• Copper-Clad Aluminum Wire (CCA) is a conductive wire consisting of an aluminum core covered with a thin layer of copper, also known as CCA wire. It combines the lightness and cheapness of aluminum with the good conductive properties of copper. Nyob rau hauv lub suab suab, occwire yog feem ntau siv nyob rau hauv cov suab hluav taws xob thiab hais lus cable thiab kuj tuaj yeem muab cov kev sib kis tau zoo thiab tsim nyog rau kev sib kis mus ntev. This makes it a common conductive material in audio equipment.
