About MIC6 (Techo-Babble alert):
Mic 6® Aluminum Cast Plate is a blend of the most desirable features of many individual metals. The manufacture of this tooling plate material is the most advanced in the cast plate industry. It promotes consistency between plates and reduces the risk of disrupting material stability by entrapping stress. Its cast granular structure and stress relieving properties allow high-speed metal removal with little, if any of the distortion commonly inherent in flat-rolled metals. Advantages of cast aluminum tooling plate Mic 6® include its light weight, smooth flatness tolerance, good machining qualities, and it is free from tension, contaminants and porosity.
