To the ancients, all metal was in some ways "magical". Very few knew how to make it, and it was usually for weapons,not tools!
The first metal knives (and swords) were made from copper.But just think of what metal is.
A lump of rock is heated until it becomes a liquid.When the liquid cools it can then be "beaten" into a blade. Is that not magical?
It would certainly seem so to people without the "knowledge".
Even in modern times it is often thought that a Blacksmith makes horse shoes. Not so; that's a Farrier!
Does metal itself have any magic power? Well, like all Matter, it vibrates, and so has "energy".
So, yes, there can be "magic" in metals.
