I searched the internet and found a Silicon-Aluminum phase diagram.
Here is the URL:
http://www2.umist.ac.uk/material/research/intmic/phase/alsidiag.htm The
eutectic composition is approximately 87 wt% Al and the eutectic
temperature is 660C.

Li, These materials don't truly alloy, hence there is no eutectic, The
"alloys" are really finely divided mixtures, and manufactured using an
atomization process.
