CNC Machined Machinery Ceramic Parts
Engineering Ceramic Engineering alumina ceramic insulators are made from a combination of alumina and other ceramic materials. Alumina is a highly durable, heat-resistant material that is used in a variety of industrial applications. It is an ideal material for use in insulators because it is strong, lightweight, and non-conductive. Engineering ceramics are made from a variety of materials, including alumina, zirconia, and silicon nitride. These materials are used in a variety of applications, including electrical, thermal, and optical applications. Engineering alumina ceramic insulators are designed to provide insulation from heat, electricity, and radiation.
Advantage:
1. Good electrical insulation
2. Moderate thermal conductivity
3. High corrosion and wear resistance
4. High mechanical strength
5. High compressive strength
6. High hardness
Except for the ZTA resistance lining ceramics , we manufacturer many other advanced ceramic parts, like ceramic substrates, ceramic plunger ,ceramic disc,ceramic tubes,ceramic rod,ceramic sealing piston ,ceramic grinders, ceramic guides and so on.
