ED-Type Silicon Carbide (SiC) Heating Elements
High-performance non-metallic electric heating components rated for 1450°C operation in industrial stoves and furnaces.
Product Overview
ED-Type (Equal Diameter) Silicon Carbide Heating Elements are engineered for extreme temperature environments. Manufactured from high-purity green silicon carbide and sintered at 2400°C, they deliver exceptional thermal stability and mechanical strength. Designed for continuous operation from 600°C to 1450°C, these elements are perfect for electric stoves, kilns, and industrial heating systems across glass manufacturing, chemical processing, and electronic materials synthesis.
Key Features
- High-temperature resistance up to 1450°C
- Low thermal expansion for minimal deformation
- Excellent chemical and oxidation resistance
- Long service life with easy installation & maintenance
- Custom diameters, lengths, and shapes available
