MCC (also known as KS) is a zinc based alloy ideal for the production of strong decorative components by centrifugal casting and easy to cast close to finished form and redundant tooling can be remelted and re-used providing it is not contaminated with other materials, particularly lead or solder.

MCC is also an alloy with excelent fluidity. However dimensional stability and retention of mechanical properties over a period of years or when subjected to higher service temperature are not as good as zinc alloys for pressure casting as Mazak 3, Mazak 5 or Mazak 8.
