Here, athe world's widest sheet and plate is rolled from the largest ingots cast anywhwere in the aluminum industry. From ingots weighing more that 7,000 pounds, aluminum coils weighing in excess of 5000 poinds are produced. Coils produced at other mills weight approxi- mately 3,000 poinds. The 100-inch continuously Hot Mill produces aluminum sheet in escess of 90 inches wide. Previously, a max- imun of 60 inches was the maxium. Aluminum is melted at 1400° and rolled at 900°.
