Difference Between Grey Cast Iron and White Cast Iron ...

Dec 11, 2015 · The differences between grey cast iron and white cast iron emerge from the composition and the color of the surface of the material after fracturing. Both of these iron casting alloys mainly contain carbon and silicon, but in different proportions. A key difference between grey cast iron and white cast iron is that after fracturing, white cast iron gives a white coloured crack surface and grey cast iron produces a grey coloured fractured surface.
