Overview


F1 Manganin Constantan copper Alloys Round Wire 6J8 is engineered for harsh industrial environments, combining enhanced manganese-copper (Mn-Cu) ratios for superior mechanical strength, corrosion resistance, and stable conductivity. With optimized resistivity (0.02-0.03 Ω·mm²/m) and heat tolerance (continuous use at 350°C), it is ideal for precision electronics, high-temperature sensors, and chemical processing equipment. ISO 9001 certified, 6J8 wire guarantees long-term reliability and eco-compliance.
