Cost-effective mini coil heater small tubular heater heating elementwe comprise a fine coil of resistance heating alloy wire, usually Nichrome (NiCr) that is connected at each end to a terminal pin and is electrically insulated from a metallic tube, of stainless steel alloys, such as Incoloy, or Copper, by in a ceramic insulating material, fused magnesium oxide powder. The tube ends are frequently equipped with beads of insulating material such as ceramic or silicone rubber, or a combination of both to prevent the penetration of moisture in to the element. These can be a straight rod (as in toaster ovens) or bent to a shape to span an area to be heated (such as in electric stoves, ovens, and coffee makers).
