The material is high-quality, high-purity aluminum, an original product from a pure solid plate. In terms of electrical resistance, aluminum ranks after silver, copper, and gold, exhibiting excellent electrical conductivity. The resistance values of gold and aluminum are almost the same. Aluminum's resistance is about 1.5 times that of copper. Since aluminum is lighter than copper, it conducts more than twice as much electricity as copper when compared by the same weight. "Doesn't aluminum not conduct electricity??" It conducts electricity because it's a metal. Aluminum is an element, so it won't conduct electricity if it has impurities, surface treatments, anodizing, or Alpina treatment. Aluminum is also used inside capacitors. ~Accessories & Specs~ Part Number: 4TBU Four M6 holes are provided. Not tapped. *The mounting part also has M6 holes.
