Precision Brass Ball Bearing Solid Beads Copper Lndustry Solid Ball 0.9mm-80mm

We primarily use C36000 free-cutting brass (60% Cu, 3% Pb, balance Zn) for its excellent machinability. For lead-free requirements, we offer C46400 naval brass (60% Cu, 39% Zn, 1% Sn), which meets NSF/ANSI 61 standards for potable water systems.

Our C46400 naval brass balls are specifically formulated for marine use, offering superior resistance to dezincification in saltwater. They're widely used in boat fittings, offshore valves, and desalination equipment with 5-10x longer lifespan than standard brass.

Absolutely! The 28% IACS conductivity makes them ideal for sliding electrical contacts. The self-lubricating properties of brass reduce contact wear, and the non-sparking characteristic enhances safety in high-current applications.

Micro-balls (0.9mm-5mm) maintain ±0.005mm tolerance, achieved through precision grinding after forming. These ultra-precise miniature brass balls are perfect for medical devices and precision instruments requiring tight clearances.

Yes! We provide an optional clear chromate conversion coating that delays tarnishing by 12-18 months in normal conditions. For decorative applications, we also offer lacquered finishes that maintain the bright gold appearance indefinitely.
