Automotive Cable Upgrades Driven by ISO 6722 | |
Description: In the field of automotive battery connections, the ISO 6722 standard is driving continuous technological innovation. Copper core conductors, thanks to their high-purity copper, achieve a conductivity of up to 98% IACS, enabling efficient and cost-effective current transmission in typical vehicle interior environments. However, in humid and high-temperature environments, they are susceptible to oxidation, which can affect performance. Production and Processing Technology: Tinned copper is coated with a 2-5μm tin layer on the copper core. While this slightly reduces conductivity to 94% IACS, it significantly improves corrosion resistance. According to the ASTM B117 salt spray test, after 1000 hours of exposure to a 5% NaCl solution, the resistivity fluctuation remains within 5%. Tinned copper effectively resists oxidation in harsh environments like the engine compartment, ensuring stable power transmission. To meet the stringent dimensional, performance, and test method requirements of the ISO 6722 standard, both have been continuously upgraded. Copper conductors utilize optimized processing techniques to reduce impurities and further enhance conductivity. Tinned copper utilizes innovative tinning processes, such as low-temperature tinning and nano-composite coating technology. This improves corrosion resistance while minimizing the impact on conductivity, providing a solid foundation for the safe and efficient operation of automotive battery systems.
