Product Introduction

Universal silicon carbide rods offer outstanding heating capabilities ranging from 800 to 1450 degrees Celsius.

It's a reliable choice because it doesn't deform or bend during high-temperature operations and heats uniformly.

Product specifications

We can provide standard straight products and customized designs, meeting various requirements for industrial electric heating.

Our factory makes diameters ranging from 10 millimeters to 55 millimeters, while the longest length can be up to 4 meters.


1. Straight type

2. Five segment type

3. U-shaped 1

4. U-shaped 2

5. Gun type

6. H-type

1. High operating temperature:

The internal silicon carbide crystal structure is firm and uniform, heats up rapidly, and the highest surface temperature can reach 1450 degrees Celsius, which can exhibit excellent performance in various high-temperature processes.

2. Excellent oxidation resistance and corrosion resistance:

The natural oxidation resistance and corrosion resistance of silicon carbide materials, combined with ultra-high temperature sintering technology, make silicon carbide rods have strong oxidation resistance and corrosion resistance even in the hot state. This ensures the stability and reliability of long-term use.

3. Accurate temperature control:

Silicon carbon rod electric heating elements have strong thermal radiation ability, rapid heating, and precise temperature control. This gives it significant advantages in processes that require fine temperature regulation.

4. Not easily deformed at high temperatures:

Compared to metal electric heating elements and molybdenum disilicide electric heating elements, silicon carbon rod (SiC) heating elements have a smaller coefficient of thermal expansion, are not easily deformed at high temperatures, can be installed vertically or horizontally, and are suitable for various furnace types.

5. Easy installation and maintenance:

The design of silicon carbide rod products is flexible and can be processed into various shapes and specifications, such as straight, U-shaped, H-shaped, etc. Meanwhile, its installation method is simple and can be used in parallel, series, or mixed, greatly simplifying the installation and maintenance process.
