 High temperature conductive putty is a kind of material with excellent electrical conductivity. It is usually made of metal atomic powder sintered at high temperature, with high thermal stability and thermal conductivity, and can maintain good electrical conductivity under extreme conditions. In high temperature environment, high temperature conductive putty can conduct electricity stably and is not easy to increase resistance sharply or burn out, so it is widely used in high temperature electronic devices, high temperature sensors and other fields. At the same time, the surface of high-temperature conductive putty usually has good oxidation resistance, which can effectively resist oxidation damage and improve its service life in high-temperature environment. In general, high-temperature conductive putty has excellent electrical conductivity and thermal stability, and is an ideal high-temperature conductive material.
