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 (VDM® Alloy 29-18, VDM® Alloy 42, VDM® Ni 42, VDM® Alloy 51 und VDM® Alloy 52 – formerly known as Pernifer alloys) 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 VDM® MAG 50 (Magnifer 50) and VDM® MAG 53 (Magnifer 53) as the most important representatives. The second group is constituted by high-nickel alloys, notably represented by VDM® MAG 7904 (Magnifer 7904) and VDM® MAG 75 (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, VDM® Alloy HT 60 (Cronifer II), VDM® Alloy HT 30 (Cronifer III), VDM® Alloy 40 B (Cronifer 40 B) und VDM® Aluchrom W are used especially for the starting and braking resistors in electric drive systems.
