Advantage
1. Excellent thermal conductivity and conductivity.
2. Low coefficient of linear expansion, good thermal stability and heat shock resistance.
3. Chemical corrosion resistance is not easy to react with most metals.
4. The strength increases with the increase of temperature at high temperature (above 800 ℃).
5. Good lubrication and wear resistance.
6. Easy to process, good mechanical processing performance, can be made into shape Complex and high precision mould.
