Why 15% Copper Clad Aluminium (CCA) ?
Our CCAQY(F)-2/240 features a 15% copper volume fraction — significantly higher than standard 10% CCA wires. This premium composition delivers superior electrical conductivity, enhanced solderability, and better corrosion resistance while maintaining excellent weight savings over pure copper.
|
Higher Conductivity ~65-72% IACS — outperforming standard 10% CCA (62-68%) and far exceeding pure aluminium. |
~50% Lighter than Copper Density ~4.2 g/cm³ — reduces total coil weight while maintaining excellent mechanical integrity. |
Superior Solderability Thicker copper outer layer ensures reliable soldering — no special fluxes or techniques required. |
Why 15% Volume Ratio? Our 15% copper volume fraction provides a thicker copper outer layer compared to standard 10% CCA. This results in: ① Higher conductivity (65-72% vs 62-68% IACS), ② Better heat dissipation, ③ Enhanced corrosion resistance, and ④ More reliable solder joints — making it the preferred choice for demanding applications.
