6K Inc.

6K Inc. is a company focused on the sustainable production of engineered materials for advanced industries. Utilizing its proprietary UniMelt® microwave plasma technology, the company aims to revolutionize manufacturing processes by offering a cleaner, more efficient, and domestically sourced alternative to traditional methods. Headquartered in North Andover, Massachusetts, 6K's mission is to develop innovative materials that advance sectors such as additive manufacturing, renewable energy, aerospace, and consumer electronics.

The company operates through two primary divisions: 6K Additive and 6K Energy. 6K Additive specializes in producing high-performance metal powders for additive manufacturing, leveraging sustainable feedstock sources like certified millings and turnings. 6K Energy focuses on developing cathode active materials (CAM) for lithium-ion batteries, aiming to establish a localized and sustainable supply chain for battery production. The UniMelt® technology enables rapid material processing, significantly reducing energy consumption, CO2 emissions, and wastewater compared to conventional production methods.

Recent developments include an $82 million Series E funding round in September 2024 to scale up production for battery CAM and expand metal powder capabilities. The company has also secured significant government support, including a $50 million grant from the U.S. Department of Energy for its PlusCAM™ cathode material production and a $23.4 million Defense Production Act Title III grant for 6K Additive. Saurabh Ullal serves as the CEO, leading the company's strategic growth and market positioning as a key player in sustainable advanced materials.
