Refractory zirconia ceramic flush pin plug gauge / needle gauge / measuring pin gauge with corrosion and heat resistance
Product Description
Advantages of Zirconia ceramic pin gauge:
1. Refractory.
2. Self Lubricating.
3. Long Service Life.
4. Good Polished Surface.
5. Environmental and Healthy.
6. Superior Mechanical Strength.
7. High Corrosion and Wear Resistance.
8. Good Insulation Performance Precision.
9. High Temperature and Pressure Resistance.
10. High Purity Zirconia and Alumina Ceramic Material.
The ceramic guide pins are made of grey zirconia ceramic material.We also offer other ceramic material,such as white ceramic,blue ceramic,black ceramic.Grey ceramic guide pin is a high temperature heat treatment of white ceramic through sintering furnace.This way add ceramic guide pin’s strength.So our grey ceramic guide pins are more hard and strength,high wear resistance and longer life than other ceramic pins.
