20% SiC Addition to Aluminum
wpe22.jpg (28082 bytes)

  • The aluminum with 20% SiC addition exceeds the minimum requirements for modulus and strength, compared to the unreinforced C 355-T6.

  • The fluidity of the aluminum with 20% SiC addition meets the minimum fluidity requirements at the 775C pouring temperature.

  • The specific modulus (modulus divided by the density) for the 20% SiC addition has the highest value (143.1 x 10^6 in) compared to values for baseline C355 and the 10% SiC-aluminum alloy.
