Domestic consumption and intensity of use trends for 12 metals, by industrial end use, were estimated for 1972 through 1982. The trends were then forecast through 1993 using standard statistical methods. The intensity of use measure selected is the quantity of metal consumed per constant dollar output of a specific industrial sector. The metals studied were aluminum, chromium, cobalt, copper, lead, manganese, nickel, the platinum-group metals, tin, titanium, tungsten, and zinc. Average annual growth rates for 4 of the 12 metals increased from 1972 to 1982 as follows: aluminum, 1.00%; Platinum-group metals (consisting of platinum, palladium, and iridium), 8.83%; Titanium, 7.82%; and tungsten, 6.09%. Consumption for the remaining eight metals decreased at annual rates ranging from 0.58% (Copper) to 5.37% (Manganese).
