Quality casting
Gray iron
Gray iron is one of the most popular material in the industry. At Fusium, we deal with gray iron every day. We can cast parts in gray iron (or lamellar iron) weighing from 200 lb to 16,000 lb (100 kg to 7250 kg).
Custom Grey Iron
We’ve mastered the art of the gray iron production line thanks to our efficient, quick, and accurate techniques. We cast this alloy every day and we provide excellent results that meet international standards.
All of our castings are in compliance with our clients’ specifications or established international standards (e.g. ASTM A-48, A-319 or DIN EN-1561).
High-Temperature Resistant Gray Iron
We know how important it is for you to obtain high-quality parts with a long lifespan. With Fusium, you’ll obtain the quantity of gray iron you want at an affordable cost.
We regularly pour low-alloy gray iron parts, such as the standard ASTM A-319. Our decades of experience working with the primary aluminum smelters and foundries assures the most durable and longest work cycles for your castings.
Gray Iron Rapid Prototyping
If you need a low volume of gray iron castings, our rapid prototyping capabilities could benefit you. Simply specify us the quantity required and we will advise how to proceed in order to save as much as possible.
