Product Description
Refractory Cylinder Wear resistant Anti-heat Zirconia Ceramic Dowel Rod
Specification:
1.Refractory
2.Long service life
3.High Polished Surface
4. Superior Mechanical Strength
5. Anti-high Corrosion and Wear Resistance
6.Good Insulation Performance
7.High Temperature and Pressure Resistance
8.High Purity Zirconia and Alumina Ceramic Materials . High hardness, long service life, not easy to break and wear resistance
.non-conductive, anti-static, ceramic material itself with the insulation of electricity and magnetism properties
.corrosion resistance, high temperature resistance, can be applied to a specific environment, such as acid alkali resistanceCeramic dowel rod pin is used as guide pin on projection nut welding.It adopt silicon nitride,AL2O3,ZrO2 etc.ceramic material.With good insulation performance,ceramic dowel pin protect electrode when welding workpiece.But due to ceramic is fragile,more and more dowel pin use KCF material.
