Product application industry:
Ultra-high purity copper offers significant advantages in the superconductivity industry due to its low resistivity, high thermal conductivity, excellent workability, and extremely low impurity content. It helps reduce energy loss, improve heat dissipation efficiency, avoid impurities interfering with superconducting performance, and enhance the mechanical strength and thermal stability of composite materials. Additionally, it minimizes magnetoresistance effects in low-temperature environments. As a result, it is widely used in the manufacturing of superconducting cables, magnets, and other critical equipment.
Semiconductor Targets:
The extremely high purity of ultra-high purity copper effectively minimizes interference from impurity elements during semiconductor deposition processes, ensuring high quality and consistency of thin-film materials. Low impurity content contributes to the formation of more uniform and denser copper films, improving electrical and mechanical properties to meet the stringent material performance requirements of advanced semiconductor devices. The high electrical conductivity of ultra-high purity copper facilitates efficient electron migration within semiconductor devices, enhancing overall performance and response speed. When used in copper targets for processes like physical vapor deposition (PVD), high conductivity reduces energy loss and improves deposition efficiency.
Aerospace & High-End Manufacturing:
Ultra-high purity copper rapidly conducts and dissipates generated heat, preventing equipment overheating and ensuring stable system operation in high-temperature environments. Its high purity reduces impurity content, significantly enhancing corrosion resistance and enabling adaptation to the variable and harsh conditions of aerospace applications, such as high humidity, high salinity, and extreme temperatures. In highly corrosive environments, ultra-high purity copper effectively prevents material degradation, extends the service life of equipment and components, and reduces maintenance costs.
New Energy Technologies:
With its electrical conductivity approaching the theoretical limit of pure copper, ultra-high purity copper enables highly efficient power transmission in new energy systems. This not only reduces energy loss but also improves overall system efficiency, making it particularly suitable for power transmission paths in solar inverters, wind power systems, and electric vehicles. New energy equipment, such as electric vehicle batteries and solar panels, often faces heat dissipation challenges. The high thermal conductivity of ultra-high purity copper ensures rapid and effective heat conduction and dissipation, preventing equipment overheating, extending component lifespan, and enhancing system stability and performance.
The electrical conductivity of ultra-high purity copper is exceptionally superior, nearly approaching that of an ideal conductive material, with a conductivity rating as high as 101% IACS (International Annealed Copper Standard). This means ultra-high purity copper exhibits extremely low energy loss during electrical transmission, giving it unique advantages in applications requiring efficient energy conduction, such as high-frequency circuits and microelectronic components. The ultra-high purity of this copper ensures exceptional chemical stability over long-term use, with virtually no impurity-related effects. This stability is crucial for high-precision electronic products.
The extremely high purity of ultra-high purity copper minimizes variable interference caused by impurities in scientific experiments, improving the accuracy and reliability of experimental results. Low impurity content ensures consistent material performance, facilitating repeatable experiments and standardized research. In experiments requiring high-precision electrical measurements and signal transmission, ultra-high purity copper provides stable and efficient conductive performance, reducing signal loss and noise.
The extremely high thermal conductivity of ultra-high purity copper allows it to quickly and effectively conduct and dissipate heat generated by electronic devices, preventing overheating and ensuring stable system operation. Its uniform thermal conduction properties help optimize heat distribution within equipment, reducing the formation of hot spots and improving overall heat dissipation efficiency. Ultra-high purity copper also exhibits good ductility and toughness, making it easy to process into complex heat sink shapes to meet the design requirements of various devices.
