                                               Nickel Chromium Resistance Wire

Nickel Chromium Resistance Wire
is corrosion resistant, and has a high melting point of about 1400 °C (2552 °F). It has relatively high resistivity and very good resistance to oxidation at high temperatures. The ultimate tensile strength of Nickel Chromium Resistance Wire is 105,000 PSI (Pounds per Square Inch), yield strength is around 50,000 PSI, and modulus of elasticity is 31 x 106 PSI.

Nickel Chromium Resistance Wire Applications:

Nickel Chromium Resistance Wires
have many advantages, such as deformation ability, thermal stability, mechanical character, shockproof ability in thermal state and anti-oxidization. For heating, Resistance Wire must be stable in air when hot. It forms a protective layer of chromium oxide. Due to its relatively high resistivity and resistance to oxidation at high temperatures.

Nickel Chromium Resistance Wire 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, boiler and even electronic cigarettes.

Nickel Chromium Resistance Wire is wound in coils to a certain electrical resistance, and current passed through to produce heat. They are also used as material of industrial equipment and electrical resistant elements in the electronics and light textile industries.

Nickel Chromium Resistance Wire
is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath the Resistance Wire will not oxidize, preventing the Resistance Wire from breaking or burning out. so it is good for anti-corrosion and high resistant co-efficiency.

Nickel Chromium Resistance Wire is applicable for heat treatment, air-carbon furnace, chemical industry, machinery, metallurgy. It 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.Nickel Chromium Resistance Wire's metallurgical structure confers them a very good plasticity when cold. There is a growth of the grain under heat during utilization of the element without inducing embrittlement of it when cold.

Nickel Chromium Resistance Wires are used for the manufacture of electric resistances for appliances (insulated elements type tubular resistances or for example opened elements on micanit plate) or for application of industrial furnaces. In addition of a relatively high specific resistance, Ni-Cr alloys join all the necessary properties for good performances in use of furnaces: Resistance to oxidation (they are not sensitive to aggressions of humid air). Low embrittlement at high temperature Good plasticity – Easier to give them a shape compared with Fe Cr Al (lower mechanical characteristics allow indeed a good control of elasticity of the product during shaping (coiling, folding, drawing). Good resistance to creeping (more important than ferritic alloys) which is important during conception of a resistance presenting big heights of waves. Maximal temperature recommended in the furnace: 1922 / 2012 °F in order to obtain a reasonable life time of the elements.
