Sell Graphite Dies

Description

Graphite die is use for continuous casting of copper alloy, precious metals and cast iron.

The graphite “die” permits:
_ the shaping of the metal,
_ the heat extraction necessary to transform the metal from liquid to solid state.

Material: Graphite 
Special features: High purity, fine grain, good performance of electrical conductivity and thermal conductivity, high density, good corrosion resistance, thermal shock resistance, thermal stability, high mechanical strength, low permeability, and good oxidation resistance 
The raw material is capable of producing various semiconductor molds and radio tube
