SiC Heating Elements
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. Compared with metal electric heating element, this element is characterized by high - applied temperature anti - oxidization, anti - corrosion, long service life, little deformation, easy installation and maintenance. Therefore, it is widely used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet, ceramics, powder metallurgy, glass, metallurgy and machinery etc.
| Resistivity | 1000~4000 Ω·cm |
| Flexural strength | ≥25 MPa |

A seven-zone mesh belt furnace running at 1120 °C can hold ±3 °C across the belt and still ship parts with inconsistent hardness, because the dew point in the delubrication zone drifted after the belt speed was raised. That is the nature of powder metallurgy: the furnace is not a box that gets hot, it is a chemical reactor with a conveyor attached. The short answer: select a powder metallurgy furnace by the process window it must hold — delubrication profile, atmosphere quality, sintering tempe...
