Usage
The nickel-based electric vacuum material produced by TANKII has below advantages: excellent electrical conductivity, weldability (welding, brazing), can be electroplated, and a suitable linear expansion coefficient of the alloy inclusions, volatile elements and gases content is low. Processing performance, surface quality, corrosion resistance, and can be used to make the anode, spacers, electrode holder, etc., but also can lead filament bulbs, fuses.
Features
The company electrode material (conductive material) having a low resistivity, high temperature strength, the smaller the arc melting under the action of evaporation and so on.
The addition of Mn to pure Nickel brings much improved resistance to Sulphur attack at elevated temperatures and improves strength and hardness, without appreciable reduction of ductility.
Nickel 212 is used as a support wire in incandescent lamps and for electrical resistor terminations.
