Copper clad steel, aluminum

  • 11-Feb-2009 03:24 EST

In addition to aluminum and brass conductors, Leoni Cable produces copper clad steel and copper clad aluminum materials. The firm's copper clad steel consists of a core of homogeneous steel surrounded by a continuous cladding of copper. The material is used for coaxial cables and low current and signal cables. Benefits of the material over copper conductors include higher mechanical strength due to steel core, 10% material weight reduction, smaller package size, and reduction of cross section of up to four gauge sizes. Compared to steel conductors, it provides better corrosion resistance and lower resistance. The company's copper clad aluminum is a conductor material composed of an inner aluminum core and an outer sleeve of copper bonded to the core. The grade is called CCA 10%, meaning that it contains 10% copper by volume. Applications include large cross-section cables such as battery cables. Benefits of copper clad aluminum over copper conductors are a higher flexibility and 63% material weight reduction. Compared to aluminum conductors, it provides better corrosion resistance, lower resistance, better solderability, and higher strength.
