Due to the carbon rods use high temperature easy conductive good chemical stability. Has been widely used in national defense, machinery, metallurgy, chemical, casting, non-ferrous metal, light, and other fields, the nine is black carbon rod, is also used as ceramic, semiconductor, medical, environmental protection, laboratory analysis and other fields, become the most widely used non-metallic materials today. When cutting steel, do not need to use like oxygen - acetylene flame cutting is flammable, explosive gas, low cost and operation safety. Can use the method of arc cutting processing a variety of can not use gas cutting processing of metal, such as cast iron, stainless steel, copper, aluminum, high efficiency, and can get ideal effect. Carbon rods can also be used for aluminum hot metal mixing water, oxidation resistance, corrosion resistance.
