The main differences between copper clad aluminum wire and pure copper wire<\/strong><\/h3>\n

1. Color<\/strong><\/h4>\n
    \n
  • Copper wire<\/strong>: Purple<\/li>\n
  • Copper clad aluminum wire<\/strong>: Off-white<\/li>\n<\/ul>\n

    2. Density and weight<\/strong><\/h4>\n
      \n
    • Pure copper wire<\/strong>: High density and heavy.<\/li>\n
    • Copper clad aluminum wire<\/strong>: Lower density and lighter weight.\n
        \n
      • Under the same length and specifications,Copper clad aluminum wire<\/strong>Compared with pure copper wire, it is lighter and easier to transport and install.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

        3. Mechanical properties<\/strong><\/h4>\n
          \n
        • strength<\/strong>: The strength of pure copper conductor is higher than that of copper-clad aluminum conductor.Not easy to break<\/strong>.<\/li>\n
        • Elongation<\/strong>: Pure copper has a high elongation and a strong ability to return to its original shape after being subjected to force.<\/li>\n
        • Softness<\/strong>: Copper-clad aluminum is softer than pure copper, and the conductor is more flexible and easier to bend.Copper clad aluminum wire<\/strong>Easy to bendfracture<\/strong>In contrast, pure copper wireAnti-fatigue<\/strong>It has stronger performance and can recover after deformation.<\/li>\n<\/ul>\n

          4. Electrical performance<\/strong><\/h4>\n
            \n
          • Electrical conductivity<\/strong>\uff1aBecause aluminum has poor conductivity, copper-clad aluminum conductorsDC resistance<\/strong>Larger than pure copper.\n
              \n
            • When the frequency exceeds 5MHz, theAC resistance attenuation<\/strong>Same effect.<\/li>\n
            • In high frequency applications (such asCoaxial Cable<\/strong>), copper-clad aluminum conductors and pure copper conductors behave similarly, and the copper-clad aluminum conductorReturn loss<\/strong>Might be better.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
