More realistic metals

So I've heard that mojang will be adding copper a new metal into the game. So I have the idea of making minecraft metals more "realistic" so here is my idea iron armour should be more protective than copper armour and their tools are more efficient as well but if you don't wax your armour and tools it will slowly rust and lose its efficiency and durability but on the other hand copper tools and armour provide more durability but less efficiency like for example an iron Sword does 5 dmg while a copper sword does 4 dmg but the iron Sword (if not waxed) will slowly rust and if the oxidation is complete then the iron Sword will just deal 3 dmg and the durability will suck but if you let your copper tools oxidize then its durability will increase by just a bit and since copper can conduct electricity easily. I think there should be a new enchantment for only copper Swords that new enchantment is none other than Electro shock I&II this new enchantment has a chance of electrifying the target (I is around 15% and II is around 25%) dealing more damage and stunning the target for 1-2 seconds and maybe there could be new enchantments for copper armour to like Electric thorns or something like that anyways that is my idea I know it's kinda long but hey some ideas are just long... anyways that is it and I hope you find this idea interesting
