General Info About 5251 Aluminum Sheet

Though this grade is non-heat treatable, it has great ductility and is easily cold worked in the annealed condition. It has high fatigue strength, good weldability, and very good corrosion resistance, especially in marine atmospheres. It is available in the O, H22, H24, and H26 tempers.

More Details About 5251 Aluminum Sheet

  • Advantages/Disadvantages

    This aluminum is excellent in marine environments due to its corrosion resistance.  Other advantages include excellent weldability and workability. Machinability varies depending on the specific temper.

  • Industries

    It is often used in the aircraft, marine, automotive, and food processing industries.

  • Applications

    Common applications for this grade include small marine craft, architecture, aircraft parts, general sheet metal work, auto paneling, and food processing equipment, components, and systems.

  • Machining

    Machinability for this grade depends on the temper. The harder the alloy, the easier it is to machine. For the softer tempers, including the annealed condition and H32, machinability is poor.

  • Welding

    This grade has excellent weldability.

  • Heat Treatment

    This grade is not heat treatable.

Frequently Asked Questions

  • What is the difference between 5052 and 5251?

    ANSWER:

    Though these two grades are similar in composition, they are not always interchangeable in function. One striking difference is the yield strength. It is significantly lower in 5251.

  • Why is 5251 good for marine environments?

    ANSWER:

    This grade tolerates a range of atmospheric environments because of its magnesium content. The percent of magnesium in this alloy is low enough that it withstands stress corrosion cracking. Its excellent corrosion resistance makes it suitable for marine applications.

  • Which 5251 temper has the highest tensile strength?

    ANSWER:

    5251-H36 and 5251-H38 have the highest tensile strengths.
