Dianoir® G4 is skin friendly

Many fashion accessories (earrings, rings, bracelets, etc.) are made with materials containing nickel.

The standard legislation EN 1811: 2011 + A1: 2015 (see below) has set nickel release limits for objects in contact with the skin.

Objects inserted in perforated parts of the human body

Objects intended to come into direct and prolonged contact with the skin

Argor-Aljba has developed the Dianoir® G4 DLC coating which, in addition to embellishing the objects coated with its deep black, is able to reduce the release of nickel ions by 80%, helping to make the objects themselves hypoallergenic.

With dianoir® G4 the world of luxury and fashion comes into a new aesthetic and technical dimension.

Low friction coating

It is estimated that 20% of all energy produced is used to overcome friction, mainly in industry and transport. The interaction between two surfaces generates friction which causes loss of energy and can also damage the surface itself. Lubricating oils help to decrease the friction coefficient but represent an environmental risk in their own right. A low friction PVD coating, especially a diamond-like carbon coating (DLC), is an excellent solution.
