Graphite Die Casting

Feature of Graphite Die Casting1) High Temperature type: Graphite melting point of 3850 ± 50 , the boiling point of 4250 , even with super-high temperature arc ignition, a small weight loss, a small thermal expansion coefficient. Graphite intensity with the temperature increase to strengthen in 2000 , graphite strength doubled.

2) electrical conductivity, thermal conductivity: the conductivity of the graphite non-metallic ore than a hundred times higher. Thermal conductivity of more than steel, iron, lead, metal materials. Thermal conductivity decreases with increasing temperature, and even at very high temperatures, graphite-insulator.

3) lubrication: graphite flake graphite lubricating properties depend on the size of the greater scale, the smaller the coefficient of friction, lubrication performance better. 4) chemical stability: graphite at room temperature with good chemical stability, to acid, alkali-resistant and corrosion-resistant organic solvents.

5) plasticity: Graphite good toughness, Ningcheng thin flakes. 6) thermal shock resistance: graphite at room temperature when used be able to withstand the dramatic changes in temperature without damage, mutation temperature, the volume of graphite little change, will not have a crack.
