Origin of aluminumModern Latin from Classical Latin alumen: see alumina
a silvery, lightweight, easily worked, metallic chemical element that resists corrosion and is found abundantly, but only in combination: symbol, Al; at. no. 13
of, containing, or made of aluminum
A silvery-white, ductile metallic element, the most abundant in the earth's crust but found only in combination, chiefly in bauxite. Having good conductive and thermal properties, it is used to form many hard, light, corrosion-resistant alloys. Atomic number 13; atomic weight 26.9815; melting point 660.32°C; boiling point 2,519°C; specific gravity 2.70; valence 3. See Periodic Table.
Origin of aluminumalumin(a) -(i)um
Named in 1812 by British chemist Sir Humphry Davy who discovered it, after the earlier 1807 New Latin form alumium.
- Though aluminum cookware is some of the least expensive you can buy and therefore easiest on the budget of a college student or young professional just getting out on their own, if it's at all possible to skip aluminum pots and pans, do so.
- Aluminum bats are more popular these days because of the fact that aluminum is more elastic than wood-this means that when the ball hits the bat, it retains more of its kinetic energy (i.e. it will go farther outward into the field).
- Newer brick homes, like those built in the 70s or 80s, feature aluminum window frames which may have discolored or warped or the panes are finally losing their seals, which ultimately results in higher heating and cooling costs.
- A cell phone cover, on the other hand, is typically made of a hard material -- like aluminum or, more commonly, clear plastic -- that can also protect your handset from having its screen or other important components cracked.
- If you're looking for extra seating or just a seat you can carry with you to all of the outdoor events that happen in the spring and summer, consider a folding aluminum lawn chair frame with webbing for the seat and the back.
