Abstract

"Nichrome wire is a high resistance alloy, and is not appreciably effected in its resistance by changes of temperature to which it may be subjected in practice. This was shown by the low temperature coefficient obtained. Nichrome does not deteriorate by heating, as shown by torsion-tests after current has been passed through wire. German-Silver however, becomes brittle. Nichrome in a moist atmosphere corrodes rapidly, but in a relatively dry atmosphere, and heated red hot, no signs of oxidation or corrosion could be seen. By all results obtained as to strength, resistance, etc., Nichrome is superior to German-Silver as a resistance wire" – Conclusions, p. 19.
