The vacuum pump graphite scraper requires high material density, small particle size,and low expansion coefficient.Changrui's fine-grained high-purity graphite has a melting point of 3850 ± 50°C and a boiling point of 4250°C. Even if it is burned by ultra-high temperature arc, the weight loss is very high It has a small coefficient of thermal expansion and a small coefficient of thermal expansion. The strength of graphite increases with increasing temperature.

Gold melting crucible, professionally used in jewelry casting industry, mainly used for gold melting and silver melting casting.

Changrui graphite uses aluminum phosphate graphite material with excellent oxidation resistance, anti-oxidation coating and anti-oxidation protective sleeve which are not harmful to the melt, and introduces advanced anti-oxidation technology from the United States and optimizes , Specializing in the development of composite long-life isostatic graphite rotors, baffles and other products.

The graphite mold materials used in the manufacture of diamond tools are mainly ultra-fine particle structures, high purity, and high degree of graphitization. The average diameter of the graphite mold material is less than 15 microns, or even less than 10 microns, and the average pore diameter is less than 2 microns. The graphite mold made of the carbon raw material has the advantages of small porosity, dense structure, high surface smoothness, and strong anti-oxidation ability.
