Ni90Cr10 austeniticum chromium nickel-alaymus (NiCr alloy) usui temperaturae usque ad 1200°C (2190°F).Admixtum proprium est magnae resistentiae, bonae oxidationis resistentiae et valde bonae formae stabilitatis.Habet bonum ductilem ad usum et optimam copulam.
Ni90Cr10 pro electricis calefactionibus elementis in domo adhibitis et fornacibus industrialibus adhibetur.Applicatae typicae sunt planae ferreae, machinae ferreae, calentium aquae, corona plastica moritur, ferrum solidans, elementa metalla vaginata et cartridge elementa.
Ob adhaesionem optimae proprietates superficiei oxydi, Ni90C10 praestantiorem vitam offert servituti comparatae ad chromium auctorum nickel-almatorum.

CHROMEL vs ALUMEL in oxidizatione, iners vel sicco atmosphaerae reducendo adhibetur.Patefacio vacuum finitis brevibus temporibus.Defendi debet ab atmosphaeris sulphureis et oxydizantibus marginalibus.Certa et accurata in calidis temperaturis. Chromel: Chromel est stannum extimationis 90% nickel et 10% chromium.Ponitur in fabricandis conductoribus positivorum ANSI Type E et Type K thermocouplis, machinas ad temperaturam metiendam duobus diversis conductoribus constans.
