High Precision Durable Zirconia Ceramic Rod Shaft For Electrical
1. ZrO2 ceramic rod shaft made of yittria stablized zirconium oxide ceramics. This kind of application of zirconia ceramic parts mainly take use of the exceptional wear resistace with self-lubrition, low thermal expansion cofficient with good thermal shock and high temperature resistace, characteristics.
2. We offer diversity of different grade material of zirconia, such as partial stablized zirconia, fully stablized zirconia.
3.The largest outer diameter can be 30mm.
4.Special type, different size can be custom made per customers' drawing through moulding directly, laser cutting or CNC machining processes, fine ground.
6.High quality surface, with outstanding roughness and without any cracks after many times cycles.
7.They are famous on high hardness, good insulation, low friction, excellent wear resistance, chemical resistant , resistant high temperature , thermal shock resistant and so on.
Application:
Widely used as structural ceramics, wear parts, cutting tools, thread and wire guides, fiber optical ceramic components, oxygen sensors, thermal barrier coatings, high precision ball valve, solid oxide fuel cell components and son on.
