 |
Genearl characteristics:
It has many advantages,for example,good self-lubricating property,corrosion resistant property,lower coefficient of friction,higher coefficient of heat conductivity,lower coefficient of thermal expansion,etc. |
 |
|
 |
It is in high corrosion resistant and wearing resistant,has a higher mechanical strength,a good resistance to elevated tempetature,and a good selflubricating property.This is the best materical matching to graphite.

|
|
Tungsten carbide-it is in high corrosion resistant,has a high bend strength,a lower coefficient of thermal expansion and a higher coefficient of heat conductivity.It is the seal ring material that has the highest coefficient of thermal impact. |
 |
|
|
It is in excellently corrosion resistant and wearing resistant,and has a lower coefficient of thermal expansion.It is widely used in medium and lower load mechanical seals. But its thermal impact property is not good. | | | |
