Metal casting materials & alloys we work with

At Milson, we cast a range of metals including iron, steel, aluminum, and zinc. Each material is selected for its mechanical, environmental, and operational properties — from structural strength and wear resistance to corrosion protection and durability.

    Casting alloys tailored to your part and process

    Our metallurgists help you match the right alloy to your performance goals — balancing strength, weight, corrosion resistance, and cost. Every melt is verified for chemistry and properties, ensuring repeatable results at scale.

    Ductile iron

    High strength, toughness, and fatigue resistance. Performs well in load-bearing parts such as hubs, mounts, and heavy equipment components.

    Ductile iron
    White iron

    Extremely hard and abrasion-resistant. Suitable for wear parts in mining, materials handling, and other abrasive environments.

    White iron
    Austempered ductile iron (ADI)

    Combines high strength and toughness with good machinability. Often chosen for parts that need both wear resistance and fatigue performance.

    ADI
    Gray iron

    A cost-effective choice with good compressive strength and machinability. Commonly used in housings, brackets, and general-purpose components.

    Gray iron
    Steels

    Strong, versatile, and cost-effective for structural and mechanical parts. Used in heavy-duty applications where toughness and durability are critical.

    Steels
    Stainless steel

    Resistant to corrosion and heat, with excellent mechanical strength. Ideal for critical components in demanding environments.

    Stainless steel
    Aluminum alloys

    Lightweight, corrosion-resistant, and versatile. Suitable for housings, covers, and thin-walled components where weight reduction matters.

    Aluminum alloys
    Zinc alloys (including ZA grades)

    Strong, impact-resistant, and excellent for thin-wall castings. Provides fine detail and dimensional stability in high-volume production.
