Specialty graphite blocks and rounds
 
 
high density machinable graphite block for fabrication high density machinable graphite blocks and graphite rounds high density graphite round for machining
 
Our fine grain extruded, molded and isotropic graphite block & round products have four grain sizes. This graphite has homogenous qualities which makes our graphite blocks and graphite rounds easy to machine. Our graphite has similar physical characteristics as the major US suppliers. We strive to provide superior pricing, warehousing and service without sacrificing quality. We stand behind our products or your money back.
