Graphite blocks are made from domestic petroleum coke, and contain more than 99% carbon. We have vibrational, moulded and isotropic graphite blocks. We can machine specific shapes based on the customer's requirements.
In general, it can be divided into extruded graphite blocks/ extruded graphite squares, molded graphite blocks/ molded graphite squares, iso-static graphite blocks|graphite squares.
According to different particle sizes, it can be divided into fine particle graphite blocks/ graphite squares, medium-coarse particle graphite blocks/ graphite squares, coarse particle graphite blocks/ graphite squares.
Graphite blocks/ graphite squares have a wide range of applications, such as for making molds (EDM), and the application of graphite blocks/ graphite squares in other manufacturing industries is also quite extensive.
