Applications
Brass ASTM B584 C83800 is used for air, gas and water fittings, valves, pump fixtures and bushings. Other documented applications include electrical switches and railway catenary fittings. Other cast components used in this material family include valve bodies, 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.
