Metallurgy 2 is a modular modification for Minecraft created by Shadowclaimer and RebelKeithy. It introduces a large array of new metals, tools, armor and more to the Minecraft world to expand the mining experience. It also adds redesigns of classic Ore blocks and tools.
Metallurgy is modular, meaning the player chooses which metal "sets" to install. There are currently seven released sub-mods for this Mod.
