GENERAL INFORMATION (Not a Requirement) A.1 CHARACTERISTICS AND APPLICATIONS UNS No. Characteristics and Applications C83600 leaded red brass A general utility alloy with reasonable strength and corrosion resistance, good casting and machining properties. Typical uses: Architectural ap
42、plications, bearings, fixtures, piston rings, pump bodies, hydraulic and steam valves. This is a suitable bearing material for low speeds and loads. For use as a bearing material, see CEMS C-5. C85400 leaded yellow brass Inexpensive, good machinability and castability. Typical applications: Parts an
43、d fittings for radiators and other water cooling systems. C86300 high strength manganese bronze The following manganese bronze alloys consist of copper, manganese and iron. They are intended for use in castings where high strength and toughness are desired. These materials do not possess the same de
44、gree of corrosion resistance or bearing qualities as the aluminum bronzes. For use as a bearing material, see CEMS C-5. A higher cost alloy than C86500 but with considerably greater mechanical properties. Also has corrosion resistance and good casting properties and is used for similar applications
45、as C86500. C86500 manganese bronze Possess excellent corrosion resistant and casting properties. In certain cases can be used as a suitable substitute for malleable iron. Typical applications: Brackets, shafts, gears and structural parts. C90500 gun metal The following alloys are all of a family of
46、tin bronzes which have the general characteristics of being hard, strong, tough, wear resistant (especially with phosphorus), fairly machinable (with lead) and resistant to salt water corrosion. Has highest hardness of the standard commercial tin bronzes. Similar to C92200 with the exception of the
47、higher tin content which increases tensile strength and wear resistance C90700 phosphor gear bronze Similar to C90500 but with increased toughness and wear resistance, which permit use in gears and worm wheels where the requirements are severe.
