Applications
Brass ASTM B584 C83450 is used for water-pump parts, low-pressure valve bodies and waterworks valve trim. Other documented applications include electrical hardware, boat hardware and plumbing fittings. Other cast components used in this material family include 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.
