Graphite rod | Carbon rod

Graphite rod / carbon rod: is an important graphite product. The graphite rod | carbon rod is widely used and has the same superior performance as other graphite products, such as high carbon content, high temperature resistance and good conductivity at high temperature. Therefore, it has good application in both transport industry and energy management industry. At the same time, it is also widely used in its own industry, such as manufacturing graphite electrode, anodes and cathodes, and the application in other industries is to manufacture heating elements, resistors and fluxing agents / degassing tubes, be processed into molds and make graphite crucibles. In addition, it is also widely used in metallurgy, mechanical engineering, chemical and electrochemical industries as special structural parts.   

 

HP Graphite has a powerful capacity of producing graphite rod / carbon rod. For application of different customers, we provide custom-made cut-off sizes to manufacture graphite rod / carbon rod satisfying your requirements. 

Diameter range of products we provide: 50mm----1200mm 

Characteristics of graphite rod | carbon rod 

  • Fine particle: good electrical conductivity and high temperature resistance; it is mainly used in chemical industry and can be custom-made based on customer demand.
