F4TBU-C Earthing Terminal Block, Flexible Type, 4-Hole Type The material is high-quality, high-purity aluminum, originally processed from a solid aluminum plate. Aluminum, when compared only by electrical resistance, has excellent electrical conductivity, following silver, 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. ~Accessories & Specifications~ Part Number: F4TBU-C 4-hole M6 specification with ball screws. Not tapped. *The mounting part is also an M6 hole. Bolts and nuts x 4 each BT mounting flange nuts x 2 This product is manufactured on the premise of being used exclusively for grounding in earthing tuning. Since the battery mounting part and the plate are independent, it can be installed in various styles. *Recommended mounting terminals: 8 gauge to 4 gauge Because it is an original processed product, please understand that there may be processing scratches, scuffs, slight dimensional errors, and distortions. ^^; The image is a sample.
