C85800 copper wire is a leaded nickel-brass alloy renowned for its exceptional free-machining characteristics. The intentional addition of lead allows it to be machined rapidly and efficiently, producing small, breakable chips and a superior surface finish. This property makes it a preferred material for high-volume production of intricate components on automatic screw machines.
Beyond its machinability, this alloy offers a valuable combination of good corrosion resistance and higher strength compared to standard brass alloys. The inclusion of nickel enhances its durability against wear and attack from various environments, such as freshwater and the atmosphere. Consequently, C85800 copper wire is widely used in the manufacture of durable hardware, fittings, and gears that require both complex machining and reliable service life.
