Technical features and scope of the DIN EN 12166 standard
The European standard DIN EN 12166 regulates the technical delivery conditions, dimensional tolerances, chemical composition, and mechanical properties of wire made from copper and a wide range of copper alloys. This regulatory document covers products intended for both general technical use and high-load assemblies, such as the production of precision springs and critical fasteners.
The manufacturing technology for wire according to the DIN EN 12166 standard includes cold drawing, hot rolling, or extrusion methods, which allows for achieving an optimal material microstructure for subsequent machining. EV Group China products comply with all standard requirements regarding surface quality, diameter limit deviations, and the stability of physical and mechanical characteristics within a batch.
