Judging the quality of small-sized aluminum flat wire requires comprehensive evaluation from multiple aspects, including appearance quality, dimensional accuracy, performance indicators and production process. The following are specific evaluation methods and key points:<\/p>\n

\n

1. Appearance quality<\/strong><\/h3>\n

Inspection method<\/strong><\/h4>\n
    \n
  • Surface finish<\/strong>: The surface of the aluminum flat wire should be smooth without scratches, bubbles, burrs, cracks or obvious oxidation spots.<\/li>\n
  • Color uniformity<\/strong>: The surface color should be consistent without color difference or mottled phenomenon.<\/li>\n
  • Coating or passivation film<\/strong>(if any): The coating should be uniform without flaking, peeling or pinholes.<\/li>\n<\/ul>\n

    Quality requirements<\/strong><\/h4>\n
      \n
    • High-quality aluminum flat wire should have good surface treatment, especially when used in electrical or decorative occasions, the requirements are higher.<\/li>\n
    • Surface defects such as scratches or burrs may affect subsequent use, especially in conductive and insulating applications.<\/li>\n<\/ul>\n
      \n

      2. Dimensional accuracy<\/strong><\/h3>\n

      Inspection method<\/strong><\/h4>\n
        \n
      • Measuring Width and Thickness<\/strong>: Use high-precision measuring tools (such as micrometers or calipers) to detect the actual size of the aluminum flat wire.<\/li>\n
      • Straightness inspection<\/strong>: Check the linearity of the aluminum flat wire by visual inspection or using tools to ensure there is no warping or bending.<\/li>\n<\/ul>\n

        Quality requirements<\/strong><\/h4>\n
          \n
        • The dimensional tolerance should comply with industry standards or customer requirements. Usually the thickness tolerance is controlled within \u00b10.01mm and the width tolerance is controlled within \u00b10.05mm.<\/li>\n
        • The surface of high-precision products should be smooth and without obvious ripples.<\/li>\n<\/ul>\n
          \n

          3. Performance indicators<\/strong><\/h3>\n

          Conductive properties<\/strong><\/h4>\n
            \n
          • Inspection method<\/strong>: Measure the resistance value with a resistivity tester to ensure it meets the material specification (e.g. Aluminum 1350 usually has a higher conductivity than 61% IACS).<\/li>\n
          • Quality requirements<\/strong>: The lower the resistivity, the better the conductivity and the more suitable it is for electrical purposes.<\/li>\n<\/ul>\n

            Mechanical properties<\/strong><\/h4>\n
              \n
            • tensile strength<\/strong>: The strength of the aluminum flat wire is tested by a tensile testing machine.<\/li>\n
            • Elongation<\/strong>\uff1aTest the plastic deformation ability of aluminum flat wire during stretching. Too low elongation may cause the product to break easily.<\/li>\n
            • Quality requirements<\/strong>:\n
                \n
              • Tensile strength and elongation should meet industry standards, and the specific values vary depending on the material (such as pure aluminum or aluminum alloy).<\/li>\n
              • Too low strength or insufficient elongation may result in a shortened service life.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                Corrosion resistance<\/strong><\/h4>\n
                  \n
                • Inspection method<\/strong>\uff1aThe corrosion resistance of aluminum flat wire is tested by salt spray test or chemical corrosion test.<\/li>\n
                • Quality requirements<\/strong>: The surface of high-quality aluminum flat wire should have good anti-oxidation and corrosion resistance.<\/li>\n<\/ul>\n
