Pure copper T2 is a commonly used grade of high-purity copper, with advantages such as "good electrical and thermal conductivity and high ductility," making it ideal for electrical conductive components and heat dissipation structures.
Quote checklist: Upload your 3D model and, when available, a 2D drawing. Identify the required process, material, quantity, critical dimensions, finish, appearance standard, and target delivery date.
Engineering note: Values below are typical reference ranges. Final manufacturability, tolerances, material condition, surface finish, cost, and lead time depend on the drawing, geometry, quantity, and selected process.
Upload CAD files and mark critical features for an engineering review before production.

Applicable to appearance surfaces and functional contact surfaces; if mirror/fine lines and other targets are required, please indicate the appearance standards and reference samples in the remarks.
Often used for parts that require surface weldability or specific contact characteristics; it is recommended to indicate whether there are coating thickness or area requirements.
Used to improve surface protection and appearance consistency; if there are color/gloss preferences or masking area requirements, please mark them in the drawings/notes.
Used to reduce the risk of discoloration and spots caused by surface oxidation; suitable for delivery scenarios that are more sensitive to appearance stability.
Suitable for model, logo, serial number and other information marks; please provide content, location, direction and acceptable line width/depth requirements.
For structural parts and end-use parts, it supports processing according to drawings and rapid delivery, and is suitable for trial production and small batch iteration.
Polishing, tin plating, nickel plating and anti-oxidation treatment can be selected according to the purpose, taking into account both appearance and functional surface objectives.
Supports laser engraving for model/batch/serial numbers, which facilitates on-site assembly, quality inspection and traceability management.
Upload the file to evaluate process feasibility and lead time; the clearer the critical dimensions and critical surfaces are marked, the faster and more accurate the quote will be.
T2 Copper is suitable for rapid processing and small batch production of structural parts and end-use parts. If you have more specific goals for corrosion resistance, strength, wear resistance or appearance texture, you can upgrade and choose from stainless steel/alloy steel/aluminum alloy and other material systems according to your needs.
It is recommended to provide STEP/STP (3D) + 2D (PDF/DWG/DXF) tolerance markings; if only 3D, please also list the key dimensions, tolerances, surface and finishing requirements (polishing/electroplating/anti-oxidation/radium engraving) in the remarks.
It is recommended to focus on: critical dimensions/tolerances, minimum wall thickness and structural details, and finishing (polishing/tin plating/nickel plating/anti-oxidation/radium engraving). These will directly affect processing hours, fixture strategies and lead times.
Supports polishing. It is recommended that you write clearly in the notes: polishing area (which surfaces), target texture (fine polishing/mirror tendency/retaining fine lines), and whether slight knife marks or color differences are allowed; it is better to have a reference picture.
T2 Copper supports tin plating and nickel plating. When placing an order, please indicate: electroplating type, whether there is a coating thickness/specification, the area that requires electroplating and the shielded area (parts that are not allowed to be electroplated).
Supports anti-oxidation treatment to reduce the risk of discoloration and spots caused by surface oxidation, and is suitable for delivery and storage scenarios that are more sensitive to appearance stability. If you have high requirements for color consistency, it is recommended to state the acceptance criteria in the remarks.
Support laser engraving. Please provide: laser engraving content (text/number/Logo), location, size, direction, and acceptable line width/depth requirements; it is recommended to provide vector files for Logo.
Common impact items include: ultra-thin walls, deep cavities and deep grooves, slender cantilevers, densely packed small holes/small threads, and situations where the appearance requirements are very high but the standards are not clear. It is recommended to mark the key surfaces and acceptable processing texture range in advance.
Delivery time is related to size, structural complexity, quantity and finishing. Polishing, electroplating (tin plating/nickel plating), anti-oxidation treatment and laser engraving will increase the process and schedule; after uploading the file, we will provide a clear lead time and expedited feasibility.
