ABSTRACT:
There are provided a low expansion alloy having a high corrosion resistance which consists essentially of 25-50% by weight of Ni, 1-25% by weight of Cu and optionally up to 20% by weight of Cr and the balance of essentially Fe with a small amount of impurities, and a corrosion resistant bimetal formed by applying together a low expansion alloy plate which consists essentially of 25-50% by weight of Ni, 1-25% by weight of Cu and optionally up to 20% by weight of Cr and the balance of essentially Fe, and a corrosion resistant alloy plate which has a linear expansion coefficient larger than that of said low expansion alloy plate by 5.times.10.sup.-6 .degree. C.
