One of the most important company in the entire world of Swiss horological industry. Now owned by the Swatch Group, Nivarox makes the vast majority of the parts that make mechanical watch movements function.
Nivarox is also the trade name of the metallic alloy from which its products are manufactured. Its notable property is that its coefficient of elasticity is remarkably constant with temperature. As a trade name, Nivarox is a German acronym for “Nicht variabel oxydfest” (G.) or “Non-Variable Non-Oxidizing”.
The Nivarox alloy is a nickel iron alloy (Fe 54 %, Ni 38 %, Cr 8 %, Ti 1 %, Si 0.2 %, Mn 0.8 %, Be 0.9 %, C <0.1 %) used mainly in the watch industry for hairsprings for balance wheels. When used for critical watch components, the alloy reduces errors due to temperature variation. Hairsprings made of this alloy have a spring constant which does not vary with temperature, allowing the watch’s balance wheel, its timekeeping element, to keep better time.
