Self bonding copper wire refers to a wire with self-adhesive properties formed by coating the outer layer of insulating paint film with a layer of self-adhesive paint. Compared with ordinary enameled copper wire, self bonding wire not only has its own wire diameter specification It is small and does not need to use auxiliary materials such as skeleton during the winding process, which can greatly reduce the weight and volume of the winding, and is more suitable for micro and small electronic components and electronic products.
Conductor Material:
Copper:
Hot air self bonding wire used 2.6mm Oxygen-free copper rod, alloy grade TU1, copper content ≥99.95%, the resistivity≤ 0.01724Ωmm²/m(20ºC), we use copper from peru to manufacture oxygen-free copper. Only high-quality raw materials can ensure the performance of self bonding copper wire . The copper rod manufacturing equipment of the South Line helps us to produce efficiently. Coupled with China's perfect industrial chain, raw materials are continuously shipped to the factory.
Copper clad aluminum wire:
The smaller the vibration of the voice coil, the better the control, so the smaller the quality of the bondable magnet wire , the better. The copper-clad aluminum wire just meets this requirement, with light weight and excellent signal transmission. Copper clad aluminum wire adopts advanced cladding welding technology to form a metallurgical bond between copper and aluminum and become an inseparable whole.
