Product application industry:
7N copper has significant advantages in the superconducting industry due to its low resistivity, high thermal conductivity, excellent processability and extremely low impurity content. It can reduce energy loss, improve heat dissipation efficiency, avoid impurities interfere with superconducting performance, and enhance composite materials. The mechanical strength and thermal stability of the machine can reduce the magnetoresistance effect in low temperature environments, so it is widely used in the manufacturing of superconducting cables, magnets and other key equipment.
The extremely high purity of 7N copper effectively reduces interference from impurities during semiconductor deposition, ensuring high quality and consistency of film materials. Low impurity content helps to form a more uniform and denser copper film, improves electrical and mechanical properties, and meets the strict requirements of advanced semiconductor devices for material performance. The high conductivity of 7N copper promotes efficient migration of electrons in semiconductor devices, improving the overall performance and response speed of the device. When copper targets are used in physical vapor deposition (PVD) and other processes, high conductivity reduces energy loss and improves deposition efficiency。
7N can quickly conduct and disperse the generated heat, prevent the equipment from overheating and ensure the stable operation of the system under high temperature environment. The high purity of 7N copper reduces impurities, significantly improves corrosion resistance, and adapts to variable and harsh environmental conditions in aerospace, such as high humidity, high salt and extreme temperatures. In a highly corrosive environment, 7N copper can effectively prevent material deterioration, extend the service life of equipment and components, and reduce maintenance costs.
7N copper has very superior electrical conductivity, almost close to ideal conductive materials, with conductivity up to 101% IACS (International Conductivity Standard). This means that 7N copper has extremely low energy loss during electrical transmission, so it has unique advantages in applications such as high-frequency circuits and microelectronic components that require efficient energy conduction. The ultra-high purity of 7N copper makes it show extremely high chemical stability during long-term use, with almost no impurities. This stability is crucial for high-precision electronics。
The extremely high purity of 7N copper ensures that variable interference caused by impurities is reduced in scientific research experiments, and improves the accuracy and reliability of experimental results. The low impurity content ensures consistency in the performance of the material and facilitates repetitive experiments and standardized research. In experiments requiring high-precision electrical measurements and signal transmission, 7N copper provides stable and efficient conductivity, reducing signal loss and noise.
7N copper has extremely high thermal conductivity, which can quickly conduct and distribute heat generated by electronic equipment effectively, prevent equipment from overheating and ensure stable operation of the system. Uniform heat conduction performance helps optimize the heat distribution inside the equipment, reduce the formation of hot spots, and improve overall heat dissipation efficiency. 7N copper has good ductility and toughness, which is easy to process into complex radiator shapes, meeting the design needs of various equipment.
