Nichrome Mesh/Screen

                    NICHROME   WIRE   MESH /SCREEN

Nichrome Wire Mesh/Screen is a name for a Nickel-Chromium alloy wire mesh. Nichrome wire mesh/screen is corrosion resistant and has 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 this productis 105,000 PSI (Pounds per Square Inch), yield strength is around 50,000 PSI and modulus of elasticity is 31 x 106 PSI.

        Nichrome Wire mesh/screen has many advantages, such as deformation ability, thermal stability, mechanical character, shockproof ability in thermal state and anti-oxidization. For heating, resistance Wire mesh must be stable in air when hot. Nichrome Wire mesh/screen forms a protective layer of chromium oxide when it is heated for the first time. Material beneath the layer will not oxidize, preventing the Wire mesh from breaking or burning out. Due to
        Nichrome Wire mesh's relatively high resistivity and resistance to oxidation at high temperatures, it 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.

        Nichrome Wire mesh also has good anti-corrosion and high resistant co-efficiency. Itis commonly used in ceramics as an internal support structure to help some elements of clay sculptures hold their shape while they are still soft.

      Nichrome Wire mesh'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. Nichrome Wire mesh 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. Recommended maximal temperature in the furnace: 1922 / 2012 °F in order to obtain a reasonable life time of the elements.

    1.  Ni80 Cr20: Good deformability and mechanical strength. Its thermal state has good merit, earthquake resistance and anti-oxidized ability. Widely used in chemical industry, machinery, metallurgy, national defense makes the electric stove to heat up and the heat treatment also is the electron, lightly spins material of in the industry electric appliance and electronic, and the resistor part.

The phase diagram for Ni80Cr20 shows no phase transition in the solid state. The two phase region is very narrow (1661–1676 K) and subsequently the measured temperature traces show a flat melting plateau. The solidus–liquidus temperatures of the alloy are lower than the melting temperatures of its pure elements. DTA measurements yielded the transition temperatures of the material, which are slightly lower than the temperatures in the phase diagram of the binary Ni80Cr20 that may be expected due to the amount of 1.5% Si.

      2.    Ni30Cr20 and Ni25Cr20: Nickel-chrome-iron high electric resistance alloy: its workability is well (plasticity good), the weld ability is good, when the corrosion resistance, the thermal state has the good earthquake resistance and the anti- oxidized ability. The application temperature below 1100 ^oC may replace Ni80Cr20 as electric resistance.
