Enameled Copper clad aluminum (ECCA) is a consisting of an aluminum core clad with copper,the wire has high frequency elect. Copper clad aluminum is widely used in applications requiring the conductivity of copper while retaining much of the weight advantages of aluminum. ECCA offers the inherent characteristics of aluminium while the copper cladding provides greater conduction of current and the ease of soldering of copper. CCA wire is used for electrical contact material and conductors. it is an electrical conductor which has an outer sleeve of copper metallurgically bonded to a solid core aluminum conductor. The combination of these two metals make it uniquely suited to many electrical applications.
1. Compared with pure copper enameled wire, copper clad aluminum enameled wire has obvious advantages:
The density of copper clad aluminum wire is 1/3 of that of pure copper wire of the same wire diameter, which is very effective in reducing the weight of cables and coils. In the field of audio coils, product performance has been significantly improved.
2. Good DC resistivity
The DC resistivity of copper clad aluminum wire is about 1.5 times that of pure copper wire; when the resistance value is the same, its wire diameter is about 1.2 times that of pure copper wire, while the weight of copper clad aluminum wire is only 1/2 of that of pure copper wire. .
3. Good brazing performance
Copper-clad aluminum wire is concentrically coated with a layer of pure copper, so it has the same solderability as pure copper wire and does not require special treatment like aluminum wire.
4. Low cost
Compared with pure copper enameled wire, copper-clad aluminum wire can reduce production costs by 30%-50% in some applications.
Enameled CCA wire is widely used in different electrical applications requiring the conductivity of copper while retaining much of the weight advantages of aluminum, If you have any need, welcome to visit xinyu-enameledwire, XINYU is a leading manufacturer and supplier
