Graphite gasket is a sealing element made of flexible expanded graphite as the base material, which has excellent comprehensive properties such as high temperature resistance, corrosion resistance, softness and compressibility. Its biggest feature is that it can maintain a long-term stable sealing effect under extremely harsh working conditions. Copper gasket has many significant performance characteristics and is suitable for sealing occasions with high temperature, high pressure and requirements for thermal conductivity and electrical conductivity. DESCRIPTION Copper gaskets are made of metal materials such as red copper or copper. They have good ductility and flexibility. After being preloaded, they can fit the sealing surface well, thus forming a reliable seal. Due to the excellent thermal conductivity of copper, it is often used in occasions that require rapid heat dissipation, such as engine systems, heat exchanger interfaces, etc. Copper gaskets have excellent high temperature resistance and can generally work stably in environments up to 650℃. They are suitable for sealing media such as steam, hot oil, and compressed gas. At the same time, copper itself also has good corrosion resistance and can resist erosion by water, steam, certain organic solvents, and weak acids and alkalis. Mechanical strength is another major advantage of copper gaskets. Compared with non-metallic sealing materials, copper gaskets are not easily squeezed and deformed and can withstand higher working pressures.
