Cast Iron

Ductile Iron

Gray Iron

Cast Iron is a Ferrous Alloy that consists of mainly Iron with the addition of Carbon (approx. 2%-3.5%) and Silicon (approx. 1%-3%).  Other elements can be added as well to change the microstructure and physical properties of the metal.  The Carbon in Cast Iron cools as Graphite that separates from the solution of molten metal during the cooling process.  Cast Iron can be produced with Nodular (Ductile Iron) or Flake (Gray Iron) Graphite .  Both have their advantages and disadvantages, depending on the application or  mechanical property needs.  Please contact EPI-MTG for more information or assistance you need with the metallurgical examination of your Cast Iron material.

Metallurgical Polishing and Chemical Etching

Metallurgical polishing is a tricky business.  EPI MTG is well versed in the techniques to polish many different materials.  We have polished metals that are Iron, Nickel, and Aluminum based.  We also have experience with PCD and a variety of carbides.  We can also provide chemical and electrolytic etching of the sample after polished to a fine finish.  We have the ability to etch most all alloys from using Nital on carbon steel to molten sodium hydroxide on silicon nitride.  EPI MTG hopes to work with you in the future with your metallurgical polishing and etching needs.
