Product Overview
Description
Product details
Fine grain graphite rod material is made of high quality calcined petroleum coke and modified coal adphalt through the specific process formula and thermal process,but the maximum particle size is only 0.8mm,is a kind of structural material.
Fine grain graphite rod material is mainly used to machine the graphite product used in the high-temperature or corrosion enviroment.The product’s surface is smooth and delicate after processing,the mechanical property is good.
Product specification,size and tolerance can be machined according to the customer’s actual demand.

Fine grain graphite rod material
High temperature resistance, good electrical conductivity, not easy to break, suitable for metal cutting into the shape of a meets the requirements.Graphite rod used in high temperature vacuum furnace heating body, the highest temperature can reach 3000 ℃, is easy to be oxidized at high temperature, in addition to vacuum, can only be used in the neutral atmosphere and reducing atmosphere. Its smaller thermal expansion coefficient, thermal conductivity, resistivity (8 ~ 13) x 10-6 Ω m., good workability with SiC, MoSi2 rods, high temperature resistant, resistant to extreme cold hot sex good, price is cheap.
