Customer Reviews
This is the first time for our cooperation. They are indeed what we want. We look forward to working with you again in future.

—— Fred (USA)

Your ceramic tube is really good for our application, we will buy more in future.

—— Jessica Ferrara (Italy)

You are the best, your ceramic parts are perfect

—— Dalibor(Czech)

Our client satisfied with the Cordierite kiln shelf and sagger . But It would be better if the delivery time be shorter in our next order.

—— Van Nguyen (Viet Nam)

I hope you are fine and business is well. We recieved the perfect goods from you, your are the best.

1.Product description of alumina ceramic disc 

Ceramic disc  are used in many electronic applications where a thin insulating layer of thermally stable material is required to conduct heat away from electronic components whilst electrically insulating them, and material is 96% alumina, zirconia, silicon nitride and aluminum nitride, All our substrates are produced by laser cutting and surface grinding.

Properties with excellent insulation, high mechanical strength, high thermal conductivity, low expansion coefficient, small dielectric constant, high-temperature resistance, excellent erosion and wear resistance, good quality in chemical shock heat and cold.

 

All alumina ceramic disc could be customized according to your data requirements and drawings.

 

2. Features and advantage of alumina ceramic disc 

1.Great mechanical strength

2.Low thermal conductivity

3.High heat resistance

4.High softening temperature

5.Small thermal expansion coefficient

6.Good cold-resistance heat-resistance

7.Resistance to acid and alkali corrosion

8.Long service life
