FerNiCo I has the same linear coefficient of expansion as certain types of borosilicate ("hard" glass), (c6.5 × 10 −6 K −1, thus serving as an ideal material for the lead-out wires or other seal structures in light bulbs and thermionic valves. Dumet is also used for this purpose, but for passing through softer soda-lime and lead-alkali ...

Dumet-wire is a copper clad wire (25% of copper by weight) with a core of nickel-iron alloy 42 (42% of nickel by weight). [10] The core having low CTE makes it possible to produce a wire with a radial CTE lower than a linear CTE of the glass, so that the glass-to-metal interface is under a low compression stress.
Very importantly, constantan can be processed for self-temperature compensation to match a wide range of test material coefficients of thermal expansion.A-alloy is supplied in self-temperature-compensation (S-T-C) numbers 00, 03, 05, 06, 09, 13, 15, 18, 30, 40, and 50, for use on test materials with corresponding thermal expansion coefficients, expressed in parts per million by length (or μm ...
The Notz Metal (officially Notz Metal, Inc.) is a Swiss integrated steel and wire manufacturing company based in Biel/Bienne (BE), Switzerland.Founded in 1898, the company is still privately held and managed by the third generation of the Notz family.
trans,trans,trans-(1,5,9 Cyclododecatriene)nickel(0) a organonickel compound with the formula NiC 12 H 18, better known as t-Ni(cdt). It is a 16-electron coordination complex featuring trigonal planar nickel (0) bound to the three alkene groups in the cyclododecatriene ligand . [ 1 ]
A number of units were used to measure length. One pied (1 fuss) was equal to 0.30 m, according to the fixed value defined during the transition to the metric system. [1] [4] Some other units and their fixed values are given below: 1 ligne = 1/144 pied 1 linie = 1/144 pied 1 pouce = 1/12 pied 1 zoll = 1/12 pied 1 aune = 2 pied (or 4 pied [3])
