Incorrect-ish. Alloys have metallic bonds, colloquially a "sea of electrons." There are no[0] discrete, covalent bonds like you would find in nonmetallic molecules. But the atoms are absolutely bonded in the sharing electrons sense. This is what gives strength and toughness to metals.

[0] - grossly oversimplifying here. Also I was mostly an organic chemist and didn't study metallurgy much.
