Replacing 100 of these with aluminum washers results in a total saving of 62 grams. You get this by multiplying the 0.94 grams times the ratio of aluminum to steel density (I used iron, actually), which is 2.70/7.87. The weight saved per washer is 0.62 grams, or approximately 2.19 ounces. For all that effort, you save about as much as you would by taking a ballpoint pen out of your pocket before takeoff.
