Nickel Aluminum Bronze Alloy

The nickel aluminium bronze alloys are fairly complex materials and during manufacture require good control of the metal structure by attention to composition and heat treatment.

Nickel aluminum bronze alloy.

Nickel aluminum bronze nab is a metallic alloy that is widely used for ship valves and propellers among other marine applications. C63000 nickel aluminum bronze ams 4640 is an extruded or forged wrought aluminum bronze that contains nickel and is alloyed for exceptional strength and toughness. A variety of aluminium bronzes of differing compositions have found industrial use with most ranging from 5 to 11 aluminium by weight the remaining mass being copper. Their strength is similar to that of medium carbon steel and they possess excellent corrosion resistance though aluminum bronzes possess many other valuable characteristics.

While displaying a good combination of corrosion resistance and strength nab is still prone to different forms of corrosion such as stagnant sea water corrosion selective phase corrosion and cavitation erosion. Aluminum bronze aluminum bronzes are a family of copper based alloys containing aluminum as the principle alloying element. Aluminum bronze is the highest strength standard copper based alloy. Nickel aluminum bronze alloys contain 5 to 11 percent aluminum as well as additions of iron and nickel for strength.

Aluminium bronze is a type of bronze in which aluminium is the main alloying metal added to copper in contrast to standard bronze copper and tin or brass copper and zinc. Other alloying agents such as iron nickel. Nickel aluminum bronze alloys c63000 ams 4640 c95510 ams 4880 c63020 ams 4590 and c95520 ams 4881 are used in landing gear bushings. Increasing the aluminum content of bronze results in higher strength.

As such it is the purpose of this publication to provide an engineering overview of the properties of the. Tracing its roots back to the original development of nickel aluminium bronze copper alloys is an established and integrated manufacturing company. The excellent bearing properties combined with the corrosion resistance in salt conditions during deicing of run ways in the winter make these alloys ideal for this application. Carries an extensive inventory of nickel aluminum bronze c63000 ams 4640 and the c95500 nickel aluminum bronze bar c630 is a special high strength aluminum bronze used in applications involving heavy loads friction and abrasive wear and corrosion.

Having developed unique material processing technology and with a team comprising some of the worlds pre eminent non ferrous metallurgists copper alloys has a track record in the production of. All of the aluminum bronzes can be heat treated further increasing tensile strengths. It s used in equipment for the energy markets in aircraft marine and a host of other industrial applications. These nickel aluminum bronze alloys are used for bushings bearings wear plates and hydraulic valve components.
