(¹) AV hard-anodized (50µ - Ra=0.4-0.6)
Anodization (hard-anodized or hard-coated) is understood to be the electrolytic oxidation of materials
made of aluminum in order to create a protective layer on the materials made of aluminum.
The layer has a hardness of 400-600 HV (45-65 HRC) and serves as wear and corrosion protection,
is thermally and electrically insulating, and has good tribological properties.
(²) NN chemically nickel-plated
Currentless, chemical nickel-plating is a reduction process in which the objects to be nickel-plated are dipped
in a special electrolyte. Without applying an electrical voltage, a nickel coating deposits on the surface.
Chemical nickel-plating is characterized by an even layer thickness even on holes, recesses, and inside surfaces.
Chemical nickel coatings are not ferromagnetic. The surface hardness is between 400-480 HV (45-55 HRC).
This type of coating is a nickel-phosphorus alloy for which it is possible to control the layer properties
using the phosphorus deposited in the layer. In this case, the alloy has a high phosphorus content (12%).
Nickel is resistant to air, water, diluted acids, and most bases.
Nickel is not resistant to nitric acid, concentrated hydrochloric acid, or ammonia.
(³) TF PTFE-coated
The combination of the described anodization and a PTFE-coating serves as additional protection and
unites the advantages of a hard surface with the chemical and physical advantages of PTFE.
Even more improved corrosion protection, thermal stability, as well as chemical resistance
characterize this surface. Specially suitable for maritime use or offshore applications.
* Stainless steel shaft optional
A high-alloyed stainless steel shaft is recommended for environment subject to strong chemical influences such as
acids and bases, in the pharmaceutical or food industries, as well as in seawater or in high temperature ranges
