We add value to your parts
Normally sulfamate nickel finds its usage in technical applications for example in the electronic industry and machinery equipment. One of the major advantages of sulfamate nickel layers is the low level of internal stress.
For deposition of a thick, stress-free, technical layer sulfamate nickel is highly recommended. The layer is ductile
and gives a good resistance against wear and corrosion.
Sulfamate nickel can be perfectly machined. For decorative applications sulfamate nickel is, for example used as a
base layer for a mirror bright chromium plated part.
The nickel layer is responsible for the shiny appearance
and corrosion resistance, the chromium layer provides
the nickel layer for oxidation and maintains the shiny appearance. Theoretically there is no limitation on the layer
thickness. Of course, the economic aspects have great influence on the finally chosen layer thickness.
Max. layer thickness
Up to approx. 2 mm
Corrosion resistance
Pore free layers with a thickness of 60 – 70 µm will react
in corrosion tests as Nickel
material. This means a good
resistance against oxidizing agents and a moderate
resistance against reducing
agents.
