Self-Piercing Rivets Self Awareness
Aluminum, or aluminium if you prefer, was first discovered in the early 1800’s and produced in quantity in 1824. By the turn of the century, aluminium was being reliably cast, rolled and formed. Automakers quickly discovered its attributes and it has played an important roll in automobile construction ever since.
Aluminum has been used for doors skins, hoods, trunk lids, engines, radiators, suspension components and interior trim. The weight saving and attractive appearance aluminum provides are definite benefits, but steel has been the more traditional material used in automobile body and frame construction because of low cost and easy joining methods. That is gradually changing.
