Alloys that are composed mostly of aluminum have been very important in aerospace manufacturing since the introduction of metal skinned aircraft.
in aerospace manufacturing since the introduction of metal skinned aircraft. Aluminum-magnesium
alloys are both lighter than other aluminum alloys and much less flammable than
alloys that contain a very high percentage of magnesium.
