C85200 is a high-performance leaded brass wire renowned for its exceptional overall performance. Its most notable features include excellent electrical conductivity (approximately 26% that of pure copper) combined with high strength and elasticity, enabling it to withstand mechanical stress and repeated insertion and removal. More importantly, its lead content significantly improves the material’s free-machining properties, making it easy to machine into complex, precisely sized parts while effectively protecting machining tools and improving production efficiency.
For this reason, C85200 copper wire has become a popular material for the manufacture of various electrical connector components. It is widely used in the automotive, electrical, and electronics industries, often in key components such as terminal blocks, connectors, fuse clips, precision screws, and gears, offering a perfect balance of functionality, reliability, and cost-effectiveness.
