Medium coarse graphite

Brief introduction to produpts

The maximum grain size of our extruded graphite is 0.5mm &0.8mm. With advanced technology and our own experiences, we become the first one in China to use extrusion technology to develop this new carbon material. The structure and technical data of our product is completely diffetrent from vibration and molded graphite,and its specification has reached the international advanced level of extruded graphite.

Extruded graphrte has better properties compared with ordinary graphite, like suitable electric resistivity,homogeneous structure, chemical corrosion resistance, antioxidant properties, high temperature stability. It could work in various harsh environment of high temperature and maintain the desired mechanical strength.

Available sizes:

Rods:dia.169-500x Max.2600mm

Blocks:400 x 400 x Max.2400mm, 500 x 300 x Max.2400mm
