Copper coil

Product details:

Application:

Copper coils are widely used in many fields. In the electrical field, it is a key raw material for the manufacture of wires and cables. Its high conductivity is second only to silver, which can reduce power transmission losses, and its corrosion resistance can also extend the life of cables. It is also used in the production of motor windings and transformer coils to reduce heat generation and copper loss and help dissipate heat, ensuring efficient and stable operation of equipment. In the construction field, it can be used as a roof and wall decoration material, which is beautiful and weather-resistant. In the pipeline system, due to its good processability and corrosion resistance, it can ensure smooth fluid transportation. In industrial processing, heat exchange equipment such as heat exchangers and condensers can be made, and its excellent thermal conductivity can be used to improve heat exchange efficiency.

Product Features:

1. Excellent electrical and thermal conductivity

Conductive properties: Copper coil contains high-purity copper and is an excellent conductive material. Its electrical conductivity can reach a very high level, which makes it play a key role in the electronics and electrical industries. For example, in the production of circuit boards, copper coils can be used as good conductive line materials to effectively transmit current and ensure the normal operation of electronic equipment. Thermal conductivity: The thermal conductivity of copper coils is also high, which means that it can conduct heat quickly. In some equipment that needs heat dissipation, such as the windings of large transformers, copper coils can quickly dissipate heat to avoid damage to the equipment due to overheating, thereby extending the service life of the equipment.

2. Good processing performance

Strong plasticity: Copper coils have excellent plasticity. It can be processed into products of various shapes and thicknesses through cold processing methods such as cold rolling and cold bending. For example, when manufacturing shielding covers for small electronic components, copper coils can be cold bent into suitable shapes to meet the needs of shielding electromagnetic interference.

Easy to weld and connect: Copper coils can be connected by a variety of welding methods, such as gas welding, arc welding, etc. The joints of the copper coil after welding have good conductivity and mechanical properties. This easy-to-connect feature makes it very convenient to manufacture large conductive structures or complex electronic devices.

3. Excellent ductility

The copper coil has excellent ductility. It can be stretched into very thin copper foil and used in packaging, decoration and other fields. For example, in food packaging, the stretched copper foil can be used as a barrier layer to effectively prevent oxygen, moisture and other damage to food, and can also use its good thermal conductivity for heating packaging.

4. Good chemical stability

Under normal conditions, the chemical properties of copper coils are relatively stable. An oxide film will form on its surface, which can prevent further oxidation of the internal copper to a certain extent. However, in some special chemical environments, such as those containing acidic substances or salt spray, copper coils may corrode and corresponding protective measures need to be taken.

5. Beautiful appearance characteristics

Unique color: The copper coil presents a typical purple-red color, which is beautiful and has a high degree of recognition. In the fields of architectural decoration, artistic creation, etc., the color of copper coil can add a simple and elegant atmosphere to the works, and it is a very popular decorative material. Good surface quality: After proper processing, the surface of the copper coil can achieve a high degree of finish, which can reflect light and enhance the visual effect. And through surface treatment methods such as polishing and brushing, the copper coil can present different textures to meet different aesthetic needs.

6. Recyclability

Copper coil is a recyclable material. Due to the high recycling value of copper, the recycled copper coil can be reprocessed into new copper products through smelting and other processes. This not only helps to save resources, but also conforms to the concept of environmental protection and sustainable development.
