Product Overview
The purple copper square plate is the flagship metal sheet product supplied by Wenzhou Dongya Trading Company. It is made from standard electrolytic copper, laser-cut, and forms into a square, flat copper plate.
Red copper possesses excellent electrical conductivity, thermal conductivity, and ductility. Its antioxidant and corrosion-resistant properties are superior to those of brass and aluminum. Our purple copper square plates have a smooth and flat surface, free of cracks, black spots, or internal porosity. They can be directly processed for secondary operations such as bending, stamping, rotation, welding, and etching.
This product is widely used in various fields such as power conductive busbars, new energy battery connection plates, mold cooling base plates, vacuum equipment electrodes, chemical corrosion-resistant linings, and precision instrument conductive components. Dongyao Trading can customize products with any length, width, and thickness according to customer drawings, and also offers processing services such as cutting, deburring, polishing, and applying an anti-oxidizing coating.
Product Features
1. Ultra-high purity raw materials: Copper content ≥ 99.90%. Minimal loss during electrical and thermal transmission.
2. High-quality, flat surface: The product, which has undergone rolling and annealing processes, has a smooth surface free of pores, layers, or oxidation spots, and does not exhibit cracking during deep processing.
3. Exceptional processing properties: The soft texture is suitable for bending, deep stamping, and CNC turning processes. There are no signs of breakage after cold forming.
4. Natural corrosion- and oxidation-resistant properties: Pure copper surfaces form a passive protective layer, which provides a long lifespan in air and environments with weak acids and bases.
Complete Product Information
1. Raw materials and processes for production
The raw materials are chosen of high-quality copper to eliminate the recycling of impure copper alloys;
Process: Electrolytic copper smelting ingot → hot rolled rough cut → multiple stages of cold rolling → vacuum refilling and softening → precision cutting → circular cutting → surface polishing / coating finished product, full-time numerical control equipment controls dimensional accuracy.
2. Applicable use scenarios
Electric and electrical: conductive gaskets, flow drains, electrode terminals, switching conductive parts;
New energy industry: lithium battery connectors, energy storage and heat storage substrates, photovoltaic conductive accessories;
Mechanical molds: mold heat dissipation pads, injection molding cooling pads, vacuum sealed flanges;
Chemical corrosion prevention: lining of corrosion-resistant equipment, heat exchange plate of acid-base medium;
Hardware processing: jewelry stamping, precision gaskets, electrical conductive components for instrumentation.
3. Quality Control and Testing
Each batch of products comes with the original material list and supports third-party spectroscopic testing;
Before leaving the factory, it completes the appearance detection of the plate surface, the conductivity test, and the thickness and size test.
The three core indicators of copper purity, oxygen content and hardness are strictly controlled, and substandard products are not released from the warehouse.
4. Packaging and Transportation
Small cut samples: waterproof and rustproof oil paper parcel + cardboard wrapper;
The entire large round board: multiple layers of rust-proof film wrap + border protectors to prevent bumps;
Wenzhou warehouse delivers goods, supports logistics, express delivery, whole car freight, can be distributed throughout the country, and export can be made into wooden box fumigation packaging.
6. After-sales service, samples and payment settlement
Sample service: supports small sample cutting free of charge (only a small freight charge), and can send samples for testing materials first;
After-sales guarantee: Material irregularities, dimensional errors exceeding specifications are returned unconditionally, and the technical team provides guidance on machining selection.
Settlement methods: Online platforms secure transactions, offline transfers to the public, high-volume orders can negotiate accounting periods, and support the issuance of VAT-specific invoices.
Enterprise qualifications: Wenzhou Dongyao Trading has formal business qualifications, non-ferrous metals operating licenses, and can provide enterprise business licenses, material testing reports, export customs information.
