1.Applications

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

- Sintering molds for cemented carbides and diamond tools.

- Sintering molds for electronic components.

- Electrodes for EDM.

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

- Bearings and seals in pumps, turbines and motors.

- and so on.

 

2.Programmable properties 

- Fine grain

- Homogeneous structure

- High density

- Excellent thermal conductivity

- High mechanical strength

- Proper electrical conductivity

- Minimum wettability to molten metals
