"Metal ceramic composite material with rigidity exceeding that of cast iron due to the lightness of aluminum" Aluminum is light but bends. Iron does not bend but is heavy. This is a new material that solves the designer's dilemma. In addition to excellent specific rigidity, its outstanding thermal properties of low thermal expansion and high thermal conductivity make it suitable for movable stages. The adoption of MMC is progressing in high-speed moving parts of mountings and machine tools. It meets diverse needs through gravity casting, low-pressure casting, and die casting methods.
