Nivarox is the common name for the alloy from which the company manufactures its products. Nivarox is an abbreviation of the German Nicht Variable Oxydfest ( unchanging, non-oxidizing ).
There are several types of alloy, depending on the destination - with a high content of cobalt (42-48%), nickel (15-25%) and chromium (16-22%). In addition, there is a small content of titanium and beryllium . Hair springs made from these alloys are wear resistant, almost completely non-magnetic, stainless and have a low coefficient of thermal expansion .
Nivarox alloy is mainly used in the watch industry, but in addition it is used in the manufacture of medical equipment and surgical instruments.
