Titanium chassis?
Something struck me earlier today as I was working on my buggy: why are there no titanium chassis plates? At first I thought that maybe it would be cost-prohibitive, but then, not nearly so as a carbon-fiber piece, which requires far more labor to produce.
I realize that titanium is somewhat heavier than aluminium, but it also has a far greater strength-to-weight ratio, and so my thinking is that a conventional 3mm thick chassis in aluminium could be made out of 2mm titanium, retain the same mechanical properties of its aluminium counterpart, but probably shave off an ounce or two in the process, and possibly be more durable as well.
I'd be curious to hear what the metallurgical experts among you have to say about this idea. Is this merely foley on my part, or is this an idea with a modicum of merit?
