Alloy just means a combination of elements. There are many alloys of aluminum, steel, titanium, etc.
The barrel is apparently an aluminum alloy of some sort….so it’s not very hard in comparison to steel.
An electroless nickel coating with Teflon will make the surface hard…but it’s only hard for maybe .001” or less most likely.
