(U.S. Patent Off.) 4 July 18/1 Driver-Harris Company, Harrison, N.J...Nichrome. For alloys of nickel, chromium, and iron in the form of wire, ribbon, strip, [etc.]. 1937Jrnl. Brit. Interplanetary Soc. IV. 7 The nozzles were machined from nichrome steel rod, threaded at the lower end so that they could be screwed into the exhaust end of the combustion chamber. 1947J. C. Rich Materials & Methods of Sculpture ii. 46 For low-temperature firing, electric kilns equipped with nichrome wire heating elements are very efficient. 1950Jrnl. R. Aeronaut. Soc. LIV. 20/1 For general purposes, the wire used in strain gauges is a straightforward cupro-nickel, or nickel-chrome alloy, such as Eureka, Brightray, Nichrome. 1951Trade Marks Jrnl. 7 Mar. 228/1 ‘Nichrome’... Unwrought and partly wrought alloys composed mainly of nickel-chromium; and rods, tubes, bars, wire, sheets and pellets, all being goods..made from alloys composed mainly of nickel-chromium. British Driver-Harris Company Limited,..Manchester,..manufacturers. 1964S. H. Avner Introd. Physical Metallurgy xii. 387 Some nominal compositions are 80Ni-20Cr (Chromel A, Nichrome V, and others) used as electric heating elements for household appliances and industrial furnaces; 60Ni-16Cr-24Fe (Chromel C, Nichrome, and others) used as electrical heating elements for toasters..and hot-water heaters. 1968E. R. Petty Physical Metall. Engin. Materials xiii. 276 There are two main groups of heater wire, one based on 80% nickel–20% chromium (Nichrome) with or without amounts of iron, and the other based on ferritic chromium steels... The former alloy is well known as the basis of the Nimonic high temperature alloys. |
