Pure nickel resistance wire

Pure nickel wire has the characteristics of good strength at high temperature, good plasticity, poor thermal conductivity and high resistivity.

Application areas

Wire: Sputter Targets, evaporation pellets, regulator coil in glow plugs of diesel engines; litz wire for current conduction under elevated temperatures and in aggressive environments, Pre material for thin wire manfacturing, Ni wire mesh, Thermal Spraying, Coating layer for corrosion protection from alkalis; salt spray; molten salt and reduciing chemicals; coating layer for high temperature resistance; corrosion protection at high temperatures; coating layer for membrane walls of power plants

Processing history

For producing wire, the 6 mm hot rolled thick plates are cut into 6 mm wide sticks. The sticks are frontally welded. Afterwards the raw wire can be treated in the same way as hot rolled wire produced by melt metallurgy. accordingly, the wire is drawn to the desired dimensions through cold drawing and intermediate annealing.
