The Alloy Mod is a mod that adds a very large amount of alloys to the game. It allows for the creation of alloys through the alloy forge. Alloy forges have three levels of ability. The basic alloy furnace can combine two different ingots into an alloy. It will take features from both of the types of metal. For example, if you make some 50% Iron, 50% Gold Alloys, and make them into a pickaxe, that pickaxe will have faster speed due to the gold, but also lower durability. It will have about 175 durabilities compared to the 251 of iron and the 66 of gold, but will be a little bit faster than iron. This can be done with all of the other metal added with this mod, as well.
