In [[1931]], he developed such a formulation and collaborated with the German materials firm [[Heraeus]] in Hanau to get access to a vacuum smelter. He developed a new hairspring material that would not change in elasticity due to changes in ambient temperature. The resulting material, an alloy of nickel, iron, and other metals, was particularly valuable in the production of hairsprings and balance wheels.

Reinhard Straumann (November 3, 1892-October 2, 1967) was a Swiss engineer and entrepreneur noted for developing the Nivarox hairspring alloy.
Personal Life
Reinhard Straumann was born on November 3, 1892 in Bretzwil, near Waldenburg in Northwest Switzerland. His father, Reinhard Straumann, was a teacher in Beniwil, but soon moved the family to the town of Waldenburg to teach there. His mother was Anna (née Heinimann) and he had two surviving sisters. The three children attended primary school in Waldenburg but Reinhard Straumann retained his allegiance to his home village of Bretzwil through his life.
From 1908 to 1912, Straumann was a student at the cantonal technical school in Le Locle. He focused on watchmaking technology and precision engineering there, the specialty of that school. After graduating, Straumann worked as a technician in Bienne until 1914. He then trained as an engineer at the Ecole Supérieure d'Aéronautique et de Constructions Mécaniques in Lausanne, graduating with an engineering degree in 1916.
Reinhard Straumann entered military service as a technical operations engineer in the air force following his degree. He was responsible for the evaluation and acceptance of aircraft engines and the design and construction of propellors. He would remain active in the military, earning the rank of lieutenant colonel in the air force.
In 1916, Straumann joined Thommens Uhrenfabrik, Waldenburg's prominent watch factory, as a designer. He quickly rose to become technical director of the factory, which was managed by his cousin, Doctor Hermann Straumann from 1932. He mainly focused on the introduction of wristwatches and, during the war, development of aircraft instruments.
In 1919, Reinhard Straumann married Fanny Heid, and she became his partner and secretary throughout his life. The couple had two children, a son and a daughter, and seven grandchildren.
In his personal time Straumann studied the mechanics of ski flying. In 1926 he published a theoretical model for the construction of modern ski jumps based on the aerodynamics of ski flying. He promoted musical concerts at the school in Waldenburg. He enjoyed watercolor painting as a youth and built a valuable collection of the best-known Swiss painters.
Reinhard Straumann was also active in politics, becoming district administrator. But he was drawn into a controversy after World War II and resigned in protest in 1946.
Reinhard Straumann died on October 2, 1967, just short of 75 years of age.

The new Straumann Department faced an immediate challenge as Albert Ruch died in 1935. Straumann split his department and re-formed it as Nivarox SA in 1937. Reinhard Straumann would remain on the board of the company through his death in 1967. The company would merge with Fabriques d'Assortiments Réunis (FAR) of Le Locle in 1984 and remains one of the most valuable components of the Swatch Group.
Tschudin + Heid and Nivaflex
In 1938, after the death of his father in law, Fritz Heid, Straumann became director of Tschudin + Heid AG. The Waldenburg company specialized in precision lathe work and cutting for watch components as well as hydraulic and pneumatic machine controls. Under Straumann the firm expanded, adding a facility in Bretzwil to process special materials into high-precision parts and another in Reinach to produce fine components for the electronics industry.

It was here that he created and patented a new mainspring material, Nivaflex, in 1948. He established a company, Nivaflex SA, to exploit this material in 1951. Straumann's Waldenburg research laboratory became Institute Dr. Ing. Reinhard Straumann in 1954. The institute focused on areas of interest to Straumann, chiefly ski flying, watch materials, and test equipment. The company would be renamed Straumann AG in 1990 and would focus on development of dental implants.
