In general, yes. However, what's usually the limiting factor in rigidity in structures, especially tiny minibots, is not your material but your cross-section. "Thick enough" for both polycarbonate and aluminium is usually very close to doable, as long as your pieces are arranged and put together in a nice, rigid manner.
If you don't want to cut Tetrix aluminium, you can use various kinds of "standard" aluminium parts.
