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 ...
1 setier = 25 pot 1 muid = 4 setiers 1 pot = 1.5 L (1.585 quarts). [3] Pot was the bulk of 3 livres weight of pure water at the temperature of 4 °C. Pot was equal to 1/18 pied 3 and was subdivided into 1/2, 1/4 and 1/8. [3]

Three-phase plugs have a dimension of 35.4 (± 0.7) × 30 (± 0.7) mm. Pin length of the connector The pins are 19 mm (± 0.5 mm) long on all types. The length of the insulation on the connector pins is 8 mm (± 0.25 mm). Diameter of the pins and the openings The pins of the 10 A connector are 4 mm (± 0.06 mm) in diameter.
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 ]
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 ...
Chemically, it bonds to glass via the intermediate oxide layer of nickel(II) oxide and cobalt(II) oxide. The proportion of iron oxide is low due to its reduction with cobalt. The bond strength is highly dependent on the oxide layer thickness and character.[4][6] The presence of cobalt makes the oxide layer easier to melt and dissolve in the ...
Strip of permalloy. Permalloy is a nickel–iron magnetic alloy, with about 80% nickel and 20% iron content.Invented in 1914 by physicist Gustav Elmen at Bell Telephone Laboratories, [1] it is notable for its very high magnetic permeability, which makes it useful as a magnetic core material in electrical and electronic equipment, and also in magnetic shielding to block magnetic fields.
