Graphite GradesProperties of Graphite Materials
The fine grain graphite grades are typically available in smaller cross sections than the medium grain graphite grades This is because fine grain graphite grades are very dense and highly engineered products To maintain the material properties and design characteristics these materials are processed in smaller cross sectional blocks
