Product overview

Saguenay Foundry casts parts in gray iron (or lamellar iron) weighting from 200 lb to 16,000 lb (100 kg to 7250 kg). For more information on gray iron properties, don’t hesitate and go to our Technical Center.


Custom Gray Iron

We pour gray iron on a daily basis using a wide range of alloys to improve mechanical properties and thermal resistance. 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 regularly pour low-alloy gray iron parts, such as the standard ASTM A-319. Our decades of experience with primary aluminum processors and foundries assure our castings an improved lifetime. 


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.
