Nickel Aluminum Bronze Alloy

Aluminum bronze aluminum bronzes are a family of copper based alloys containing aluminum as the principle alloying element.

Nickel aluminum bronze alloy.

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. It s used where higher mechanical properties are required. 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. These nickel aluminum bronze alloys are used for bushings bearings wear plates and hydraulic valve components.

As such it is the purpose of this publication to provide an engineering overview of the properties of the. Increasing the aluminum content of bronze results in higher strength. 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. Nickel aluminum bronze nab is a metallic alloy that is widely used for ship valves and propellers among other marine applications.

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. 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. Concast produces c95400 c95500 and c95900 in standard sizes of rounds tubes and rectangles. It s used in equipment for the energy markets in aircraft marine and a host of other industrial applications.

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. All of the aluminum bronzes can be heat treated further increasing tensile strengths. Aluminum bronze is the highest strength standard copper based alloy. Other alloying agents such as iron nickel.

Aluminum in conjunction with iron and nickel in c95800 acts as a strengthener in these alloys. 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. Nickel aluminum bronze alloys c63000 ams 4640 c95510 ams 4880 c63020 ams 4590 and c95520 ams 4881 are used in landing gear bushings.
