Millions of people suffer from allergies caused by nickel release.

Our company is particularly sensitive to this serious issue and works in compliance with the provisions in force. In the years, it has analyzed and developed new nickel free finishes that are today our point of strength.

Among the most important nickel free finishes there are:

There are hundreds of colours that the company has, in the years, developed and tested and that are now a part of the nickel free finishes.

Gesm SpA´s nickel free bath is a process that deposits a white bronze alloy. It can be used as a finish or as a substratum for further deposits, even precious ones. It is an excellent substitute for nickel.

The process is characterized by the following features:

Gesm SpA´s gunbarrel-coloured free bath is a process that produces a darker deposit compared to the traditional "gun barrel" finishes.

That is because nearly everybody on the market uses, for this type of finish, a tin-cobalt alloy, while ours, considering its chemical composition, produces electroplatings that, on the customer's specific request, can have different colour shades, ranging from the lightest to the darkest, such as a very dark blue.

Gesm SpA's blackening free bath is a process that, depositing a cobalt, zinc and tin alloy, produces finishes with shades ranging from blue-black to dark brown.

This kind of bath is mostly used with parts that will subsequently undergo antique finish processes.
