Power transmission needs nickel and iron

Electronic components play an important role in almost every area of our private and working lives. For instance, in entertainment, in telecommunications and in the automotive industry. Examples of the latter include engine control systems and other automotive components. To ensure sealing integrity for these components, the thermal expansion behaviour of the metal alloys must be adjusted to that of the various glass grades and ceramic materials. Outokumpu VDM offers wires in nickel-iron alloys (Pernifer 2918, Pernifer 40, Pernifer 42, Pernifer 50 and Pernifer 51) with this kind of controlled expansion behaviour.

In electronic engineering, the soft magnetic Magnifers are virtually indispensable and have been used successfully for many years. They can be subdivided into two main groups. The first group comprises the alloys with a medium nickel content, with Magnifer 50 and Magnifer 53 as the most important representatives. The second group is constituted by high-nickel alloys, notably represented by Magnifer 7904 and Magnifer 75. These alloys are chiefly used for stamped and formed parts, toroidal strip wound cores and as strip for core laminations, current measuring modules and electrovalves.

Among the austenitic nickel-(iron)-chromium alloys and the ferritic iron-chromium-aluminium alloys there are heating conductors, which are processed into speciality wires for use in practically all areas of the electrical industry. Metallic heating conductors are used wherever electric current is converted into heat. As resistance alloys, Cronifer II, Cronifer III, Cronifer 40 B and Aluchrom W are used especially for the starting and braking resistors in electric drive systems.
