The material is high-quality, high-purity aluminum, an original product processed from pure solid flat plates. In terms of electrical resistance alone, aluminum follows silver, copper, and gold, and has excellent electrical conductivity, second only to copper and gold. 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. "I thought aluminum didn't 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: F4TBC Kai Tapped with 4-hole M6 specifications.
