99.98% Pure Nickel Rod & Wire – 1/2 Hard, Ultra-Low Carbon & Sulfur, High Conductivity, Superior Formability

Nickel with highest degree of purity with the following features:

Very low levels of carbon (20 ppm) and sulfur (2 ppm) which tend to segregate at grain boundries resulting in hot shortening

Cleanliness, absence of non-metallic inclusions as Al, Ti or Si oxides

Low electrical resistivity at 20°C

High thermal conductivity at 20°C

Excellent formability

Low softening temperature (350°C)

Low recrystallization temperature (350°C)

Improved oxidation resistance: development of tightly adherent one-layer oxide scale instead of a two-layer costumary one, which tends to flake off due to mismatch in thermal expansion.

Technological properties

Property
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
Heat Treatment	Half Hardened
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.
Surface Finish	Blank/Bare/bright surface
