Product Description

Alumina ceramic components / relay ceramic assemblies / ceramic - metal brazed contactor

 

1. Description:

Metallization for ceramics has two main components. It consists of glass (manganese disilicide) and metal particles (molybdenum (Mo) or tungsten (W)). Where the glass connects to the ceramic and the metal particles connect to the metal component via the solder.

 

2. Feature Advantages:

1) A variety of specifications is available

2) Satisfy various technical requests

3) Lower medium spoilage

4) Stiffness texture

5) Widely apply for automotive ceramic sensor , ceramic heater ,electric heating

13Guiding questions for material selection:

In order to select the appropriate material for your application, there are several questions that you should consider.

1) Are the mechanical properties important?

2) Will the part be exposed to wear/friction/impacts?

3) How many pieces are you looking to have made in your first batch?

4) What type of atmosphere will the part be operating in; inert or oxidizing?

5) What is the maximum operating temperature of the component?

6) Will the component experience any thermal shock?

7) Is electrical insulation important?

8) Is thermal conductivity important?

9) How important are tolerances and surface finish?
