What’s the different of ductile iron , gray iron and malleable cast iron ?
1. The characteristic of ductile iron is very tough, graphite is in the form of a ball.
2.The feature of gray iron is very brittle , graphite is in the form of strip.
3.The particularity of malleable cast iron is graphite is a group of flocculent tiles.
So the ductile iron is hardest , malleable cast iron is harder than gray iron.
