USE OF WELDED ALUMINUM ALLOY STRUCTURES IN THE TRANSPORTATION FIELD

IMPIEGO DELLE STRUTTURE SALDATE DI LEGA DI ALLUMINIO NEI TRASPORTI

A comparison between steel (non alloyed, Fe 42 grade) and aluminum (AlZnMg 1, AlMgSi 1 and AlMg 2.5) seen from the designer's standpoint, 5 points are considered: unit cost of material, amount of material required to provide the same structural properties, labor, dependability in use, advantages of light alloys. The first item is not encouraging in Italy: light alloys are 5 to 8 times more expensive than steel. However, the aluminum alloys make it possible to reduce weight more than three times in comparison with steel, if calculated on the basis of yield point, or more than 1.5 times on the basis of U.T.S. Welded joints on aluminum require 30% more time, but large extrusions reduce the number of joints necessary for aluminum. Dependability is equal or superior to steel, and corrosion resistance is better. Running costs are markedly lower with aluminum structures.
