Over the past 10 years, the development of aluminum products has been closely linked to changes in demand across various sectors. Table 1 shows the shift in demand for aluminum products by application from 1961 to 1970, with construction and infrastructure showing significant growth in both share and growth rate. The construction sector saw a notable increase in the proportion of aluminum products, followed by transportation, power, and food industries. Other sectors, such as daily goods and electrical communication, experienced a decline in their share. The growth rate of aluminum products was highest in the construction and food sectors, with transportation and infrastructure also contributing significantly to the overall growth rate of 18.3%. This indicates that the construction sector was in a rapid growth phase, while transportation and infrastructure were in a stable growth phase. In contrast, daily goods and electrical communication sectors had declining shares and lower growth rates, suggesting they had passed the peak of their lifecycle. Table 3 shows the number of aluminum products introduced from foreign technologies by sector, with construction and infrastructure being the largest. Table 4 shows the number of new aluminum products developed by year and sector, with construction and infrastructure again leading. These data suggest that the development of new technologies and products is closely related to the changes in demand across different sectors. From 1961 to 1970, major developments in aluminum products included the construction of the first fully aluminum alloy bridge in Japan, the use of aluminum in shipbuilding, and the development of new aluminum products in various sectors such as construction, transportation, and electrical engineering. The development of aluminum products was closely linked to the needs of different industries, and the use of aluminum in various applications continued to expand. The report highlights the significant progress in the development of aluminum products during this period, with many new products being introduced and the application of aluminum in various fields expanding.Over the past 10 years, the development of aluminum products has been closely linked to changes in demand across various sectors.
