Afterwards, in 1920, when he received the Nobel Prize in Physics, he developed another alloy-"'Elinvar " '.
12.
A recently patented variant by Innalabs uses a cylindrical design resonator made from Elinvar-type alloy with piezoceramic elements for excitation and pickoff at its bottom.
13.
Springs made of Elinvar, and other low temperature coefficient alloys such as Nivarox that followed, were not affected by temperature, so they made the temperature-compensated balance wheel obsolete.
14.
Elinvar has a near-zero thermal coefficient of the modulus of elasticity, making it useful in constructing instruments with springs that need to be unaffected by varying temperature, such as the marine chronometer.
15.
Nickel is used in many specific and recognizable industrial and consumer products, including stainless steel, alnico magnets, coinage, rechargeable batteries, electric guitar strings, microphone capsules, plating on plumbing fixtures, and special alloys such as permalloy, elinvar, and invar.
16.
The Nivarox alloy is a nickel iron alloy used mainly in the watch industry for hairsprings for balance wheels, but also in other micro-machine industries and in certain medical equipment and surgical instruments, in the same category as Elinvar, Ni-Span, Vibralloy and other similar.
17.
Charles �douard Guillaume won a Nobel prize for the 1896 invention of Invar, a nickel steel alloy with very low thermal expansion, and Elinvar ( " "'El "'asticit?"'invar "'iable " ) an alloy whose elasticity is unchanged over a wide temperature range, for balance springs.
