Product Description

Product Description

Precision ceramic processing parts

Alumina ceramic is kind of structural ceramics, with insulation resistance, voltage resistance, high strength, good thermal conductivity, dielectric loss, stable electrical performance characteristics. Used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, devices porcelain, spark plugs and other products. We can make the part by hot injection pressing, dry pressing, 200T isostatic pressing and extrusion productive technology etc.

 

Zirconia ceramics is a kind of ceramic material based on zirconia.In terms of structural ceramics, zirconia is different from traditional ceramics. Zirconia has very high strength, wear resistance and flexibility, which far exceeds most other technical ceramics. Zirconia is a very strong industrial ceramic with excellent properties in hardness, fracture toughness and corrosion resistance. Compared with metals,in daily use special ceramics have the characteristics of non-rusting, non-magnetic, wear resistance and insulation, so zirconia ceramics have high toughness, high bending strength and high wear resistance, as well as excellent thermal insulation and Coefficient of thermal expansion similar to steel, so it is widely used in the field of structural ceramics.

95% 99% 99.7% alumina ceramic substrate 

Application:
They are used in thick film circuits, ceramic metallization, ozone generators, audio, LED lighting, electronic insulation devices,solar new energy and other industries.

Features:
It has the characteristics of low dielectric loss, stable electrical performance, smooth surface, consistent thickness, good
flatness, and overall dimensions,ect.

Size:
The thickness can be produced from 0.25mm -----15 mm, and the ceramic substrate can be punched and lineated.

We can customize to your requirements. Below sizes are some examples.
