Abstract: An insulated electric conductor includes a flat or round wire made of one or more electrically conductive materials, the flat or round wire having an exterior surface that is free of an oxide layer; and an insulating layer adhering directly to the oxide-layer-free exterior surface to form a coating around the oxide-layer-free exterior surface, the insulating layer being made of at least one thermoplastic material which provides electrical insulation. The flat or round wire is designed to conduct an electrical current.

Abstract: In order to increase the adhesion of an insulating coating (2) to an electric conductor (1), preferably of copper or aluminum, an insulated electric conductor comprising an electric conductor (1), preferably made of copper or aluminum, with an insulating coating (2) is proposed according to the invention, wherein the insulating coating (2) either comprises at least one insulating layer (3) made of thermoplastic material, or the insulating layer (3) and a plastic-containing intermediate layer (4, 5), obtainable by a method in which the electric conductor (1) is placed under a protective gas atmosphere and is bombarded with ions of the protective gas in a gas plasma in order to remove an oxide layer formed on a surface of the electric conductor (1) and/or to increase the surface energy of the electric conductor (1), and subsequently either the at least one insulating layer (3) or, in the case that the coating (2) comprises the plastic-containing intermediate layer (4, 5), at least the plastic-contain

Abstract: A metal alloy is primarily formed of copper, nickel, magnesium and iron. The main constituents are copper and nickel. The contents of magnesium and iron are increased considerably in comparison with the prior art conventional alloys.

Abstract: A metallic composite wire has at least two metallic layers. One layer, preferably the inner layer, is a non-ferrous metal alloy. A second layer, preferably the outermost layer, consists of copper.

Abstract: A metal alloy is primarily formed of copper, nickel, magnesium and iron. The main constituents are copper and nickel. The contents of magnesium and iron are increased considerably in comparison with the prior art conventional alloys. The novel alloy has the following constituents in the following proportions (in % by mass and/or % by weight): copper (40% to 61%), nickel (35% to 45%), manganese (3.9% to 10%), iron (0.1% to 5%); and other materials, such as carbon, silicon, aluminum, magnesium, titanium, chromium, rare earths, molybdenum, and/or yttrium (at most 2% in total), with the sum of the components amounting to 100% by mass or, respectively, to 100% by weight.
