Grey cast iron Ductile cast iron Burr, tolerance Burr, tolerance Burr, tolerance Burr, tolerance. Machinability of Gray Cast Iron versus Compacted Graphite Iron To study the differences in machinability between gray cast iron and CGI, machining tests were conducted on a Bridgeport V2XT machine using a standard water based metalworking fluid. Annealed cast ductile iron can be bent, twisted or deformed without fracturing. Grey cast iron will melt at 1600 degrees Celsius, at which point it transitions quickly from a solid to a fully liquid state. Research and Technical Director 2 As these photomicrographs show, Ductile Iron differs from Gray Iron in that its graphite is spheroidal, or nodular, instead of the flake form found in Gray Iron. It's more ductile in comparison to white cast iron. Properties Good under compression.
