Sealed Iron-Nickel-Cobalt 4J44 alloy strip with permanent expansion
Precision alloy, is a metal material with special physical properties (such as magnetic, electrical, thermal and other properties).Most precision alloys are based on ferrous metals, while a few are based on nonferrous metals.It usually includes magnetic alloys (see magnetic materials), elastic alloys, expansion alloys, thermobimetallic, electrical alloys, hydrogen storage alloys (see hydrogen storage materials), shape memory alloys, magnetostrictive alloys (see magnetostrictive materials), and so on.
