We offer a range of Isostatic Graphite products and grades for various applications. High purity graphite materials with ash content as low as 50 ppm, and Non-Oxidizing treated materials are available.
The following isostatic graphite UMC-15 and UMC-35 Grades are made with very fine grain sizes, increasing strength and density. UMC Isostatic graphite materials are alternatives for many cold pressed grades used in continuous casting dies, crucibles and heating elements. UME-15 and UME-35 are used for EDM roughing and finishing work. UMS-35 is a superior grade for many sintering applications.
