Detailed Product Description

High-Density Alumina Ceramic Components for Automotive Applications

 

1. Description:

The ceramic/metal brazed sub-assembly is then welded to the flanges with a stainless steel interface and machined to the final dimensions. The order from ISIS was for 13 components supplied by the end of 2006. As is usually the case with this sort of project, no extra time or budget was available to produce a prototype to refine the process. Therefore, the experience and expertise of the specialist team were critical to getting it right the first time. Working together, the team solved problems as they arose, and all the components were delivered. Construction of TS-2 began in July 2003, and first neutron production is planned for the autumn of 2007.

 

2. Feature Advantages:

1) High compressive strength.

2) High stability

3) High welding sealing performance

4) Good insulation performance

5) Satisfy various technical requests

6) 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?
