Soft Drawn Copper Wire

Bare copper wire, also known as bare copper wire, is a type of wire that is made from pure copper and has no coating, varnish, or insulating material on its surface. It has a smooth and shiny copper finish. In terms of its physical properties, bare copper wire is soft and exhibits exceptional electrical conductivity.

Bare copper wire serves as the fundamental range of wire and cable products available. It encompasses various applications, both as conductive wires for cables and as constituents employed in motors, electrical appliances, transformers, and other equipment.

Various shapes of bare copper wires can be obtained by processing them according to specific requirements. These shapes include flat wires, round wires, and different types of wires. Additionally, by combining multiple bare copper wires, it is possible to create various stranded wires and multi-stranded wires.

Copper, an extraordinary metal, possesses a variety of exceptional properties. Renowned for its ductility, thermal conductivity, electrical conductivity, and diamagnetism, copper stands out among its counterparts. This remarkable metal exhibits impressive characteristics such as toughness, softness, and malleability, presenting itself in a captivating purple-red hue with a dazzling shine. Often referred to simply as copper, it boasts the ability to be drawn into incredibly thin filaments that can reach astonishing lengths of up to 3,000 meters. Furthermore, it can be effortlessly pressed into sheets of almost transparent copper foil, covering an area of over 10 square meters. In terms of electrical and thermal conductivity, pure copper ranks second only to silver, while remaining significantly more affordable. With its strikingly similar appearance to gold, copper emanates an unmistakable allure. In a hydrated state, copper ions exhibit a captivating blue coloration. It is essential to note, however, that metallic copper does possess slight toxicity due to its limited solubility. Nevertheless, when copper undergoes specific processing techniques, its toxicity diminishes significantly.

Copper is an essential metal that has a remarkable affinity with humans. It plays a vital role in various industries, including electrical, machinery manufacturing, construction, and defense. As a non-ferrous metal, it is the second most widely used material after aluminum in China. The power industry is one of the significant beneficiaries of copper. Copper is widely used in power transmission, wire and cable, transformers, busbars, switches, connectors, and plug-in components. The motor manufacturing industry also relies heavily on copper for stator, rotor, shaft head, and hollow wire fabrication. Communication cables and residential electrical wiring also require copper conductors in large quantities.

Copper wires that are left untreated can undergo processing and find diverse applications across multiple industries. These industries include those related to cables, ultra-high voltage cables, communication cables, marine cables, automotive wires, photovoltaics, electronics, electromechanical, and various other fields.

The physical properties of copper are: copper is a fuchsia metal with a density of 8.92 grams per cubic centimeter. The melting point is 1083.4±0.2°C, and the boiling point is 2567°C. Has good ductility. Good thermal and electrical conductivity. The valency is usually +2, but also +1 (trivalent copper only appears in a few unstable compounds, such as potassium cuprate KCuO2). Flame color: green.

Bare copper wires must be produced and inspected according to the standards of GB/T 3953 "Electrical Round Copper Wire" and GB/T 4909 "Test Methods for Bare Wires".

After the bare copper wire is produced, it must be packaged, stored, handled and transported in strict accordance with customer and industry standards to ensure that the product is free from moisture and damage.
