Abstract
A high-strength low-thermal-expansion alloy consisting of, by weight, 0.06 to 0.50% C, 25 to 65% in total of one or both of 65% or less Co and less than 30% Ni, and balance of Fe as a main component, other optional elements and unavoidable impurities, and having a primary phase of austenite phase and martensite phase induced by working. A wire is made from the alloy.
