Standard Specification for Aluminum Bronze Rod, Bar, and Shapes
This specification establishes the requirements for rods, bars, and shapes of aluminum bronze with Copper Alloy UNS Nos. C61300, C61400, C61900, C62300, C62400, C63000, C63020, C63200, C64200, and C64210. Products shall be produced in tempers HR50, M10, M20, M30, O20, O25, O30, O32, TQ30, TQ50 and TQ55. Products shall be tested and shall conform to dimensional (mass, diameter, length, thickness, straightness, and edge contour), mechanical (tensile and yield strength, Rockwell hardness, and elongation), and chemical composition requirements. Products should also meet requirements under mercurous nitrate test, ammonia test, and piston finish.
C63000
C63000 is a copper alloy with aluminum as the main alloying metal, adding strength and corrosion resistance. It is used for various industrial, marine and plumbing applications
ASTM B150: C63000 (AMS4640) is one of the most commonly used American grades of nickel aluminium bronze and contains around 10% aluminium, 5% nickel and 3% iron.
B150 C63000 offers an array of properties including high strength and hardness, excellent resistance to wear, shock and abrasion. Another major benefit of this alloy is its ability to offer a high retention of its mechanical properties at elevated temperatures. C63000 / AMS 4640 is readily hot worked and offers a good machinability.
The C63000 (AMS4640) can also offer additional properties including good erosion, corrosion and cavitation resistance in seawater, as well as resistance to dilute sulphuric, hydrochloric and non-oxidising acids.

ASTM B150 UNS C63000 / AMS4640 is one of the most commonly used American grades of nickel aluminium bronze. Containing around 10% aluminium, 5% nickel and 3% iron the alloy offers an inherent high strength and hardness combined with a very good toughness and an excellent resistance to wear, shock and abrasion.
The C63000 / AMS4640 also offers a very good corrosion, erosion and cavitation resistance in seawater and brackish water together with a good resistance to dilute sulphuric, hydrochloric and non-oxidising acids. It also has a very good galling resistance and also offers a high retention of mechanical properties at elevated temperatures.
C63000 Aluminium bronze offers excellent corrosion resistance and has been used in many applications.
