Bare Copper Wire Spools are used in situations where a great deal of flexibility is required and copper wire should be used when strength is necessary. They are widely used in circuit board connections, audio headphones & connection areas around moving joints. These types of wires are used in electric motors, coils and magnet wiring. The wire spools are highly flexible & compensate for vibration, expansion etc. As highly flexible, these wire spools can be used as connectors. Due to its high electrical & thermal conductivity, Bare Copper Wire Spools helps in electrical and mechanical industry.
