What can an alloy do?

Answer:
It depends on the alloy.
There are two basic reasons to make an alloy: to make a metal stronger, so you use less of it for the same strength; and to make a metal structure less expensive. Steel is an example of the first. Less-than-24-karat gold is an example of the second.
