graphite block,graphite material,graphite ,ultrafine grain graphite

1.graphite ultrafine grain with the average granulity 16μm

2.high-temperature resistance, toughness

3.thermal conductivity low resistivity. 

Its application areas cover colored metal and lanthanon metal smelting, and heat up appliance, crystallizer, heat insulation board and precision mould. And it is especially good for EDM graphite electrode, as it provides faster discharging ability and more even electric current.
