what is aircraft grade aluminum?
Aluminum is never used in it's pure form. It is always used as an alloy - in combination with other metals and substances. The phrase aircraft grade aluminum is a bit misleading because there are a large number of different grades of aluminum used on aircraft - some of them aren't very special at all, but some of the grades are highly specialized, down to the micro-structure of the metal. Different grades of aluminum contain different quantities of other substances may have been forged or wrought in different types of processes. Typically high performance military aircraft will utilize very grade materials. The common characteristics of high grade aluminum alloys are it's ability to withstand heat and fracturing they are also extremely light. When people advertise products like keys made from aircraft grade aluminum it makes me laugh - because it's most likely to be the same grade aluminum they use to make tray stands, certainly not the same grade they use for structural components! Hope this helps!
Aircraft grade Aluminum is made to be very durable and strong, also Aluminum does not rust.
