铝在地壳中的储量为8%左右,是储量位于第三的元素,生产铝的矿产资源丰富,全球储量还可持续开采200年。从铝土矿开采到生产氧化铝,再到生产原铝成本巨大。一方面随着能源成本的增加和全球对铝需求的持续增长,铝价将持续上涨;另一方面铝的可回收性很强,铝型材挤压工业的废料可以直接加工成挤压坯料,加工成本仅为原铝的10%,能源消耗仅为原铝的5%。 Aluminum reserves of about 8% in the crust, is the reserves in the third element, the production of aluminum is rich in mineral resources, global reserves can continue mining 200 years. From the bauxite mining to the production of alumina, and then to the production of primary aluminum, the cost is huge. On the one hand, as the cost of energy increases and the global demand for aluminum continues to grow, the price of aluminum will continue to rise. On the other hand, the recyclability of aluminum is very strong. The scrap from the aluminum extrusion industry can be directly processed into extruded billets and processed The cost is only 10% of primary aluminum, energy consumption is only 5% of primary aluminum.
