Applications
Brass ASTM B584 C86700 is used for moderate-duty gears, cams, bearings and lever arms, as well as valve stems and fittings. Other documented uses include brackets, fasteners and marine hardware. Other cast components used in this material family include bushings 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.
