10% SiC Addition to Aluminum

  • The aluminum with 10% SiC addition meets the minimum requirements for modulus and strength, compared to the unreinforced C 355-T6.

  • The fluidity of the aluminum with 10% SiC addition exceed the minimum fluidity requirements at the 775C pouring temperature.
              --  It is approximately 10% more fluid
                  than the Al-20% SiC alloy.

  • But  the specific modulus (modulus divided by the density) for the 10% SiC addition is 11% lower than the specific modulus for the 20% SiC addition (127.7 x 10^6 vs 143.1 x 10^6 in)
