PRODUCT SPECIFICATIONS AND DETAILS
Product Overview
Graphite Block is a solid graphite material supplied in block form for machining, thermal processing, metallurgical applications, and industrial component manufacturing. Compared with graphite paper or graphite sheet, graphite block is a more structural graphite product designed for load-bearing, machining, shaping, and use in demanding high-temperature or chemically aggressive environments.
Depending on the raw material route and manufacturing process, Graphite Block can be produced as molded graphite, extruded graphite, vibration-molded graphite, or isostatic graphite. At QDZRT Graphene, different grades are available according to density, purity, grain size, strength, electrical resistivity, thermal conductivity, and end-use requirements. Graphite blocks are widely used in EDM electrodes, furnace components, molds, crucibles, semiconductor parts, metallurgical fixtures, chemical equipment, and customized graphite machined parts.
