0.10mm-0.30mm per side. If parts require tin, nickel, silver, gold, or anti-oxidation treatments, additional gaps should be reserved according to the thickness of the coating. The conductive contact position should not be too loose; it should be evaluated separately in consideration of contact pressure, surface treatment, and conductivity requirements. |
| Detailed performance | Pure CopperT2 suitable for machining holes, grooves, steps, chamfers, threads, conductive contact surfaces, heat dissipation surfaces, and simple structural details. Because the material is soft, overly fine sharp corners, thin edges, elongated stitches, and tiny text are prone to deformation, burrs, or weakening after post-processing. LOGO, numbering, and markings are recommended to be achieved through laser marking, engraving, etching, or subsequent surface treatment, with key conductive surfaces avoiding excessive texturization. |
| Surface effect | Pure CopperT2 raw surface usually shows a purplish-red or copper-colored metallic texture, with a typical copper appearance. Polishing produces a brighter red copper surface, brushing produces linear metal textures, and sandblasting produces a matte copper finish. Long-term exposure to air gradually oxidizes and darkens, and the surface may appear brown, dark red, or oxidized spots. If long-term appearance and conductivity stability are needed, tin, nickel, silver, gold, or oxidation protection can be applied. |
Based on material characteristics and suitable product ranges, customer needs are broken down into easier application directions to determine.

The core features ofPure CopperT2 are strong electrical and thermal conductivity, along with good plasticity and ductility, making it suitable for electrical connections, heat dissipation, heat conduction, and general copper machining. T2Pure Coppermaterials are relatively soft, with low strength and hardness, and are prone to scratches, dents, deformation, and burrs during processing and transportation. Therefore, they are more suitable for functional conductive electrical and thermal parts rather than high-strength structural or wear-resistant parts.
Based on wall thickness, hole position, assembly clearance, dimensional tolerances, and material usage risks, determine in advance whether the part structure is suitable for T2 Copper.
Post-processing of T2 Copper affects appearance, dimensions, hole position, assembly clearance, and usage validation results, and should be explained in advance during quotation, DFM review, and sample confirmation stages.
Post-processing should focus on appearance display, dimensional fitting, connection assembly, and testing verification. Parts involving assembly positions need to be reserved in advance for machining, coating, and trial assembly allowances.
For common issues such as threads, snaps, strength, temperature resistance, and weather resistance, identify in advance whether the material needs to be replaced or if another processing method should be used.
When customer demand exceeds T2 Copper material boundaries, it is necessary to combine strength, temperature resistance, toughness, long-term stability, and mass production goals to promptly recommend alternative materials or processing technologies.
If higher purity, lower oxygen content, and more stable vacuum or high-temperature welding performance are required, oxygen-free copper TU1 or TU2 can be chosen; If higher strength and wear resistance are required, chromium zirconium copper, beryllium copper, or Brass can be chosen; If better machinability and decorative quality are needed, Brass H59 or H62 can be chosen; If a lightweight heat dissipation structure is needed,6061 Aluminum Alloy or AlSi 10Mg can be chosen; If higher corrosion resistance is required, stainless steel or nickel-plated copper parts can be chosen.
If customers mainly focus on conductivity, thermal conductivity, ordinary copper processing, and cost control, Pure CopperT2 is a very common and suitable choice. If customers require vacuum electronics, high-temperature brazing, low oxygen content, or higher material purity, TU2 Oxygen-Free Copper or TU1 should be prioritized. If customers require high strength, wear resistance, elasticity, or long-term mechanical load-bearing capacity, it is not recommended to prioritize T2Pure Copper; instead, chromium-zirconium-copper, beryllium-copper, Brass, steel, or other structural materials should be considered.
