drát

Drát is a flexible, elongated strand of metal manufactured for wide-ranging uses. It is typically produced by drawing metal through a sequence of dies to reduce its cross-sectional area and achieve a uniform diameter. Depending on material and coatings, drát can be bare or insulated, and may be used as a single conductor or as part of more complex forms such as wire rope.

Common materials include copper, aluminum, and steel. Copper wire offers high electrical conductivity and ductility, making it the standard for electrical and electronic applications. Aluminum wire is lighter and less expensive but has lower conductivity per weight and different mechanical properties. Steel wire provides high tensile strength for mechanical applications, such as fencing or reinforcement in composites. Insulation or protective coatings—such as PVC, polyethylene, or enamel—are applied to suit electrical, thermal, or environmental requirements. Wires are rated by diameter, cross-sectional area, insulation thickness, temperature, and voltage.

Forms and standards: Bare wires are often measured in millimeters or square millimeters of cross section, while some regions use the American Wire Gauge (AWG). Wire rope or cable consists of multiple strands twisted around a core to enhance strength and flexibility. Additional processing includes annealing to increase ductility and coatings to reduce corrosion or improve wear resistance.

Applications: Electrical wiring and telecommunications, construction and infrastructure, fencing, cable assemblies, wire rope for lifting and rigging, as well as craft, jewelry, and various mechanical components. The term drát covers a broad family of products unified by the property of being a thin, elongated metal strand designed to transmit force, electricity, or information.
