Metallilanka

Metallilanka refers to a slender, flexible strand of metal used in a wide range of industrial, scientific, and artistic applications. It is produced by drawing metal through a sequence of dies to reduce its cross-sectional area, which increases strength and hardness. Common metals for metallilanka include steel (including stainless varieties), copper, aluminum, and various alloys. The diameter can vary from less than a millimeter to several millimeters, with thinner wires often used in electronics and precision instruments.

The properties of metallilanka depend on the material and treatment. Typical attributes include high tensile strength and ductility, good fatigue resistance, and varying levels of electrical or thermal conductivity. Copper wires conduct electricity well, while steel wires excel in stiffness and load-bearing capacity. Corrosion resistance can be enhanced through coatings such as galvanization or enamel, and heat-treatments like annealing can adjust hardness and elasticity.

Production and processing involve drawing metal through progressively smaller dies, sometimes followed by annealing to relieve work hardening. Wires may be coated or plated for surface protection. In many cases, multiple strands are twisted together to form wire rope or cables, which improves flexibility and strength for lifting, pulling, or structural applications.

Applications are diverse. Electrical wiring and electronics utilize conductive metals, while construction, fencing, and cable systems rely on tensile wires and ropes. Wires are also used in springs, fasteners, and mechanical components, as well as in jewelry and decorative arts for their aesthetic properties and workability.

Standards and safety considerations govern metallilanka production and use. Manufacturers adhere to international or regional standards regarding diameter tolerances, coatings, and performance. Handling requires attention to sharp edges and proper storage to prevent damage or corrosion.
