Nivarox (Nicht Variable Oxydfest - Not Variable Resistant to Oxidation) is a metallic alloy used mainly in the watch industry. This alloy, composed of iron, 40 % nickel, chromium, titanium and beryllium has properties which are useful in building the balances. Hairsprings made of this alloy will not wear out; they are almost non-magnetic, anti-rust and they have a low coefficient of thermal expansion.
Nivarox stabilizes the movement of the watch and makes it more resistant to temperature variations. This alloy made obsolete the expensive and sophisticated compensation balance. Nivarox escape wheels are used on different levels of production by most watchmakers worldwide.
Nivarox is produced by a single Swiss manufacturer - Nivarox-FAR.
