Specifications
High Density Graphite Block on Graphite Block : melting point of graphite is 3850 C , boiling point is 4250 C, small loss even under high temp burning.
1. High Density Graphite Block has its unique advantages: low resistivity, high temp proof, anti corrosion, good thermal shock resistance, electrical conductivity, low coefficient of thermal expansion, self -lubricating, suitable for precise process.
2. Carbon Graphite Block : melting point of graphite is 3850±50C , boiling point is 4250C, small loss even under high temp
burning,low coefficient of thermal expansion. Graphite becomes stronger as temp increases, strength enhances double at 2000°C.
