Small size copper strip<\/a>, especially in high-precision, electronics, photovoltaic and other precision industries, it is often necessary to select high-quality materials to ensure the high performance and reliability of the product. As a common copper material, red copper (or pure copper) is an ideal choice for manufacturing small-sized copper foils, such as capacitor copper strips. The main reasons are as follows:<\/p>\n

1. Excellent electrical conductivity<\/strong><\/p>\n

Red copper is a form of copper with a higher purity (copper content above 99.9%) and has extremely low resistivity, so it has very good conductivity. In the application of capacitor copper strips, especially in electrical connections, conductive strips and welding strips, excellent conductivity is essential. Using red copper to make copper strips can maximize the efficiency and stability of current transmission and reduce power loss and heat accumulation.<\/p>\n

2. Good ductility and processability<\/strong><\/p>\n

Copper has excellent ductility and can maintain high machinability even in very thin specifications (such as 0.05mm, 0.1mm). This makes it easy to make very thin and uniform copper strips through rolling, stretching and other processes, and can complete complex forming processes without breaking. For capacitor copper strips, ductility and machinability are very critical, especially in applications that require precise dimensions and high surface quality.<\/p>\n

3. Corrosion resistance<\/strong><\/p>\n

Copper exhibits extremely high corrosion resistance in most environments. Although a natural oxide film may form on the surface of copper under certain conditions, this oxide film is very stable and can effectively protect the interior of the copper from further oxidation, thus preventing the quality of the copper strip from deteriorating during long-term use. For capacitor copper strips, especially when used in high humidity or heavily polluted environments, the corrosion resistance of copper is particularly important.<\/p>\n
