India is the world's second largest producer of natural graphite, but its output of 120000 tons is only one seventh of that of China. In China, it mainly focuses on casting and crucible consumption. The main producing states are Orissa and Rajasthan, Andhra, Bihar, Gujarat and Tamil Nadu, which also produce natural graphite

Graphite mold has many excellent properties, such as high temperature resistance, electrical and thermal conductivity, lubricant, stable chemical properties, strong plasticity, thermal shock resistance and so on. Dongguan Jiecheng New Material Co., Ltd. has formally grasped the advantages of graphite. After several years of growth, it has become a leader in the graphite manufacturing and operation industry. The graphite products it produces are not only complete in variety but also reliable in quality. It has been uniformly praised by domestic manufacturers.

Carbon fiber is a new material with excellent mechanical properties. Its specific gravity is less than 1 / 4 of that of steel. The tensile strength of carbon fiber resin composites is generally more than 3500MPa, which is 7-9 times that of steel. The tensile elastic modulus is 230-430gpa, which is also higher than that of steel. Therefore, the specific strength of CFRP, that is, the ratio of the strength of the material to its density, can reach more than 2000 MPA / (g / cm3), while the specific strength of A3 steel is only about 59 MPA / (g / cm3), and its specific modulus is also higher than that of steel. In this sense, it indicates the broad application prospect of carbon fiber in engineering. Looking at the excellent properties of a variety of emerging composite materials, many people expect that human beings are entering an era of widespread application of composite materials from the era of steel.
