MMC is a High performance casting in which SiC ceramic particles are uniformly dispersed in aluminum alloy.
Lightweight ･ High rigidity=High Specific Stiffness
Density → Equivalent to aluminum : 2.8~2.9 g/cm3
Rigidity → Higher than cast iron : 125~150 GPa
Low thermal expansion ･ High thermal conductivity
Thermal expansion is equivalent to carbon steel and stainless steel
Thermal conductivity is higher than aluminum.
By casting methord
It can be replaced with the same shape as aluminum casting, or iron casting.
Manufacture of large complex shape products (500 kg, 2m×2m or more) is possible.
With our own processing machine,
We consistently handle from casting to final shape processing.
