6K Additive is a US-based manufacturer of premium metal powders and alloy additions made from sustainable sources. Headquartered in Burgettstown, PA, our manufacturing process allows us to produce powders that are truly spherical, void of porosity and satellites with better flowability than competing technologies. We utilize our innovative UniMelt® microwave plasma process, where we leverage domestically sourced feedstock such as certified millings from CNC, grindings, used additive powder or even the support material used in AM. Our premium powder offerings include, Nickel 718, Nickel 625, Titanium 64, SS316L, Copper 18150, and refractory powders that include, Tungsten, Rhenium, Niobium C103 and Tungsten-Rhenium to name a few. 
6K Additive is also a recipient of a $23.4M DPA Title III grant where the company will be taking components from the military depots and turning critical material such as titanium and nickel back into powder and pre-ingots to be used for military applications.
