I. Product Introduction
C14415 is a high-performance copper-tin alloy engineered specifically for high-current transmission systems. By adding a precise amount of tin, it achieves an excellent balance of >85% IACS conductivity, enhanced mechanical strength, elevated softening resistance, and improved oxidation resistance – all without compromising electrical performance.
Unlike pure copper, C14415 maintains its structural integrity after brazing and under prolonged thermal cycling, significantly reducing the risk of contact resistance increase or connection failure caused by softening.
Primary applications: EV battery busbars, high-voltage connectors, and charging infrastructure components – delivering the “high conductivity + thermal stability + long-term durability” that the new energy vehicle industry demands.
II. Core Technical Specifications
KINMACHI enforces strict full-process control over the key physical and chemical parameters of C14415, ensuring every batch meets the stringent requirements of EV battery busbars, high-voltage connectors.
