6K Additive, a division of 6K Inc based in Andover, Massachusetts, USA, has received independent certification from Scientific Certification Systems (SCS) Global Services. This third-party auditing and certification organisation has confirmed that 6K Additive’s Ti-6AL-4V powder has achieved a minimum of 95% post-consumer recycled titanium content.

The SCS Recycled Content Certification assesses products made from pre-consumer or post-consumer material that has been diverted from the waste stream. This certification quantifies the percentage of recycled content to ensure accurate claims in the marketplace.

“We are thrilled that our commitment to sustainability has been recognised by a leading organisation such as SCS Global Services through their certification process. We’re seeing a big increase from customers asking for not only data, but third-party validation from their suppliers regarding sustainability and having a recognised certification from a global sustainability organisation like SCS is exactly the type of confirmation they are seeking,” shared Frank Roberts, president of 6K Additive. “Our proprietary technology for processing titanium and refractory metals at scale is a benefit to our customers and the environment by recycling scrap streams back into premium powders.”

6K Additive is a global producer of AM powder derived from sustainable sources, offering a wide range of premium powders, including nickel, titanium, copper, stainless steel, aluminium alloys, and refractory metals such as tungsten, niobium, and rhenium. The company utilises its UniMelt® microwave plasma process for large-scale production, which enables precise spheroidisation of metal powders, controls the chemistry and porosity of the final product, and ensures zero contamination with high throughput production.

Last year, 6K Additive released a study conducted by Foresight Management. This study compared the environmental impact of 6K’s UniMelt microwave plasma technology to conventional atomisation technologies used in metal powder production. The results demonstrated a 90% reduction in energy usage and carbon emissions for its nickel-based alloys, and a 75% reduction for its titanium alloys.
