Die Casting Vs. Sand Casting | What's the Difference?

Oct 20, 2015· Because of the downtime that occurs — up to 5 minutes per casting — sand casting is best applied to parts that are lower quantity. The materials used in this process also typically lead to less detail in the final products, which usually require more secondary operations than die casting. The image above shows multiple sand casting molds.

Iron and Oxygen | Chemdemos

Iron combusts in oxygen to form various iron oxides, mainly iron(III) oxide: 4 Fe (s) + 3 O 2 (g) ==> 2 Fe 2 O 3 (s) Iron in its usual bulk solid form will only burn when in pure oxygen with when a great deal of heat is supplied.This is what a cutting torch does. As we can see in this demo, however, when iron is subdivided finely it burns readily enough in air.
