Applications
Brass ASTM B584 C86300 is used for heavily loaded, slow-speed bearings, bridge pins, bushings and high-strength machine parts. Additional applications include hydraulic-cylinder parts, large valve stems, cams and wood-pulp forming-die components. Other cast components used in this material family include gears, 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.
