Professional Graphite Block Manufacturer
We are a professional Graphite Block Manufacturer. Our products are strictly in accordance with international and industry standards. Shaped graphite blocks can be customized according to specific geometry and material requirements.
Main materials: Isostatic graphite, High strength and purity graphite, Fine structure graphite.
Properties of graphite block:
1) High temperature resistance:
Melting point 3850 ± 50 ℃, boiling point 4250 ℃. Even if burned by ultra-high temperature electric arc, the weight loss and thermal expansion is very small. Graphite block strength increases with increasing temperature, at 2000 ℃ the strength is doubled.
2) Electricity and thermal conductivity:
Graphite has 100 times conductive than non-metallic mineral and more thermal conductivity than steel, iron, lead and other metal materials. Thermal conductivity decreases with increasing temperature, at very high temperatures, graphite block becomes thermal insulator.
Graphite lubrication depends on the size of graphite scales, the greater scale, the better lubricating.
4) Chemical stability:
Graphite has good chemical stability at room temperature, resists to corrosion of acid, alkali and organic solvents.
Graphite toughness is good, can be crushed into thin slices.
6) Thermal shock resistance:
Graphite at room temperature can withstand the dramatic changes in temperature without damage. In temperature sudden changes, no volume change, no cracks.
