The material is high-quality, high-purity aluminum, an original product processed from pure solid flat plates. Comparing only electrical resistance, 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. The resistance value is about 1.5 times that of copper. Aluminum is lighter than copper, so when converted to the same amount, it conducts more than twice as much electricity as copper. "I thought aluminum didn't conduct electricity??" It conducts electricity because it's a metal. Aluminum is an element, so it will not conduct electricity if it has impurities, surface treatments, anodizing, or Alpina treatment. Aluminum is also used inside capacitors. ~Accessories & Specs~ Part Number: T3TLBUB-T8 Tapped for 2-hole M8 specifications.
