Compacted Graphite Iron

The Case Metal Processing Laboratory currently holds a SinterCast license, enabling controlled production of compacted graphite iron (CGI). Current research efforts are investigating the effect of sulfur additions on the size of the process window leading to vermicular graphite formation.

Poor machinability currently limits conversion from grey iron to CGI due to increased costs. Research has been conducted to determine the effect of various material variables on tool wear during machining. The lab has the capability to cast plates with various geometries for machinability testing and benchmarking.
