Not necessarily. You have to think of what kinds of loads you will get in each direction. Saying aluminum will work doesn't mean much as it will work with the right shape, but if designed poorly it will bend as will most metals.
I just despise of steel because of it's weight, that does not mean it isn't right for your application. I would wait for someone with some experience making a brace to chime in with the magnitude of loads you will be looking at.
