What is C63000 C63000 Nickel Aluminum Bronze Aluminum Bronze Bar ?
C63000, also known as Nickel Aluminum Bronze (NAB), is a high-performance copper alloy engineered for demanding industrial environments. Thanks to its unique combination of aluminum, nickel and iron, this alloy offers exceptional mechanical strength, excellent wear resistance and outstanding corrosion resistance, making it one of the most reliable copper alloys for critical applications.
Compared to traditional bronze and brass alloys, C63000 performs exceptionally well under high loads, elevated temperatures and corrosive environments such as seawater.
Chemical Composition
Typical chemical composition:
Element | Content (%) |
Copper (Cu) | Balance |
Aluminum (Al) | 9.0 – 11.0 |
Nickel (Ni) | 4.0 – 5.5 |
Iron (Fe) | 3.0 – 5.0 |
Manganese (Mn) | Max. 1.5 |
The combination of nickel and iron significantly increases the alloy's strength while maintaining excellent corrosion resistance.
Key Properties of C63000
Very high tensile and yield strength
Excellent wear and galling resistance
Outstanding corrosion resistance in marine environments

Why is C63000 Preferred for Mold Making?
For mold manufacturers, C63000 provides an excellent balance between strength and thermal conductivity.
Compared to tool steels, it dissipates heat much faster, reducing production cycle times while maintaining excellent wear resistance. This contributes to longer mold life and improved productivity.
Machinability
Although C63000 is considerably stronger than standard bronze alloys, it can be successfully machined using appropriate cutting tools and machining parameters.
Precision CNC machining allows manufacturers to produce complex components with tight tolerances while preserving the alloy's mechanical properties.
Corrosion Resistance
One of the biggest advantages of C63000 is its excellent resistance to:
Seawater
Salt spray
Industrial atmospheres
Fresh water
Mild acids
Alkaline solutions
This makes it one of the preferred materials for marine, offshore and chemical processing industries.
Heat Treatment
C63000 can be supplied in various heat-treated conditions depending on the required mechanical properties. Proper heat treatment improves hardness, tensile strength and wear resistance while maintaining good toughness.
