High purity isostatic pressing graphite blocks
We can provide different specification quality isostatic pressing graphite block.
1) High temperature and oxidation resistance, corrosion resistance, longevity.
2) Applications: casting molds for railroad wheels, heat exchangers for Chemical industries,
electrodes and linings in some industrial furnaces.
• Definition
High purity carbon isostatic pressing graphite is a new type of material. High purity carbon isostatic pressing graphite is used in precision tool,aerospace industry ,war industy ,chemical industry.ect .They are of high-strength ,high purity,low resisticity ,resistance to high temperature ,good resistance to shake and oxidation ,and tend to be processed elaborately.
1. High density high purity carbon isostatic graphite.
2.superior compact structure, good electrical and thermal conductivity, high resistance to oxidatio.
• Characteristic
High density, fine grain size, high purity, low specific resistance and high strength with ease of precise machining. Also features include excellent thermal shock properties, high temperature and oxidation resistance with good anti-corrosion.
• Application
It is widely used for EDM machining, mould for sintering diamond, crystallizer for horizontal continuous casting, crucible for melting nonferrous metal, industrial furnace, heating element in vacuum furnace, etc.
