Iron Dust is an item added by Industrial Craft 2. It's one of the six kinds of Dusts and is obtained by macerating Iron Ore, Nether Iron Ore, Iron Ingots, Refined Iron, by crafting it with Ferru, or by obtaining it from a Scrap Box. It can be turned back into an Iron Ingot by smelting it, or used in the crafting of the Invar Blend.
Iron Dust is functionally identical to Pulverized Iron.
