High Temperature heat Resistance Al2o3 Ceramic Insulator is widely used for nuclear, microwave high vacuum insulation, high
precision magnetism-free skeleton for aeronautic and astronautic
electrical devices, ultra-high voltage insulation for electric
motors and structural parts at strong erosion
environments. In terms of machinability, it can take place of
aluminum oxide and boron nitride ceramics that are difficult to
machine.
Alumina Ceramic can be made by different purities like 95%, 96%, 99%, 99.5%, 99.7% etc, their properties will have little difference accordingly.
●Good strength and stiffness
●Good hardness and wear resistance
●Good corrosion resistance
●High thermal conductivity
●High temperature resistance
●Electrical insulation
●Low dielectric constant

The high temperature ceramic have best heat properties for ceramic component parts.
Ceramic materials for ceramic components generally have high melting point (mostly above 2000℃) and excellent chemical stability and best insulation at high temperature.Ceramic thermal conductivity for ceramic parts is lower than metal materials, and a good thermal insulation material.At the same time, the linear expansion coefficient of ceramics is lower than that of metals. When the temperature changes, ceramics component parts have good dimensional stability.
Ceramic components have a best ceramic propertied performace with high hardness, high strength, high temperature resistance, high and low temperature impact performance, low coefficient of thermal expansion, low temperature creep, good oxidation resistance, good thermal corrosion performance, low friction coefficient and many other excellent performance.
