What caused the aluminum price to rise?

There are two main reasons for the rise in aluminum prices:

First, global aluminum demand is active, and aluminum stocks continue to decline. Since March, domestic aluminum stocks have basically declined week by week, and inventory factors support aluminum prices.

Second, the downstream industries in China and even in the world are recovering strongly, and the infrastructure at home and abroad is expected in the future. The strong performance of the automobile industry has also formed obvious support for aluminum prices.

Content distribution

The most abundant metal element in the crust is 8.3%. It mainly exists in aluminosilicate ores, as well as bauxite and cryolite. Alumina is a white amorphous powder with many variants, among which α-Al2O3 and β-Al2O3 are the most common.

The corundum existing in nature belongs to α-Al2O3, which is second only to diamond in hardness, high melting point and acid and alkali resistance. It is usually used to make some bearings, abrasives and refractories. Such as corundum crucible, can withstand the high temperature of 1800℃. Al2O3 has many colors because it contains different impurities. For example, a trace of Cr(III) is red, which is called ruby; Sapphire containing Fe(II), Fe(III) or Ti(IV) is called sapphire.

Aluminum is a light metal with chemical symbol Al and atomic number 13. The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third. It is the most abundant metal element in the earth's crust, and its reserves rank second among metals. Among the metal varieties, it is the second largest metal after steel.
