    Product Details

    We maintain a complete inventory of aerospace-grade and commercial-grade aluminum alloy materials to ensure the best performance and cost suitability:

    6061-T6 Most Versatile

    The most versatile structural alloy, offering excellent machinability, weldability, and corrosion resistance. Suitable for most mechanical components, tooling fixtures, and enclosures.

    7075-T6 Ultra High Strength

    An ultra-high-strength aluminum alloy with strength comparable to many steels. An ideal choice for aerospace, high-performance sporting goods, and critical load-bearing structures.

    5052-H32 Marine Grade

    Offers excellent corrosion resistance (especially in marine environments) and formability. Commonly used for ship and vehicle trim, and electronic enclosures.

    2024-T3/T4 Aerospace

    Provides good fatigue strength and strength-to-weight ratio. Widely used in aircraft structural components, truck wheels, and other high-strength applications.

    MIC-6 / Cast Aluminum Tooling Plate Precision

    A precision-ground, pre-hardened plate with stress-free internal structure, ideal for precision substrates, fixtures, and molds.

    Frequently Asked Questions
    QWhat is the difference between 6061-T6 and 7075-T6 aluminum alloys?
    6061-T6 is the most versatile general-purpose alloy, known for its excellent machinability, weldability, and corrosion resistance. 7075-T6, on the other hand, offers significantly higher strength — comparable to many steels — making it better suited for aerospace, high-performance, and critical load-bearing applications where maximum strength is required.
    QWhich aluminum alloy is best for marine or outdoor environments?
    5052-H32 is the top choice for marine and outdoor environments due to its exceptional corrosion resistance, particularly in saltwater conditions. It is widely used in ship components, vehicle trim, and electronic enclosures exposed to harsh environments.
    QWhen should I choose 2024-T3/T4 over other aluminum alloys?
    2024-T3/T4 is the preferred choice when high fatigue strength and a superior strength-to-weight ratio are critical requirements. It is commonly selected for aircraft structural components, truck wheels, and other demanding high-strength applications where cyclic loading is a concern.
    QWhat makes MIC-6 Cast Aluminum Tooling Plate different from standard aluminum plate?
    MIC-6 is a precision-ground, pre-hardened cast aluminum plate specifically engineered with a stress-free internal structure. Unlike standard rolled aluminum plates, MIC-6 offers superior dimensional stability and flatness, making it ideal for precision substrates, fixtures, jigs, and molds where tight tolerances are essential.
    QDo you stock both aerospace-grade and commercial-grade aluminum alloys?
    Yes. We maintain a complete inventory of both aerospace-grade and commercial-grade aluminum alloy materials. This ensures that customers can select the most appropriate material based on their specific performance requirements and budget considerations.
    QWhich aluminum alloy is most suitable for general mechanical components and enclosures?
    6061-T6 is the most recommended alloy for general mechanical components, tooling fixtures, and enclosures. Its well-balanced combination of machinability, weldability, corrosion resistance, and moderate strength makes it the go-to material for a wide range of everyday engineering and manufacturing applications.

    Finishes and Post-Processing Options

    The zinc alloy substrate is highly suitable for various surface treatments to enhance decoration, protection, or functionality:

    Electroplating: Such as chrome, nickel, gold, or silver plating, providing a highly decorative appearance, excellent wear and corrosion resistance. This is the most common choice.

    • Passivation or Chromate Conversion Coating:

    • Powder Coating:

    • Painting:

    • Physical Vapor Deposition (PVD):

    Design and Machining Considerations

    • Process Selection:

    • Design Considerations:

    • Material Selection:

      Zamak 3 and 5 are suitable for the vast majority of general-purpose parts requiring good appearance and strength; ZA-8 is better for wear and bearing applications; for making rapid tooling, choose specialized alloys like Kirksite.
