In the current landscape of global industrial transformation, the demand for 99.9% Pure Copper Sheets has transcended basic electrical plumbing. As a premier OEM Pure Copper Sheet Supplier, Sichuan Kepai New Materials Co., Ltd. recognizes that high-purity copper is the literal backbone of the "Green Revolution." From the intricate busbars in New Energy Vehicles (NEVs) to the heat dissipation modules in AI supercomputing clusters, the metallurgical integrity of copper defines the efficiency limit of modern technology.
We are witnessing a paradigm shift where "copper purity" is no longer just a specification but a critical safety and performance metric. 99.9% purity (often categorized as C11000 ETP or C10100 OFE) ensures minimal electrical resistance, preventing parasitic energy loss and catastrophic thermal runaway in high-voltage applications. As global exporters, we provide the Information Gain necessary for engineers to choose materials that meet both IATF 16949 automotive standards and stringent RoHS environmental compliance.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private company specializing in R&D, production and sales of high conductivity and high strength free cutting tellurium copper and other special copper alloys.
Year of Establishment
Operating from a massive 29,000 square meter facility, we combine traditional craftsmanship with AI-driven production monitoring to ensure every sheet meets international tolerances.
Factory Floor Space (sqm)
With over 30 patent certificates, we don't just follow industry standards; we set them. Our R&D team focuses on "Oxygen-Free" technology to eliminate hydrogen embrittlement.
Patent Certificates
Our 99.9% pure copper sheets are utilized in solar inverters and wind turbine transformers. In regions like the EU and North America, our products support the transition to decentralized power grids, providing the thermal stability required for 24/7 energy harvesting.
Copper wire and sheets are ideal for aerospace applications, especially for generators and data transmission parts. We provide vacuum-melted high-purity copper that withstands the extreme pressure and temperature cycles of orbital flight.
Copper has bactericidal, anti-inflammatory, and antioxidant effects. Our sheets are supplied to medical device manufacturers for use in MRI shielding and antimicrobial touch surfaces in hospital environments.
We understand that a 99.9 Pure Copper Sheet Exporter must navigate complex regional regulations. Kepai provides full documentation for ISO 9001:2015, ISO 14001:2015, and OHSAS 45001:2018. Whether you are in the Southeast Asian manufacturing hub or the European industrial heartland, our localized logistics and compliance teams ensure that all metallurgical certifications (Mill Test Reports) accompany every shipment, guaranteeing traceability and quality assurance.
C19160 (CuNiSiCr) is a high-performance copper alloy belonging to the nickel-silicon precipitation strengthened category. It possesses high strength, excellent conductivity, and outstanding softening resistance.
An engineering material that achieves a perfect balance of excellent cold forming properties and moderate cost. Ideal for deep drawing, stamping, and complex forming.
A typical tin-phosphorus bronze (CuSn4) high-performance elastic alloy. Copper-based with added tin and phosphorus for enhanced wear and corrosion resistance.
Provides the highest strength of all available copper-beryllium alloys. Tensile strength can exceed 200 ksi (1380 MPa) while maintaining superior thermal conductivity.
In high-speed development fields such as NEVs and precision electronics, traditional tellurium copper materials often face conductivity dilemmas. Our OFT variant provides the ultimate solution for high-current applications requiring free-machining properties.
