Enameled Copper Clad Aluminum (ECCA) is a clad bi-metal utilizing electrical conductor grade aluminum as its core and oxygen free copper for its outer layer. The cladding process creates a permanent continuous weld between the two metals. The composite wire is uniquely suited to electrical applications where weight and conductivity issues are critical. The copper makes up either 10% or 15% of the cross sectional area of the Winding Wire and assures excellent solderability. AC conductivity at frequencies greater than 5MHz is equal to solid copper. ECCA is manufactured in accordance with the requirements of ASTM B-566. Film Insulations are available on ECCA. See the magnet wire insulation guide for enamel options.
Enameled copper clad aluminum wire-ECCA features:
1.DC resistivity: the DC resistivity of copper clad aluminum enameled wire is 1.40-1.45 times that of the pure copper wire; for equivalent resistance value, the weight of copper- clad aluminum wire is only 1/2 that of the pure copper wire.
- Supreme solder-ability; with a coat of pure coat, Enameled copper clad aluminum wire-ECCA boasts the same braze-ability ad the pure copper wire, no need for special treatment, meanwhilen which coated with a thick copper layer to ensure that the solder-ability shall not be harmed during the scrape.
- Light weight :the density of Enameled CCA wire is only 1/2.5 that of the pure copper wire of the same diameter, which can efficiently reduce the weight of coil; the replacement of copper wire with Enameled CCA wire can realize a cost saving of more than 30%.
