Detailed Product Description

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

 

1. Description:

There were two key challenges. The first was to create a design and a manufacturing process that would produce a robust, high-integrity vacuum seal (leak rate 10-8 mbar l/s) across a large component that is 200 mm in diameter. The second was to solve the problem of the difference in thermal co-efficient between the alumina ceramics of the tube and its low-carbon steel flanges. Furthermore, a very tight specification was set for the physical dimensions and cleanliness of the components because of the nature of the project.

 

2. Feature Advantages:

1) High elasticity modulus

2) Chemical inertness

3) High Fracture toughness

4) High temperature resistance

5) Satisfy various technical requests

6) Stiffness texture

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?
