Nickel-iron base alloy characterized by controlled thermal expansion coefficient and inflection temperature and by desirable high strength in age-hardened condition has composition specially restricted to overcome detrimental sensitivity to stress-concentrating geometries and aid resistance to long-enduring stress in heated oxidizing atmospheres. The alloy contains, by weight, 34% to 55.3% nickel, up to 25.2% cobalt, 1% to 2% titanium, 1.5% to 5.5% of columbium plus 1/2 the weight percent of any tantalum, up to 1% chromium, not more than 0.2% aluminum and the balance essentially iron.
