Aperam FeNi 70 Controlled Expansion Alloys Iron-Nickel Alloys
Categories: Metal; Ferrous Metal

Material Notes: This alloy (also called Hytemco) presents the particularity to have a very high temperature coefficient. At 300°C for example, its resistivity has already increased of 2.65 times its value when cold. This particularity makes it very interesting for the use of emergent heaters because its power will fall when hot. It is in this respect auto regulating. Typical application is electric blanket.
