Fluidity of ferrous material is low so ferrous material is poured by top gating. Because in bottom gating there is chance of defects like misrun and coldshut due to less fluidity(requires more time to flow or travel).
So high melting point material like ferrous material have low fluidity & low melting point materials like Al, Cu, Zn have high fluidity so these are poured by bottom gating system.
