Enriched Iron can be used in creating Steel or a Heat Generator . It is created by using 2 Enriched Alloys and 1 Iron. Enriched Iron can be used in the creation of Steel when put into a Metallurgic Infuser. The Enriched Iron needs to be infused with Compressed Carbon to operate, at the rate of 1 compressed carbon for every 10 enriched iron.
Once you have an Enrichment Chamber you can process Copper Ore with it to make Copper Dust, which can be used in place of the Enriched Alloy in this crafting resulting a huge savings on redstone.
