With the rapid development of industries in China such as metallurgy, chemicals, machinery, medical devices, nuclear energy, automotive, and aerospace, the demand for graphite and carbon products in these sectors will continue to rise. China’s graphite and carbon product industry is set to maintain rapid growth. Based on Xinerda’s 30 years of experience in processing graphite products, it is clear that the reason why graphite products enjoy market trust lies primarily in their technical properties. Let’s take a look at them today: 1. High temperature resistance: Graphite products are among the materials with the highest known resistance to high temperatures. Its melting point is 3850°C ± 50°C, and its boiling point reaches 4250°C. Under an ultra-high-temperature arc of 7000°C for 10 seconds, it exhibited the least graphite loss, with a weight-based graphite loss of 0.8%. It can be seen that graphite has excellent high-temperature resistance. 　　2. Thermal and electrical conductivity: Graphite products possess good thermal and electrical conductivity. Compared to ordinary materials, its thermal and electrical conductivity is quite high. It is 4 times higher than stainless steel, 2 times higher than carbon steel, and 100 times higher than ordinary non-metals. 　　3. Special thermal shock resistance: Graphite products possess excellent thermal shock resistance; that is, when temperatures change suddenly, their coefficient of thermal expansion is low, granting them good thermal stability. As a result, cracks do not form during sudden changes in temperature. 　　4. Chemical stability: Graphite products exhibit good chemical stability at room temperature, resisting corrosion from acids, alkalis, and organic solvents. 　　5. Lubricity: The lubricating properties of graphite products are similar to those of molybdenum disulfide, with a friction coefficient of less than 0.1. Their lubricating capacity varies depending on the size of the flakes; the larger the flakes, the lower the friction coefficient and the better the lubricity.
