The material is high-quality, high-purity aluminum, an original product processed from pure solid flat plates. In terms of electrical resistance alone, aluminum ranks after 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. "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. Part number: 3LTBC Features three M6 holes with ball bearings. Not tapped. *The mounting part also has M6 holes. Includes cap SUS bolts, nuts x 3 Includes BT mounting flange nut x 1 *With OFC ring Despite its compact size, it allows for the attachment of up to 6 points of 22SQ barrels. Recommended for those who want to minimize battery mounting space. This product is made with the assumption that it will be used exclusively for grounding in an earthing tune. A standard 3-hole original processed product. As this is an original processed product, please consider processing scratches, minor scratches, slight dimensional errors, and distortions as part of its charm ^^; We do not accept price negotiations.
