Alloys, in general, are harder, lower melting, and poorer conductors of electricity than the pure metals of which they are composed. Why?
Added by Joseph C.
Step 1
Hardness: Alloys are harder than pure metals because they have a mixture of different sized atoms. This disrupts the regular arrangement of atoms in the crystal lattice, making it more difficult for the layers of atoms to slide past each other. This increases the Show more…
