99.98% Pure Nickel Flat Wire – S-Annealed for Superior Performance

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.

Processing history	Ribbon of high purity nickel is produced by two processing routes: I. slitting of strip: thick coil is rolled down on a modren Bühler reversing to the required thickness. The strip is cut on a high precision slitting line. The minimum band width is 1.0 mm. II. Flat rolling of wire: wire is flat rolled using Bühler flat rolling mill to the thickness between 0.10 to 2.5 mm and width between 1.0 and 12.0 mm.
Surface Finish	Blank/Bare surface
