Properties of copper wire
Due to the small cross-sectional area of the copper wire, it has a high level of electrical conductivity. The material is easily processed. Copper successfully copes with temperature changes and work in extreme conditions. In some cases, copper is irreplaceable!
In addition, healing properties are attributed to the metal. It is used to make jewelry and jewelry.
Fields of application of copper wire
Copper wire is widely used in electrical engineering, mechanical engineering, instrument construction, serves as asemi-finished product for the manufacture of springs and hardware, elements of current-conducting structures. That is, where a strong, plastic material with high electrical conductivity is required. Welding wire is indispensable when welding thin metal sheets. It is used in microelectronics, in working with silicon crystals, in microwelding using the thermocompression method, etc.(//tractor-service.com)
In addition, the noble color of copper and the malleability of the metal made the wire a favorite material for decorative designs and jewelry.
Types of copper wire
Copper wire differs in its purpose. There is wire for rivets, electrotechnical wire, for the electrovacuum industry, and the most in-demand welding wire.
The product is made of M1 and M2 copper. The difference in the content of pure copper affects the electrical conductivity. Marking MM means that the wire is soft, MT - hard. Also, the wire is made of oxygen-free copper and covered with enamel.
Copper wire has different cross-sections, different states of the metal surface and has different mechanical characteristics.
