About Alloy
2.4889 (alloy 45 TM) is chiefly used in high-temperature applications with extremely corrosive media.
With a relatively constant rate of thermal expansion to about 800°F (538°C), low expansion 45 Alloy has been used in thermostats, and its thermal expansion is similar to some alumina ceramics. High permeability 45 Alloy is a 45% nickel-iron alloy capable of exhibiting a high initial permeability and has been used predominantly in the telecommunications industry. National Electronic Alloys does not sell the High Permeability version of 45 Alloy.
