CCAM (Copper clad Aluminum and Magnesium wire) Adopted international advanced welding technology in the production of coated Jing tong above grade level by 99.99% copper, copper layer of high density, good conductivity Copper clad aluminum and magnesium core line among the metallurgical copper layer evenly distributed along the circumferential direction and vertical, concentricity good. B566-93 various product standards and technical specifications in accordance with “ASTM standard E: SJ/T11223-2000as copper wire” acceptance. 1. CCAM wire integrates the beneficial properties of good conductivity of copper & light weight of aluminum in a single wire.2. The density of CCAm is about 40% of that of copper. Its length is 2.4 times of copper in the same weight & diameter. These factors reduce the raw material cost for cable manufacturers.3. CCAM has the high tensile strength it makes the customer un-interrupted in the using.4. Environment friendly, CCAM saves the copper resources & its production is a nonpolluting process.The physical characteristic of copper clad aluminum wire:Product SpecCopper layer(volume ratio%)Copper layer(Content ratio%)Density(g/cm3)Length ComparisonResistivity(Ωmm2/m)Conductivity(%IACS)CCAM-15%15403.75±5%2.40:1≤0.0320≥53CCA-15%15403.63±5%2.45:1≤0.02676≥64CCA-10%10303.32±5%2.70:1≤0.02750≥60Pure Copper Wire99.9899.988.891.00:1≤0.01724100
