They are copper, but I'm not sure how far you'll get with that method. Copper is soft, and remains soft. When you use a fresh washer, the copper deforms as you tighten up, making the seal. You can get away with reusing the washer a few times, as long as you clean up the surface with fine emery paper. But every time you use it, it gets thinner and wider, so takes more force to squeeze next time. Grunff's tip of the day: Screwfix sell multipacks of copper washers, which come in sooo handy. -- Grunff
