Copper iron alloy

So when the caves and cliffs update was announced it got me thinking on what you could do with some of the new features, I went looking online and found out that a iron copper alloy is actually a great electricity conductor so it could be added in as a way to make a more powerful repeater or other items like that it would be crafted using 2 iron ingots and 2 copper ingots and then could be used in a recipe from there. This is just a suggestion but I think it would be cool to have an alloy of some type in the game.
