    ED Type Equal Diameter Silicon Carbide Rods Low Resistance Long Lifespan Heating Elements For Industrial Furnaces

    Type Equal Diameter Silicon Carbide Rods - Low Resistance, Long Lifespan Heating Elements for Industrial Furnaces

    Description:


    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.


    Typical application:


    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.


    The physical properties of silicon carbide Rodes:
