Applications
Brass ASTM B584 C86200 is used for gears, bushings, cams and other mechanically loaded cast parts. Documented applications also include marine propellers, valve stems, structural hardware and wood-pulp pressing-die components. Other cast components used in this material family include lever arms and mechanical-contact and transmission parts.
Applications include industrial machinery, heavy equipment and selected marine mechanical components. Grade-specific distinctions between light-duty gears and slow-moving, heavily loaded bearings must be retained; lubrication and mating surfaces remain relevant.
