High temperature resistance: carbon graphite has excellent high temperature resistance and can maintain stability for a long time. Generally, it can be used at high temperatures from 3000 ℃ to 3600 ℃, but its thermal expansion rate is very small, and it is not easy to deform at high temperatures.
Corrosion resistance: carbon graphite can resist the erosion of various corrosive media. Because of its good chemical stability, it can be compatible with many organic and inorganic acids, alkalis and salts without corrosion or dissolution.
Conductivity and thermal conductivity: carbon graphite is a good conductor with good conductivity and thermal conductivity. Therefore, it is widely used in electrofusion and electrochemical machining.
Low friction coefficient: carbon graphite has low friction coefficient, so it is often used to make sliding materials or parts.
Heat exchanger: The heat exchanger made of carbon graphite is an efficient heat exchanger, which can be used in chemical, electric power, petrochemical and other fields. It has good corrosion resistance and efficient heat transfer performance.
Electrode material: carbon graphite electrode is mainly used in metallurgy and chemical industry, and can be used in high temperature, high pressure and corrosive applications such as electric arc furnace and electrolytic tank.
Heat transfer plate: carbon graphite heat transfer plate is a kind of efficient heat transfer material, which can be used to manufacture high-power LED, energy-saving lamp, solar panel, nuclear reactor and other fields.
Mechanical seal material: carbon graphite mechanical seal material has good wear resistance, corrosion resistance and low friction coefficient, and can be used to manufacture sealing materials and other high-end mechanical parts.
Carbon graphite heat pipe: carbon graphite heat pipe is an efficient heat pipe material, which can be used to manufacture high power electronic components, electrical radiator and other fields.
In short, as a high-end industrial material, carbon graphite has many excellent properties and wide application fields. With the development of science and technology and the continuous expansion of application, carbon graphite will play an increasingly important role in the future.
