ALUMINUM BRASS ALLOYS AND BRONZES
This category of alloys typically offers high strength, as well a good corrosion resistance. These popular metals form many cast products.
Widely used in casting, extrusions and hot forging (and sometimes even in cold forming), nickel silver alloys have gained acclaim because they usually accept a high polish. Metal parts composed of these alloys may display sleek, almost satin-like finishes, for instance. Most metal parts consisting of nickel silver alloys perform decorative roles, although some do display other advantages, such as heightened wear resistance, corrosion resistance and strength. Properties of the individual alloys vary, based upon metal composition.
NAVAL BRASSES AND BRONZES
Alloys classified as naval brasses or bronzes display excellent corrosion resistance properties. Used in both brass castings and extrusions, these alloys function well in rugged maritime environments. Shipbuilders often rely upon naval brass alloys in cabin components, for instance.
Used in both brass castings and extrusions, DZR (“dezincification resistant”) brass alloys function well in underwater environments. These metals resist the loss of zinc.
Usually more expensive than alloys containing lead, lead-free brasses perform an important role in many municipal water systems in the USA since the passage of the Safe Drinking Water Act in 1974. They frequently form plumbing components, including pipes, faucets and other fixtures.
With good hot forging properties, high tensile brass alloys typically demonstrate high strength, plus excellent resistance to corrosion and wear. Manufacturers use these alloys in forged fasteners, pump parts and rods, pump valves, and valve spindles.
ARCHITECTURAL BRASS AND BRONZE ALLOYs
Brass alloys and bronze alloys appear frequently in decorative items used in architectural construction. For instance, parts made from this attractive category of metal alloys often form moldings, door and window frames, door handles, elevator sills and other modern building decor items.
