HCCA 2KS-AH 0.04mm Self Bonding Enameled Copper Wire
Both pure copper and copper clad with aluminum can both be used as
conductor for wire when there’ s different needs of tone quality.
Study shows that higher purity of copper is beneficial to improve
sound quality. It can be seen that pure 4N (99.99%) copper is
usually adopted in the market. Copper coated aluminum conductor
self-adhesive wire conforms to requirement of improving utilization
rate of wire without affecting sound quality (high-frequency voice
coil). Bond coat of the wire can be activated by two methods of hot
air and solvent. This wire is preferred by most customers due to
its convenient process to shape and low cost. Diameter of this wire
is relatively thin.
