Product Details
0.026MM SUPER THIN MAGNET WIRE ENAMELED COPPER CLAD ALUMINUM WIRE
FOR VOICE COILS
Enameled copper clad aluminum wire is a kind of enameled wire that
is made fo alumunum conductor with copper cladding.The typical
benefit is light weight, at the same length with copper wire, CCA
wire is only half the weight of copper wire, aluminum can realize
better sound resonance in high end acoustic.This product has
excellent properties of solvent resistance,mechanical property,
heat resistance, cut through testing and easy coloring,widely used
in special motors.electrial apparatus and household electrical
appliances.
FEATURES
Light weight. Only 50% of copper at the same length
Solderability
Good ductility and bending strength
High fidelity sound quality
