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.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/6k: open an issue to ask a question, or submit a pull request to add artifacts.
