A tool might be made of an alloy because the alloy _____.


A. occurs naturally

B. resists rust

C. can bend easily

D. is softer

Answers

I assume the answer is: A
~Hello Wonderful Person~

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.
