I have an idea for a project that requires cutting a rectangle out of A356 Aluminum foam. Its not really foam, more like aluminum casting with a bunch of air pockets in it that are pretty large. I have read most of the information on milling aluminum and it all seems to be focused on 6061 but nothing talks about A356. I also have found very little information about its hardness, McMaster-Carr does not have a rating for it. Probably due to it having a foam like structure. Any suggestions on how to proceed? I don't mind experimenting but welding bit after bit gets old and the aluminum foam is not cheap. Thanks.
