Nickel mechanical properties close to carbon steel, the alkali resistance performance of corrosion in metal material is second only to silver, nickel wire in concentrated alkaline surface generates a layer of protective film of black, making it very corrosion resistant.

With high surface quality and processing performance is good, used to make such as anode, spacers, electrode holder, etc., it's also used in the light bulbs as thread lead, in addition in the chlor-alkali industry has played a very important role. 

Electrical grade materials have a variety of components due to the use of different conditions of alloy. Moreover, the electrode materials are required to have a low resistivity so as not to cause overheating of the electrode, a high temperature strength to reduce material wear, and a more viscous melting volatilization under the action of arc to improve the service life and other properties.

Characteristics:

1, with weldability, high electrical conductivity, suitable linear expansion coefficient

2. Good strength and low resistivity at high temperature

3, high melting point, corrosion resistance, good mechanical performance, in hot and cold state have a better pressure processing, easy to degas, suitable for radio, electric light source, mechanical manufacturing, chemical industry, is an important structural material in vacuum electronic devices.

Pure nickel wire can be divided into N4 and N6 according to the material.
