1.High strength & good compactness

2.Low thermal espansion coefficient

3.Excellent thermal shock resistance

4.No wetting by molten aluminium and other ono-ferrous molten metal

5.Good corrosion resistance

Application 

Used to protect the temperature-measuring components, make the components isolate from the outside substance, reduce and prevent the corrosion, oxidation and mechanical damage to the components during measuring.
