Type Equal Diameter Silicon Carbide Rods - Low Resistance, Long Lifespan Heating Elements for Industrial Furnaces
![]()
The SiC electric heating elements are mainly made of high quality green silion carbide, it's a kind of tubular and non-metallic high temperature Electric Heating Element produced by processing of msaking semifinished product, high-temperature silicification, re-crystallization. ED Series Equal Diameter Silicon Carbide Rods are advanced replacements for traditional thick-end silicon carbide rods. Featuring uniform diameter structure, these rods deliver 30% lower end resistance than traditional models, significantly reducing thermal stress and prolonging service life. Ideal for high-temperature applications up to 1450°C, they excel in energy efficiency with 15-20% power savings.
SiC electric heating element is widely used in high temperature furnaces and other electric heating equipment of magnetic materials, powder metallurgy, ceramics, glass, metallurgy, machinery and other industries.
