Aluminum Bronzes are a family of copper-based alloys offering a combination of mechanical and chemical properties unmatched by any other alloy series. This feature makes the Aluminum Bronze the first choice for demanding applications. No...I'm not on an Aluminum Bronze Campaign kick BUT I love to learn about an alloy family that outshines the rest. Well at least in some areas!
So what are the attributes that makeAluminumBronzes so hot and in demand Check these out:
Excellent Strength- In fact it is similar to that of low alloy steels.
Factoid:Several common groupings of low-alloy steels, beginning with HY 80, HY 90, and HY 100 steels, are used for building ship hulls, submarines, bridges, and off-highway vehicles. These low-alloy steels contain nickel, molybdenum, and chromium, which add to the material's weldability, notch toughness, and yield strength. When welding these low-alloys steels, preheat and post heat treatments typically are not required.
Excellent Corrosion Resistance- Especially in seawater and similar environments, where the alloys often outperform many stainless steels. Aluminum bronzes can be used in environments that are far more aggressive than are tolerated by most other metals. Like many copper alloys, aluminum bronzes also resistbio foulingin both fresh and saline waters. Aluminum Bronze alloys may be considered for service with a wide variety of chemicals, particularly where is a combination of stress and erosion, but selection must take account of the anticipated temperature & other services conditions. Here is a sample of some chemicals: Acetic Acid, Ammonia (dry), Brine, Bromine (dry), Chlorine (dry), Nitrogen, Sodium Carbonate, Phosphate and much more.
C63000 (AMS 4640 - CDA 630) Nickel Aluminum Bronze alloy is an excellent choice for applications involving heavy loads, abrasive wear resistant, friction, abrasive wear and corrosion. The addition of nickel increases the alloys strength without diminishing its excellent ductility, toughness and corrosion resistance. Typical applications for C63000 nickel aluminum bronze included aircraft landing gear components, strut bearings, main pistons, trunnion bearings and similar vital components.
Typical Uses for C63000 Nickel Aluminum Bronze:
C95400 Aluminum Bronze, also known by C954, is the most popular, all purpose aluminum bronze alloy. It provides high yield and tensile strength, good ductility, weldability and exceptional resistance to wear, fatigue and deformation under shock or overload. Typical applications include bearings, gears, valve components, wearplate and wearstrip. Conforms to continuous cast specification ASTM B505 and centrifugal cast specification ASTM B271.
Typical Uses for C954 Aluminum Bronze:

|Min. %||Max. %|
|Principal Design Features||This is a high strength alloy of very good toughness. |
It is a derivative of AL 7075 alloy and the AL 7475 version is available in sheet and plate product forms
|Applications||Commonly used in the manufacture of shell casings, aircraft, and other structures|
|Machinability||Machining characteristics are very good in the annealed condition. Use of oil base lubricants for all machining operations is recommended|
|Forming||This alloy may be formed by conventional methods. |
However forming is easier in the annealed condition because in the heat treated (hardened)
condition the alloy has more springback due to its strength. Use of warming at 250 F will assist in forming, especially for spinning.
Optimum formability is with the material in the W (quenched) condition
|Welding||Not normally done to this alloy and no data on techniques available at this time|
|Heat Treatment||Heat treatment may be done|
However the parameters of the treatment are proprietary to Alcoa
Heat treat information is available from Alcoa on a non-disclosure agreement basis
