Foundry casting metals 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 gears, crankshafts, and heavy equipment components.

    Austempered ductile iron (ADI)

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

    Steels

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

    Explore steel castings
    Stainless steel

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