U SiC Heater

U type SiC heating elements

The U type  silicon carbide heating elements is manufactured by taking two carefully-matched SiC rods and uniting them with a silicon carbide bridge.These elements provide for wiring both terminals from one side of the furnace. Ideal for drop-through designs, radiant tube systems or where one element will not span the heating chamber. For maximum performance up to 1600 deg C.

This type is “U”-shaped, consisting of a combination of one each of the hot zone rod and cold zone rod respectively. It is a single-phase heating element with both cold ends in one direction, facilitating increased furnace design flexibility, because connection terminals can be centered on one side. In addition, a furnace with an energy saving structure can be built because the number of heating element holes on the furnace can be reduced compared with the U types.

Silicon carbide SiC heating elements, composed of high-purity, recrystallized silicon carbide, have earned the reputation as the world’s leading heating elements. These elements are widely used as high-temperature heat sources for electric furnaces and for the firing of ceramic capacitors, ferrites and other electronic components,


  1. Withstands temperatures as high as 1600°C
  2. Generates high heat output per unit surface area, approximately 5-10 times the output of Nichrome wire
  3. High strength and excellent shock resistance
  4. Chemically stable
  5. Heat source is free of noise and air pollution
  6. Various coating products are available for protection against water vapor and harmful gas atmosphere
  7. Easy to handle
  8. Higher density resulting in longer life
