The M12 Copper Flat Washer is made from high-purity copper for superior electrical conductivity and low resistance. Its precise sizing ensures tight fit and maximum contact area, minimizing overheating and ensuring stable current transmission.
Essential for conductive connections in power equipment, electrical panels, grounding systems, and high-current applications requiring safety and reliability.
Excellent Conductivity: Pure copper material facilitates efficient current flow with minimal resistance.
Overheat Prevention: Large contact area distributes current evenly for safe, stable operation.
Corrosion Resistant: Natural copper properties resist oxidation in electrical environments.
