A recent discussion in r.c.m. about cutting aluminum with
a circular saw prompts these pictures.  

Shown is 3" thick AL cut with a carbide blade in a DeWalt
circular saw.  Two passes and total depth is about 1.750.
The material is being sliced and diced for meat tenderizer
mallet heads, a freshman project in our school shop.
