The auto industry of steel aluminum sheet
Auto industry is a large consumer of steel aluminum sheet , Most consumer products from toaster ovens to computer cases begin as rolled aluminum sheet. aluminum sheet are a roll mill or cluster mill is composed of multiple rolls and is capable of reducing material to extremely thin thicknesses. The auto industry is a large consumer of steel sheet. Aluminum (Al) is an element in the boron group with atomic number 13. It is a silvery white, soft, ductile metal and is the third most abundant element (after oxygen and silicon), as well as the most abundant metal, in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminum metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. The chief ore of aluminum is bauxite. Aluminum is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of...
