| CCA Wire | Copper clad aluminum wire (CCAW) is a bimetallic compound consisting of an aluminum core and a concentric copper cladding. This combination of copper and aluminum provides a wire with optimum properties of both metals. The aluminum core reduces the weight of the CCAW to almost that of pure aluminum wire. Furthermore, the copper cladding increases the conductivity and provides good solderability. | 1.Low density allows coil weight reduction 2.Easy soldering due to copper cladding 3.Higher conductivity compared to aluminum | 1.Voice coils (e.g. in Headphone, Headset, ...) 2.VCM coils for HDD actuator 3.Optical pickup coils 4.Loudspeakers 5.Others |
