Top Performance in Machining – Without Sticking Together
Our SILVER aluminium titanium chrome nitride coat is one of those hard coatings especially well suited for very special areas of application: It is mostly used in the machining of materials that tend to stick together. Due to its high levels of hardness and excellent oxidation resistance, SILVER is particularly well suited for all those machining tasks that bring other coatings to the limits of their thermal stress capacity.
One Very Special Hard Coating …
Thanks to SILVER’s smooth CrN surface, the tendency to stick together is significantly and effectively reduced when using this hard coating. With its silver colour, the coat is used for the machining of abrasive materials that tend to stick together, such as stainless steel, grey cast iron or silicium-rich aluminium alloys.
Machining of Aluminium, Copper and Non-Ferrous Metals
Fully following this design, SILVER hard coatings are mainly used in the machining of aluminium and aluminium alloys, copper and other non-ferrous metals. But these hard coatings are also popular in the area of aluminium and magnesium injection moulding as well as in the forming of aluminium sheets.
