I am trying to find a substitute for ductile iron. I need to find a metal that has similar ductility as ductile iron, but, is a tad lighter. I have tried ZA12, and although the casting came back beautifully, the metal edges create burrs. I am designing professional horseshoes and need to add a little more design than is permitted with the weight of ductile iron (.28 pounds per cubic inch). When the ZA12 hit the steel stake it created sharp burrs. Is there the possibility that there a plating that would eliminate the burrs? Would electroless nickel be a possibility?
Thanks
