Alloys are harder and stronger than pure metals. I saw this sentence,

"Alloys make the metal harder by preventing the layers of atoms from sliding."

I think it is more correct to add the word "easily" at the end of the sentence since in an alloy, it is more difficult for the layers of atoms to slide over each other.

What do you think?

    I think your sentence makes more sense than the original. I wonder a little about the use of the term harder. Does alloying always make the material harder?
