Description
Nickel wire is a kind of metal wire with good mechanical strength, corrosion resistance and high heat resistance, suitable for making vacuum components, electronic instrument components, chemical production of strong alkali filter.
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 among metal materials. The surface of nickel wire will form a black protective film in the concentrated alkali, which makes it very resistant to corrosion.Be used at electric illuminant material more, coating film, have surface quality high, machining performance is good, be used at making the job to wait like anode, spacer, electrode bracket, also can be made in bulb guide wire lead, had very important effect in chlor-alkali industry additionally.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.
Advantages of nickel wire :
1.it has weldability, high electrical conductivity and suitable linear expansion coefficient
2.It has better strength and lower resistivity at high temperature
