Applications
Brass ASTM B584 C84400 is used for low-pressure fittings, pump fixtures, valve bodies for water systems and water-meter valves. Other applications include lock hardware, heating and cooling equipment, ornamental fixtures and marine hardware. Other cast components used in this material family include pump-related parts, shaped connections and hardware and enclosure components.
Applications include plumbing, water-handling equipment, building services and industrial fluid-control assemblies. A plumbing use does not itself establish drinking-water certification or a finished component pressure rating.
