Caption: More than 800 miles of foil can be rolled from this largest aluminum ingot ever cast in a reduction plant of Reynolds Metals Company. It weighs 36,500 pounds and was cast at Reynolds plant at Troutdale, Oregon, using a special mold on Troutdale's direct chill casting unit. It measures 24 inches by 78 inches and is 17, 1/4 feet in length. Ingots 14.6 feet long are produced on a regular basis at Troutdale. After being rolled into sheet at Reynolds McCook, Illinois, plant it most likely will be rolled into foil in Richmond, Virginia, and Louisville, Kentucky.
