kjeder

Kjeder are elongated series of interconnected links that form a chain. The term covers a wide range of objects, from industrial chains used to lift and secure loads to decorative chains worn as jewelry. In Norwegian, the plural kjeder corresponds to the English "chains," while the singular kjede refers to a single chain.

Materials and construction: Kjeder are made from metals such as steel, stainless steel, iron, copper, and aluminum; jewelry chains may use precious metals such as gold, silver, or platinum. Chains can be plated or coated, for example with rhodium to improve appearance and durability.

Common forms: Industrial chains include roller chains and leaf chains, used in power transmission and lifting. Decorative or jewelry chains include curb, Figaro, rope, box, snake, wheat, and satellite chains, each with distinct link shapes and drape. Chains may be welded at the joints or soldered closed, and many are assembled by joining individual links.

Applications and use: In industry, chains transmit mechanical power, enable lifting and securing of loads, or act as towing or anchor components. In jewelry, kjeder form the base for pendants, can influence wearability and style, and are selected for weight, flexibility, and appearance.

History: Chains have been used since ancient times for binding, lifting, and decoration. Advances in metallurgy, machining, and plating have expanded the range of materials and styles available today.
