Description:
-
The silicon carbide (SIC) heating element is a kind of non-metal high temperature electric heating element.
-
It is made of selected super quality green silicon carbide as main material, which is made into blank, solid under high temperature and re-crystallized.
-
It is widely used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet, ceramic, powder metallurgy, glass, metallurgy and machinery etc.
Features and Specification:
| Specific gravity | 2.6-2.8g/cm³ |
| Bend strength | ＞300kg |
| Hardenss | ＞9MOH'S |
| Tensile strength | ＞150kg/cm³ |
Resistance:
We test the resistance when the heating element was heated and it's surface temperature up to 1050℃，because the resistance of SIC heating elements will be stable at 1050℃.
