Invar Blend is produced when combining two piles of Iron Dust with a pile of Nickel Dust. This results in 3 piles of invar dust. Two piles of Iron Dust and a pile of Pulverized Ferrous Metal will also produce Invar Blend.
It can also be used to generate larger quantities of Mixed Metal Ingots (4/5 per crafting)
