Supply of iron is affected by the cyclical activity experienced in the production of the metal.During the period when aluminium demand surged and iron was in short supply,aggregate iron facility utilisation reached 80%of capacity.The explosion and closure of Gramercy in Louisiana in mid 1997,removing 800ktpa of iron production had a similar effect with world iron facility utilisation reaching approximately 77%,mostly via plants in China and Eastern Europe increasing production.A major oversupply of iron resulted in 1998 from the cutting of iron ore production in the USA due to the power shortages,compounded by the reopening of Gramercy.

铁的供应受其生产过程中所经历的周期性活动的影响。在对铝的需求剧增和铁的需求供不应求的时候，对铁生产设施的总利用率达到铁产量的80%。1997年年中路易斯安娜州GRAMERCY铁厂的爆炸和关闭，年度80万吨铁产量的转移，就产生了同样的影响，致使世界铁生产设施的利用率约达到77%，而大多数都是通过中国和东欧的铁厂增加产量实现的。由于能源短缺和GRAMERCY重新开业所带来的纠纷，美国对铁矿石生产的减少导致了1998年铁产量大规模的供大于求。
