Additive 6K announced the commercial launch of new refractory metal powders for additive manufacturing.
The company, which has developed technology capable of turning virtually any scrap metal into materials for 3D printing, says the demand for materials such as tungsten, rhenium, tungsten / rhenium and powders made from niobium is high in industries such as defense, aerospace and medical. where high temperature and high strength properties are required.
Frank Roberts, President of 6K Additive, commented: “Leading defense organizations are not just looking for refractory materials like tungsten and rhenium, they are looking for them at the production scale. The uniqueness of the UniMelt 6K microwave plasma process, combined with the expertise of our operations team, has enabled us to manufacture production scale volumes for many refractory powders such as tungsten and tungsten. /rhenium. We have spheroidized the entire spectrum of refractory powders, including tantalum, niobium and molybdenum, and we are ready to help organizations advance their applications with these materials.
Quadrus Corporation, based in Huntsville, AL, recently worked with the 6K additive to fabricate spherical tungsten rhenium for the production of a non-eroding throat insert for a powder rocket engine nozzle. Joe Sims, director of the Quadrus Advanced Manufacturing division, said the material has performed “exceptionally well” in his selective laser melting machines.
6K’s UniMelt technology is the world’s only production scale microwave plasma system and currently used to produce Ti6Al4V (grade 5 and grade 23), SS316L and nickel superalloys Ni718 and Ni625 for manufacturing additive. Last year, the company completed construction of a state-of-the-art 45,000 square foot powder production facility in Burgettstown, Pa., Which currently houses two UniMelt systems, with two more to be installed later. This year. 6K plans to expand the facility over the next year to make room for six additional systems.
