Aluminum is a metal, hence, it is conductive<\/strong>. Not just that, it is the 4th most conductive metal alongside silver (1st), copper (2nd), and Gold (3rd).<\/p>\n\n\n\n

Unlike most metals, aluminum has a better weight-to-conductivity ratio and features in various real-life applications. The only issue with aluminum is its susceptibility to extreme heat in electrical connections.<\/p>\n\n\n\n

This guide will do more than just confirm aluminum as a conductor. It will walk you through how it conducts electricity and heat, its electrical conductivity and resistivity, and its various uses.<\/p>\n\n\n\n

Properties of Aluminum<\/h2>\n\n\n\n
    \n
  1. Aluminum is a slivery-white and non-magnetic metal.<\/li>\n\n\n\n
  2. It is malleable, ductile, hard, and readily combines with other metals to form alloys. <\/li>\n\n\n\n
  3. It is non-lustrous and with a degree of blue tint.<\/li>\n\n\n\n
  4. It has a face-centered cubic (FCC) structure, hence it is very stable.<\/li>\n\n\n\n
  5. Aluminum is resistant to corrosion due to the oxide layer present on its surface.<\/li>\n\n\n\n
  6. It has a density of 2.70 g\/cm3.<\/li>\n\n\n\n
  7. The melting point and boiling point of aluminum are 660.3\u00b0C and 2470\u00b0C respectively. <\/li>\n\n\n\n
  8. The metal is very lightweight and durable.<\/li>\n<\/ol>\n\n\n\n

    How Does Aluminum Conduct Electricity?<\/h2>\n\n\n
    \n

    Aluminum conducts electricity because it contains a sea of delocalized electrons inside it. These electrons form a lattice structure and are held together by a metallic bond<\/a>.<\/p>\n\n\n\n

    Within aluminum, a positively charged metal atom is surrounded by negative electrons that can move in any direction. However, with the introduction of an electric potential (a source of current), these negative (randomly moving) electrons start to flow in a particular order.<\/p>\n\n\n\n

    They begin to move from negative to positive terminal). This turn of events is responsible for the conductive ability of aluminum.<\/p>\n\n\n\n

    Electrical Conductivity of Aluminum<\/h2>\n\n\n\n

    Electrical conductivity is a measure of how great a material is at conducting electricity. At 20\u00b0C, the electrical conductivity of aluminum is 3.5 x 107 S\/m. <\/p>\n\n\n\n

    To calculate the electrical conductivity of aluminum, this is the formula to use:<\/p>\n\n\n\n

    \u03c3 = 1\/\u03c1<\/strong><\/p>\n\n\n\n
