I have guy with 180 science or more on one guy. You can get multitude amounts out stuff. metal parts, junk, computer chips, alloys. Depending on what you dismantle has big effect. Its also random factor. Like laser rifle can give something like 1-3 metal, parts 1-3 junk, 1-3 computer chips. Some stuff give nothing like 9mm pistol. Computer chips can only come from energy weapons. Get a lot junk this way and some metal parts to. A lot of chips to if you do laser rifles. Alloys on the other hand are hard get. I got one alloy for dismantling mini gun. The expensive stuff not worth dismantling ones can give alloys it seems. One more thing to note. You can use super tool box while dismantling. Not sure how much it helps but it does. It will break after a lot times of use. But low science like 100-120 probably worth using if you going dismantle a lot.
