Gray iron or ductile iron? Compare graphite structure, ASTM A48 classes and A536 grades, strength, damping, cost, and applications to specify the right casting.

Trumbull Foundry and Alloy offers a unique, in-house service that can create high-quality, custom metal castings from an existing physical part, even when no drawings, models, or original tooling are available. This "something from nothing" approach saves customers significant time, money, and stress, providing a fast, affordable, and flexible solution for replacing obsolete or impossible-to-find metal components.

Gray iron is one of the most widely used casting metals, and for good reason. Known for its excellent machinability, vibration damping, and cost-effectiveness, gray iron has been the workhorse behind countless industrial applications for over a century.

Not all metals are created equal, and not every job needs the same material. Some projects demand strength, others corrosion resistance, and some a balance of weight and durability. Material choice affects performance, cost, and lifespan. At Trumbull, our expertise of casting metals helps customers get it right the first time.
