At twice the thickness, it can't cost less, at least not just in materials alone. The real cost savings comes from the fact that you can punch grade 2 far more easily, which I am assuming is being done. Biggest cost in a tool like the Tark, is that each one has to be waterjet cut because of the grade of titanium being used, $7 verses $1, never mind the initial tooling costs. The same thing goes for titanium V stakes, grade 5 eats up the dies, if they will even cycle. Yet another case for grade 9, it can be punched and bent almost as easily as grade 2, but is almost as strong as grade 5. Yes, it costs more, but if you use thinner material, you cut costs there, get a lighter tool, and one that is stronger. Factories(US or Chinese) may balk at this, but as a tool and die designer(with years of real world journeyman shop experience), I call BS, it can be done. I understand that everything is a compromise, but not every aspect is worth compromising. I get gigged for products that are both too light, and too heavy, not everything is ideal.
