CuAl10Fe2 is a well-established aluminum bronze alloy and is covered by various international norms and standards that specify its composition, properties, and applications. These norms ensure uniformity and compliance for industries using this material.

Spefications

  1. Corrosion Resistance:

    • Excellent resistance to seawater corrosion and chemical exposure, particularly in chlorides and sulfides.

  2. Mechanical Strength:

    • Provides high tensile and yield strength for applications requiring durability.

  3. Wear Resistance:

    • The addition of iron improves wear resistance, making it suitable for components exposed to friction.

  4. Ductility:

    • Offers good ductility, making it suitable for forming and machining.

Applications

CuAl10Fe2 is used in various industries due to its desirable properties:

  • Marine Applications:

    • Fittings, propellers, and components exposed to seawater.

  • Industrial Applications:

    • Gears, bushings, and wear-resistant parts.

  • Chemical Processing:

    • Valves and fittings exposed to corrosive substances.

International Norms for CuAl10Fe2

1. European Standards (EN):

  • EN 1982:
    Specifies requirements for copper and copper alloys in castings. CuAl10Fe2 is listed for applications requiring corrosion resistance and mechanical strength.

  • EN 12420:
    Covers wrought copper and copper alloy products, including rods, bars, and profiles.

  • EN 12163/12167:
    Specifies requirements for wrought rods, bars, and sections made of copper alloys like CuAl10Fe2.

2. DIN Standards (Germany):

  • DIN 17665:
    Defines aluminum bronzes, including chemical composition and mechanical properties for both cast and wrought forms.

3. ISO Standards:

  • ISO 428:
    Specifies wrought aluminum bronze materials for industrial use.

  • ISO 197-4:
    Details casting properties for copper alloys, including CuAl10Fe2.

4. ASTM Standards (USA):

  • While CuAl10Fe2 itself may not have a direct equivalent, similar aluminum bronzes like C61400 or C61900 fall under:

    • ASTM B150/B150M: Wrought aluminum bronze bars, rods, and sections.

    • ASTM B148: Aluminum bronze castings.

5. UNS Designation:

  • UNS C62400: A close equivalent in the Unified Numbering System (UNS), sharing similar composition and properties.
