Applications of high purity casting graphite block:

1.Molds, chutes, sleeves, sheathes, linings, etc. in continuous casting systems for making shaped steel, cast iron, copper, aluminum.

2. Sintering molds for cemented carbides and diamond tools.

3.Sintering molds for electronic components.

4.Electrodes for EDM.

5.Heaters, heat shields, crucibles, boats in some industrial furnaces (such as furnaces for pulling monocrystalline silicon or optical fibers).

6. Bearings and seals in pumps, turbines and motors.and so on.

Properties of high purity casting graphite block:

Fine grain

Homogeneous structure

High density

Excellent thermal conductivity

High mechanical strength

Proper electrical conductivity

Minimum wettability to molten metals

Typical size of high purity casting graphite block:
