The price of steel and aluminum increased.
Aluminum (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Al includes a density not up to those of alternative common metals, at close to one-third that of steel. it's an excellent affinity towards oxygen and forms a protecting layer of oxide on the surface once exposed to air. Al visually resembles silver, each in its color and in its great ability to replicate light. it's soft, non-magnetic, and ductile. it's one stable atom, 27Al; this isotope is incredibly common, creating aluminum the twelfth most typical element within the Universe.
Chemically, aluminum is a post-transition metal in the boron group; as is common for the group, aluminum forms compounds primarily in the +3 oxidation state. The aluminum cation Al3+ is little and extremely charged; as such, its polarizing, and bonds aluminum forms tend towards covalency.
