TU2 copper sheet is a high-purity oxygen-free copper material known for its excellent electrical and thermal conductivity. Due to the extremely low oxygen content, the oxide film formed when it is heated is dense and not easy to peel off, giving it excellent processing performance, welding performance, corrosion resistance and cold resistance. These characteristics make TU2 copper sheet has a wide range of applications in electronic vacuum instrumentation, conductive connectors and other fields.
TU2 copper sheet not only has high purity, its excellent physical properties and processing characteristics also make it an ideal choice for many industrial fields. Whether it is the requirement of strict electrical conductivity, or the need to withstand the harsh environment of corrosion resistance, TU2 copper sheet can meet the requirements and show excellent performance.
