Pure nickel (N4 / N6)

    Pure nickel (electric vacuum material) N4 / N6

The mechanical property of nickel is close to that of carbon steel, and its resistance to alkaline corrosion is second only to that of silver in metal material, and the surface of nickel will produce a black protective film on the surface of concentrated alkali. My company production of nickel based electric vacuum material (N4, N5, N6, N8, UNS N02200, UNS N02201), a strip, wire, bar, with high surface quality, good processing performance, for a variety of molded parts made of high temperature work. The utility model can also be used as a guide wire lead wire in a bulb, and can also be used as a positive and negative pole connection in a battery. Also played a very important role in chlor alkali industry.

Electrical grade materials with different conditions of use, and a variety of components of the alloy. And the electrode materials are required to have low resistivity to avoid electricity

Extremely hot, high temperature strength to reduce the wear and tear of material, under the arc of the melting of the more viscous evaporation to improve the service life and other properties.

The following characteristics:

Having weldability, high conductivity, suitable linear expansion coefficient.

The high temperature strength, low resistivity.

The following main technical indicators
