FERRO SILICON MAGNESIUM

APPLICATION

Ferro silicon magnesium offered by us produces high quality nodulising agents. These ferro silicon

magnesium find wide application in production of SG Iron & specialty grey iron castings for the

automobile industry. The use of ferro silicon magnesium also provide number of distinct advantages in

nodularisation of ductile iron.

These include:

•Higher quality castings through maximum nucleation
•Improved graphic nodularity
•Fewer as-cast carbides in thin section castings for improved machine-ability
•Reduced heat treatment costs
•Precise control of rare earth levels with single alloy addition
•Higher levels of ferrite & lower hardness for given composition and section sizes
•Greater tolerance to slightly higher level of pearlite promoting residual elements
