SiC additive to Aluminium / Aluminum

I am a foundry / sculpture student in Chicago who is about to cast some components in Aluminium at our school foundry.
I have been looking for information about SiC strengtheners that can
be added to Al, but have had little luck in finding out how to use the materials in a foundry, ie. finding information about handling the material / adding it to metal / health and safety issues.
Can anyone help me on these three points?

SiC strengtheners are of two types, whiskers of SiC and fibers of SiC.
The sad news, for you, is that they aren't "strengtheners" that you can stir into the melt like you can add additives to oils or gasoline. So, your proposed application is outside of current state of the art.
There is some limited introduction to metal matrix composites (aluminum would be the metal matrix and SiC would be the composite reinforcement) in the web page below: /
Do a Google search on "SiC aluminum metal matrix composites" or "Sic/Al composites" or other combinations.
It isn't just melting and mixing.
You might also find useful information at the site below on metallurgy in general....
And you can go to DWA Composites who started work in the SiC reinforced Aluminum about 25 years ago. /

homogeneously blended and vacuum-hot-pressed into commercial scale billets as large as 1,000 lbs. DRA billets are transformed into an almost limitless range of wrought products using conventional extrusion, rolling, and forging metalworking techniques.

business. As the first company to achieve market success with series production of commercial and military aerospace components, DWA has the longest and most progressive presence in the the DRA industry. Our dedication to DRA technology and problem solving has enabled our customers to realize significant benefits for their businesses.
Those few words sort of summarize the type of technology needed to stick the Sic inside the Aluminum in a useful way... and it isn't mixing in the molten state for castings.
Good luck with your metal casting sculpture.
