A tool might be made of an alloy because the alloy _____.
A. occurs naturally
B. resists rust
C. can bend easily
D. is softer
Your answer is:
B. Resists rust.
A tool might be made of an alloy because the alloy resists rust.
Why?
Iron is a great building material but steel (an alloy made by adding small amounts of non-metallic carbon to iron) is stronger, harder, and rustproof. Aluminum is a very light metal but it's also very soft in its pure form.
Alloy steels have a wide range of special properties, such as hardness, toughness, corrosion resistance, magnetizability, and ductility. Nonferrous alloys, mainly copper–nickel, bronze, and aluminum alloys, are much used in the coinage.
