Some fun information about

Aluminum and why you will

continue to see an increase in

Aluminum products for our

industry.

Aluminum derives its name

from alum. The Latin name

for alum is ‚alumen‘ meaning

bitter salt.

Aluminum is the 3rd most

abundant element in the

Earth‘s crust.

Before the discovery of the

Bayer and Hall–Héroult

processes, aluminum was

more expensive than gold or

silver. Napoleon III served state

dinners on aluminum plates.

Aluminum helped pioneer

flight. The Wright brothers

used aluminum to build key

parts of their biplane’s engine

because no manufacturer

could provide an engine light

enough with the needed

horsepower.

The lifespan of an aluminum

can is recycled over and over

again in a true closed loop.

Unopened aluminum cans

are very strong, despite being

so thin. Four six-packs of

cans are able to support the

weight of a 2-ton vehicle!

Recycling efforts can be im-

proved every three months,

Americans throw away enough

scrap aluminum to rebuild the

entire U.S. commercial airplane

fleet.

Recycling that metal would

save the energy equivalent of

16 million barrels of oil!

Aluminum is 100 percent

recyclable and retains its

properties indefinitely.

Aluminum is one of the only

materials in the consumer

disposal stream that more

than pays for the cost of its

own collection.

The top three countries that

mine aluminum are are

Guinea, Australia and Vietnam.

Australia, China and Brazil

lead the world in aluminum

production.

Aluminum Uses then and now

Ancient Greeks and Romans

used alum as an astringent,

for medicinal purposes, and as

a mordant in dyeing. It is used

in kitchen utensils, exterior

decorations, and thousands of

industrial applications.

The alloys of aluminum are

used in the construction of

aircraft and rockets.

It’s also used in fireworks to

produce sparks and white

flames.

Aluminum is a common

component of sparklers.
