pure nickel wire
Pure nickel wire has good mechanical strength, corrosion resistance and high heat resistance. It is suitable for making electric vacuum devices, electronic instrument components, and as a corrosion-resistant material in the chemical industry.
The mechanical properties of nickel are close to carbon steel, and its alkali corrosion resistance is second only to silver among metal materials. Nickel will form a black protective film on the surface in concentrated alkali, making it very corrosion resistant. It is mostly used for electric light source materials and coating, with high surface quality and good processing performance. It is used for making work such as anodes, separators, electrode brackets, etc. It can also be used as a guide wire in bulbs. effect. Electrode materials have alloys of various compositions due to different conditions of use. Moreover, the electrode materials are required to have low resistivity to avoid overheating of the electrode, high temperature strength to reduce material wear, and viscous melting and volatilization under the action of the arc to improve the service life and other properties.
Advantages of nickel wire:
●With solderability, high electrical conductivity, suitable coefficient of linear expansion
●Good strength at high temperature, low resistivity
Electrovacuum nickel N4 and N6 have good processing performance, excellent mechanical properties, physical properties, high melting point, good corrosion resistance, and sufficient thermal strength. They are mainly used in electric vacuum devices, electronic instrument components, and chemical industry. Important structural materials in electronic devices. It can also be used in the weaving industry to make nets for various purposes.
