High temperature resistance: The melting point of graphite is 3850±50℃, and the boiling point is 4250℃. Even if burned by ultra-high temperature arc, the weight loss is very small.
It has high mechanical strength: The strength of graphite increases with temperature below 2500°C. At 2000°C, the strength of graphite doubles and can withstand greater working pressure.
It has excellent electrical and thermal conductivity: The electrical conductivity of graphite is one hundred times higher than that of general non-metallic minerals, and its thermal conductivity is higher than that of metal materials such as steel, iron, and lead. Its thermal conductivity is hundreds of times larger than that of general non-metallic materials. The steel is twice as big, and the good thermal conductivity makes the heat transfer even when the whole mold is working.
Thermal shock resistance and thermal expansion coefficient: Graphite can withstand drastic changes in temperature without being damaged when used at room temperature. When the temperature changes suddenly, the volume of graphite will not change much and cracks will not occur.
》According to product usage, graphite molds are divided into graphite electrodes, carbon blocks, graphite anodes, carbon electrodes, pastes, electric carbons, carbon fibers, special graphites, graphite heat exchangers, etc.
》According to the processing depth, graphite molds can be divided into carbon products, graphite molds, carbon fibers and graphite fibers.
》According to different raw materials and production processes, graphite molds can be divided into graphite molds, carbon products, carbon fibers, special graphite molds, etc.
》According to the ash content, graphite molds can be divided into more ash products and less ash products.
