There are many different answers but some of the most common ones are:
- Aluminium is very expensive when being extracted
- Aluminium on it's own is a soft metal, but it makes hard alloys. these can be used for planes, electricity cables, window frames, etc.

Why is pure aluminium oxide mixed with cryolite before electrolysis?
to lower its melting point as the process is very expensive :)
What is golds hardness?
Gold on the selves is actually an amalgam ( mixture of several metals) so it is mixed with aluminium, iron etc. In theory pure gold is malleable
What is an aluminium gallium arsenide?
In inorganic chemistry, an aluminium gallium arsenide is a mixed arsenide of aluminium and gallium, used as a semiconductor.
Why are metals usually more useful when they are mixed?
Tin, copper, lead. (So Bronze, solder, brass.)
Why are metals found underground?
Not all metals are found underground- a few can be found at the surface. However, metals are usually not fund in a pure form, but are mixed with impurities in the form of ore, which was distributed vertically and horizontally as that rock strata was formed.
Can aluminum be combined with metal?
Yes. There are several alloys where aluminium is mixed with other metals.

Are semi-metals the same as mixed metals?
They are usually called metalloids. They are in the middle of being a metal and a non-metal

Does aluminium contain lead?
mixed yes, melted together and cooled, or even just mixing up bits of metal. they will not bond together, 2 metals almost never can

What is the industrial name for Aluminium mixed with magnesium and copper?
"heat treatable aluminum alloy". There are usually other elements added as well, for various properties.
What is magnesium mixed with aluminum?
Magnalium is an alloy magnesium-aluminium.
Why are aluminum alloys used instead of aluminum itself?
by itself aluminum is soft and not very strong but when mixed with the right other metals it can become stronger than either were alone
What do metals include?
alkaline metals, alkaline earth metals, lanthanides and actinides and metals in mixed groups
