1.鋁可以部分代替鐵的領域主要是汽車外殼與輪轂，航空航天，部分建材，列車車廂(主要是高鐵車廂)，一些硬質合金，當然還有別的領域，共同點既要要求強度，同時還要要求輕量化，耐腐蝕，而后面這些要求金屬鐵做不到(部分產品需要使用鎂或鋅)

1. The main areas in which aluminum can partially replace iron are automotive casings and wheels, aerospace, some building materials, train carriages (mainly high-speed rail carriages), some hard alloys, and of course, there are other fields that require both strength and lightweight, corrosion resistance, which cannot be achieved by metal iron (some products require the use of magnesium or zinc)

　　2.鋁可以部分代替銅的領域主要是涉及輸電線路和電路當中，原因與銅的密度過大有關。但導電性能還可以接受，如果鋁的導電能力能達到銅的90%，銅有可能在絕大部分線路和電路上看不到身影，銀更不可能看到，直接在關鍵部分直接用銅即可。

The field where aluminum can partially replace copper mainly involves transmission lines and circuits, due to the high density of copper. But the conductivity is still acceptable. If the conductivity of aluminum can reach 90% of that of copper, copper may not be visible in most circuits and circuits, let alone silver. Copper can be directly used in key parts.

　　3.鋁還有一些領域是很多金屬無法勝任的，主要是用于制作切割材料，剛玉主要用于切割加工領域，可以切部分比較堅硬的金屬，只有少數幾種無法切割加工，原因是比較廢，也可以用于制作耐火材料，發揮作用的是鋁的氧化物剛玉，這種氧化物不溶于酸堿，而且還耐高溫。

3. Aluminum also has some fields that many metals cannot handle, mainly used for making cutting materials. Corundum is mainly used for cutting and processing, and can cut some relatively hard metals. Only a few types cannot be cut and processed because they are relatively waste. It can also be used to make fire-resistant materials, and aluminum oxide corundum plays a role. This oxide is insoluble in acid and alkali, and also resistant to high temperatures.
