Types of Nickel Alloys and their Properties

For an application that desires a metal with low thermal expansion, nickel-iron alloys are the perfect match. Nickel-iron alloys referred to as Pernifer 6 exhibit an incredibly low rate of thermal expansion which is about 1/10 that of carbon steel. It is a dimensionally stable grade of a nickel alloy. These properties make nickel-iron alloys great for precision measurement equipment. These alloys have soft magnetic properties and are thus used in devices such as transformers, inductors, and memory storage equipment.
