Zhejiang Jingliang Copper-Tube Products Co., Ltd

Wholesale High-Purity (99.99%) Cu

High-Purity (99.99%) Cu

-- Steady & Reliable Manufacturer --

The Benchmark for Ultra-Conductive Metallurgy

High-Purity Copper, often referred to as 4N (Four Nines) or C10100, represents the pinnacle of copper refining technology. At Zhejiang Jingliang, our high-purity copper is produced through a multi-stage "Electrolytic Refining" process that meticulously removes trace impurities like sulfur, silver, and iron down to levels below 10 parts per million (ppm). In the world of high-end electronics and scientific research, even the slightest impurity can increase electrical resistance and generate unwanted heat. By achieving 99.99% purity, we offer a material with the highest possible electrical and thermal conductivity of any commercial copper. This is the material of choice for "Super-Premium" applications where precision is the only metric that matters.

Our 99.99% Cu is processed in "Vacuum Induction Furnaces" to prevent atmospheric contamination during melting. This results in a material with "Zero Oxygen" and exceptionally low hydrogen content, making it ideal for "Sputtering Targets" and vacuum-sealed electronics. The crystal structure of our high-purity copper is engineered to be extremely uniform, which is critical for "Acoustic Transmission" in high-fidelity audio cables and "Cryogenic Stability" in quantum computing components. At Jingliang, we verify our purity using "Inductively Coupled Plasma" (ICP) mass spectrometry, providing our clients with a "Chemical Fingerprint" of every batch. Whether you are building the next generation of semiconductors or a high-performance particle accelerator, our 4N copper provides the "Purest Path" for energy and signal transmission.

Semiconductors, Quantum Computing, and High-End Audio

High-purity (99.99%) copper is the essential material for "Semiconductor Metallization" and "Microchip Interconnects," where low resistance is vital for processing speed. In "Quantum Computing," it is used for thermal links and microwave shielding because of its predictable performance at millikelvin temperatures. "High-End Audio Manufacturers" utilize 4N copper for "Audiophile Cables" to ensure signal purity and minimize phase distortion. It is the primary choice for "Sputtering Targets" in the thin-film coating industry. In "Aerospace and Defense," it is used for high-precision sensors and radar components. It is also found in "Medical Imaging" (MRI and CT scanners) where high-purity magnets are required. Additionally, it serves as the base for "High-Power Vacuum Tubes" and "Cryogenic Heat Sinks" in laboratory research equipment where thermal bottlenecks must be eliminated.

Minimum Resistance and Maximum Thermal Flow

The primary advantage of 4N copper is "Superior Electrical Conductivity" (over 101% IACS), which "Reduces Power Losses" and heat generation in sensitive electronics. Its "Ultra-Low Oxygen Content" prevents "Hydrogen Embrittlement" during high-temperature processing, making it safer for advanced brazing and welding. Our 99.99% Cu offers "Exceptional Crystal Uniformity," which provides "Consistent Signal Velocity" in telecommunications and audio applications. The "Vacuum Grade Purity" ensures that there is "Zero Outgassing" when the material is used in space or laboratory vacuum chambers. This "Protects Sensitive Instruments" from contamination. The material is also "Highly Ductile," allowing it to be drawn into ultra-fine wires (as thin as human hair) without breaking. Finally, the "Unrivaled Thermal Performance" allows for more "Efficient Heat Dissipation" in high-power laser and computing environments, "Extending the Lifespan" of critical digital components.

Clean-Room Packaging and Technical Assurance

High-purity copper is a premium technical product. We ship it in "Vacuum-Sealed Double-Bagged Packaging" to prevent surface oxidation and atmospheric contamination. Payment is 30% T/T and 70% L/C. We ship from Ningbo/Shanghai, providing a "Certificate of Analysis" (CoA) for every single lot, listing all trace impurities in ppm. For high-tech industries, we offer "Clean-Room Loading" and "Nitrogen-Purged" shipping containers to maintain the 4N integrity from our factory floor to your laboratory or fabrication facility.

  • Q: What is the difference between ETP and 99.99% copper?
  • A: ETP (99.9%) contains oxygen and trace impurities that increase resistance. 4N copper is oxygen-free and refined further to achieve the highest possible conductivity and vacuum stability.
  • Q: Is 4N copper harder than standard copper?
  • A: No, actually, high-purity copper is generally "Softer and More Ductile" than ETP copper, making it easier to draw into fine wires.
