6K Additive & Freemelt Partner On Refractory Metal 3D Printing Powders

6K Additive is a division of 6K Inc. and a global leader in the production of sustainable advanced materials for additive manufacturing. Recently, the company announced the commercial availability of refractory AM metal powders including tungsten, rhenium, and niobium-based powders. These are used in fields such as defence, aerospace and medical industries because of their high-temperature resistance and high-strength applications. Now 6K Additive has entered a strategic partnered with high-tech Swedish firm Freemelt in order to leverage the company’s Electron Beam Powder Bed Fusion (E-PBF) printer platform that enables advanced additive manufacturing applications.

In this partnership, 6K Additive brings the production expertise and ability to produce refractory performance powders at scale, whereas Freemelt’s printing solutions can meet the high-performance demands of manufacturing sectors like hypersonic and medical. Dr. Ulric Ljungblad, CEO of Freemelt stated, “The market is consistently asking us for performance materials and partnering with 6K Additive gives us and our customers a material supplier that not only delivers high-quality metal powder but is quickly commercializing the sought-after performance materials like tungsten and other refractory metals.”

Refractory Metal AM Powders

With their melting points above 2000 °C, refractory metals are a scientific classification of metals. Characteristically, these metals hold exceptional resistance to heat and deformation. The five elements traditionally defined as refractory metals are niobium, molybdenum, tantalum, rhenium, and tungsten. Also, these metals are chemically inert and have a relatively high density. Additive manufacturing materials such as tungsten, rhenium, and niobium-based powders used in the defense, aerospace, and medical sectors are sought after for these materials’ high-temperature, high-strength applications.
