Normally ¥2980, now ¥2555!! This is a new, unused item, but it's a prototype made at a customer's request. It has 10 M6 holes on the top and M8 holes on the bottom. The bolts in the image are also included. The material is high-quality, high-purity aluminum, an original product made from a solid flat plate. 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. "Doesn't aluminum 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 treatment, anodizing, or Alpina treatment. Aluminum is also used inside capacitors. ~Included Items & Specs~ Part Number: Prototype 10 holes are M6 specification. Not tapped. *BT mounting holes are M8 holes. This is made on the premise of being used exclusively for grounding in an earthing tune. 10 holes processed on the top. As this is an original processed product, please understand that there may be processing scratches, minor scratches, slight dimensional errors, and distortions. ^^; We do not accept price negotiations.
