Tungsten

I think Tungsten should be in Minecraft. Its tools and armor should be intermediate between iron and diamond gear, and its durability should be nearly as good as diamond. To make it worth crafting, It should have the added ability of having an improved chance of getting a high level of fire protection when enchanted(tungsten is extremely heat resistant in real life). the Tungsten sword could even have a higher chance of getting fire aspect. To balance this out, I feel as though Tungsten ore should only be smelt-able through the use of a blast furnace(taking a more realistic approach). Tungsten should have a rarity similar to gold, and could only be found around as deep.
