Molded Graphite Blocks Carbon Blocks is made from the domestic petroleum coke and widely used in the metallurgy, machinery, electronics and chemical industry, etc. The graphite block include molded, extruded, vibrated and isostatic. Our main and most preponderant graphite plate is vibrated formed. Our products own the following characteristics: low electric resistance, good electric and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy and so on



Advantages of Molded Graphite Blocks Carbon Blocks
High temperature resistence.
Perfect thermal resistance property.
Excellent electrical conductivity and thermal conductivity.
Good lubrication.
Strong chemical stability
Low electric resistance
