Nichrome Heating Coil
Nichrome Heating Coil is a name for a Nickel-Chromium Heating Coil. It is corrosion resistant and has high melting point of about 1400 °C (2552 °F). The heating coil has relatively high resistivity and very good resistance to oxidation at high temperatures.
Nichrome Heating Coils have many advantages, such as deformation ability, thermal stability, mechanical character, shockproof ability in thermal state and anti-oxidization. For heating, resistance Heating Coil must be stable in air when hot. Nichrome Heating Coil forms a protective layer of chromium oxide when it is heated for the first time. Material beneath the layer will not oxidize, preventing the Heating Coil from breaking or burning out.
Due to Nichrome Heating Coil's relatively high resistivity and resistance to oxidation at high temperatures, Nichrome Heating Coil is widely used in heating elements, electric furnace heating and heat-treating processes in the chemical, mechanical, metallurgical and defense industries, such as in hair dryers, electric ovens, toasters, vacuum coating, inner components of vacuum valves, etching resistor, brake resistor, tube heater, sealer and boiler.

Nichrome Heating Coil also has good anti-corrosion and high resistant co-efficiency. Nichrome Heating Coil is commonly used in ceramics as an internal support structure to help some elements of clay sculptures hold their shape while they are still soft.
Heating Coils are specified in resistance, volt-amps (watts), outside diameter (OD), wire diameter and pitch or coils per unit length. It can be manufactured according to the customer's requirements.
Applications of Nichrome Heating Coil: Heating Coils are found in consumer and industrial applications. Large diameter Heating Coils are used within plastic injection molding, blow molding machines, autoclaves, industrial paint booths, food processing equipment, and environmental chambers. Consumer applications include hair dryers, residential space heaters, electric ovens, and electric central heating systems.
