The performance of graphite mould

时时彩5星技巧 www.ugrvh.com   时时彩5星技巧Small make up to tell youThe performance of graphite mould


  1. Good thermal conductivity and electrical conductivity.



  2. Low coefficient of linear expansion of good thermal stability and resistance to heat shock.


  3. The resistance to chemical corrosion and the majority of the metal is not easy to react.


  4.in high temperature in most of the copper base tire body sintering temperature above 800 ℃) intensity increases with temperature rise.


  5. Has the good lubrication and wear resistance.


  6. Easy to processing, mechanical processing performance is good, can be made into complex shapes, high precision molds.
