CoCr and Alloys

Cobalt-Chrome (Co-Cr) is a metal alloy of Cobalt (59 to 68%), Chromium (27 to 30%), Molybdenum (5 to 7%), and other important elements (less than 4%). Following ASTM F75, this metal “is a non-magnetic CoCrMo alloy exhibiting high strength, corrosion resistance, and excellent wear resistance”.
The CoCrMo alloys are especially used where high stiffness or a highly polished and extremely wear-resistant material is required, as well as in situations where material quality is imperative as parts are heavily loaded and subject to fatigue.
CoCrMo alloys are widely used for aero- and land-based gas turbines (fuel nozzles and blades) and for medical applications, like prosthetic implant devices, knee implants, hip joints, orthopedic implants and dental prosthetics. In recent time, CoCr alloys have been intensively explored for cordial purposes.
Electro-polishing of CoCr parts might contribute to all those heavy industrial applications. However, during the period when they were mostly developed, design engineers have yet not had this surface treatment process in their stock of instrumentation. In contrast, for resent applications, like cordial devices, research and design engineers turn to Electropolishing as a powerful instrument to bring CoCr surface into line with the requirements.
Finish Line has developed few modifications of CoCr Electro-polishing Process, which were successfully implemented at various stages of R&D projects, conducted in frames of start-up companies see example.

Anode Treatment

Anode treatment beneficiates metal surface through metal dissolving and oxidation. In case no coating is allowed, Anode Treatment is a way to enhance your parts’ surface qualities. more >>


Passivation is a classic anode treatment to improve corrosion resistance of metals, comparing to not treated parts, through completing natural formation of metal oxides surface layer. more >>

Bright Passivation

Bright Passivation improves corrosion resistance of metals, comparing to not treated parts, removes spots from previous processing and provides the parts with brighter appearance. more >>


Etching is an old craft which technically comprises a vigorous anode treatment process, widely exploited in industry. Etching metal surface as a whole makes it uniformly rough and porous more >>

Color Anodizing

Color Anodizing is a unique Titanium only applied process granting to metal surface a wide spectrum of controllable vivid interference colors, which are stable, uniform and repeatable more >>

Surface preparation

Surface preparation ensures the after Anode Treatment surface features as aimed. It includes both quality improving (like de-burring) and surface beneficiation (like surface roughening) more >>

Surface cleaning

Surface Cleaning is an essential completing operation after any Anode Treatment intended washing the surface from leftovers of previous treatment, using purified water at the end step more >>
