can you use the tableware? because that's the only dwemer metal i know of that isn't actively trying to fry anything that moves.
The stuff you want to look for is either just lying around as scrap or sometimes in enemy loot (spiders, spheres, etc.), particularly these three items: Bent Dwemer Scrap Metal, Large Dwemer Plate Metal, and Small Dwemer Plate Metal. Each of these only weighs two lbs. but will produce three dwarven ingots (thus the best weight/value ratio). In any given dwemer ruin, you may very well find more of these than you can either reasonably, or at least care to, lug out.
