525Ferroalloys By Norman A'~ Mauhews1 The overall structure of the domestic ferroalloy industry did not change basically during 1972. Management elected to close some older plants rather than invest heavily in the pollution control equipment necessary to meet the stringent emission requirements projected for 1976. The volume of business improved at yearend as the principal consumers of ferroalloys, the steel, cast iron, and aluminum industries, approached capacity operations. However ferroalloy imports increased to such a degree that total domestic shipments remained practically unchanged compared to those of 1971. Exports of ferroalloys con- tinued to decline with the total volume reduced 43,000 tons (49%), whereas value declined only $3 million as the export product mix changed considerably. Published prices were generally constant during the year but did not govern in many of the major commodities as domestic producers acted to counter prices of imported products. Detailed information concerning utilization of individual elements in various alloy products may be found in the chromium, manganese, silicon, molybdenum, nickel, tungsten, and vanadium chapters. 1 Physical scientist, Division of Ferrous Metals.
