For copper wires an 8 mm copper rod (5/16″ in USA) is used as raw material, which is drawn through drawing dies to the required bare wire dimension in several stages.  Magnet wire is copper wire with a thin layer of insulation, and is used in a variety of applications including transformers, wound coils, motors, solenoids, etc.

Magnet Wire for EV mainly uses enameled flat wire during the degree of 180—240. 

CDA101, CDA102, and CDA110 Copper have excellent electrical and thermal conductivity, operating efficiency and corrosion resistance. 

Our magnet wire collection includes enameled wire, polyurethane wire, litz wire, and polyamide-imide wire, which are best suited to a range of applications depending on temperature requirements. 

What size is magnet wire?We're proud to provide magnet wire from 14 AWG to 44 AWG. What is Magnet Wire? Magnet wire is the term used to describe copper wire coated with an insulating jacket. This type of wire is used in electromagnets, transformers, Tesla coils, speakers, inductors, guitar pickups, and motors.

What is bare copper wire?The bare copper wire is annealed and softened, then painted and baked for many times. The conductor shall be copper wire, oxygen-free and low-oxygen copper wire with smooth surface, roundness, uniform quality and no defects as specified in the specified standard.

Bare Copper Wire Applications:
Industrial Wiring: Such thick bare copper wires are commonly used in industrial settings for power distribution and grounding purposes.

Electrical Infrastructure: In electrical substations, power generation plants, and transmission lines, large diameter bare copper conductors might be used to ensure efficient power transmission and grounding.

Earthing/Grounding: Thick bare copper wires are used in earthing or grounding systems to dissipate electrical charges safely into the ground, protecting equipment and personnel from electrical hazards.

Bus Bars: These wires can be used as bus bars in electrical panels and distribution boards to distribute electrical power within a building or facility.

Heavy Current Applications: Equipment that requires high current flow, such as large motors or heavy machinery, might utilize such thick copper conductors.

Electromagnets: For applications like industrial electromagnets, where high currents create strong magnetic fields, thick copper wires are essential to ensure the necessary current-carrying capacity.

Research and Development: In laboratory setups, large-diameter bare copper wires might be used for custom experimental setups involving high currents.

Bare Copper Wire Advantages:
Conductivity: Copper's excellent conductivity ensures minimal energy loss during power transmission.

Durability: Copper is highly durable and resistant to corrosion, which contributes to the longevity of the wire.

What is high purity copper magnet wire?This is an unalloyed, high purity copper magnet wire that has excellent forming and brazing characteristics, as well as resistance to hydrogen embrittlement at elevated temperatures. It has good solderability and corrosion resistance, and may be used in any high current application.
