6K

6K Inc is a North Andover, Massachusetts advanced-materials company that produces engineered powders and battery materials with UniMelt, its patented microwave-based production-scale plasma system. Named for the roughly 6,000 K plasma temperature it operates at — the temperature of the surface of the sun — UniMelt uses tightly controlled thermal plasma beams to melt or vaporize precursor feedstock into particles with precise size distribution and crystalline phase, in seconds rather than the days conventional processes require, while cutting energy use and eliminating wastewater. The company operates through two divisions. 6K Additive, with production in Burgettstown, Pennsylvania, makes sustainably sourced metal powders for additive manufacturing — titanium Ti-6Al-4V, nickel superalloys Ni625 and Ni718, stainless SS316L, refractory tungsten, niobium C103, copper C18150 and the HEA1000 refractory alloy — reclaiming CNC scrap and revert metal into premium AM powder. 6K Energy produces domestically sourced lithium-ion battery cathode and solid-state materials including NMC, LFP, LLZO, LMO, LTO and LNMO. Additional applications span semiconductor CMP, specialty ceramics, advanced coatings, lighting and display materials, nano-engineered powders, and federal/defense programs; 6K has received US Department of Defense and Department of Energy awards for domestic critical-materials capacity. 6K is a privately held company whose shares trade on secondary markets. Enrichment probing on 2026-07-31 found no public developer API, OpenAPI/AsyncAPI/GraphQL contract, developer portal, SDK, MCP server, agent card, or event surface — 6K is a materials manufacturer, not an API provider.

6K is profiled on the APIs.io network. Tagged areas include Company, Advanced Materials, Manufacturing, Additive Manufacturing, and Metal Powders.

6K’s developer surface includes engineering blog, support, YouTube channel, and 7 more developer resources.
