Cast ironis anironalloy containing 2 wt.% – 4 wt.% carbon, 1 wt.% – 3 wt.% silicon and smaller amounts of minor elements [1]. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content.Cast ironcan also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before beingcast
