Treatment with CompactMag® alloy gives very reliable results when producing compacted graphite iron.

Producing compacted graphite iron by either undertreating with MgFeSi or making a good ductile iron and then adding titanium are unreliable methods with narrow production parameters. Treatment with CompactMag® alloy gives you far more reliable results, with broader production windows and without the addition of harmful titanium.

• Specially designed alloy for structure control in compacted graphite iron (CGI)
• Cost-effective alternative to titanium providing better machinability and a minimum of slag and dross
• Contains carefully balanced Mg, Ca, and RE for optimum CGI production
• The high Rare Earth content ensures a minimum of section sensitivity in the CGI microstructure
• Recommended for low sulfur base irons and can be used in both ladle and in-the-mold treatment processes
• CompactMag® alloy allows for thoroughly mixing the CGI returns with ductile returns without causing any harmful interactions
