Product overview

Saguenay Foundry produces Compacted Graphite Iron castings from 200 lb to 12,000 lb (100 kg to 5500 kg). CGI is also known as vermicular iron. For more information on CGI’s properties, please go to our Technical Center.

 

Custom CGI

We pour CGI parts for a variety of applications requiring high thermal shock resistance. We presently use the ASTM A-842 standard for this type of iron.

 

CGI Rapid Prototyping

Compacted Graphite Iron is still marginally used. If you think this could be the right material and need to test it at affordable cost, our rapid prototyping techniques could be you’re most cost-effective option.
