Freemelt welcomed Fusion for Energy delegation for joint tungsten project
The F4E delegation was given insights into Freemelt’s production capabilities and met with key team members.
The project aims to qualify tungsten for fusion energy applications and accelerate innovation in the field. Together with Fraunhofer IGCV, Freemelt is developing advanced methods for joining tungsten and the copper alloy CuCrZr, critical materials for handling extreme heat in fusion reactors.
Tungsten for fusion energy
Stefan Wikman, Head of Materials, Manufacturing and Metrology at F4E: “We had fruitful discussions with Freemelt regarding the ongoing project to develop tungsten as a Plasma Facing Material, a critical technology area for fusion reactor development. Freemelt already has the capability to manufacture tungsten for ITER relevant operational conditions and is well positioned to develop critical materials for future power plants.”
Per Woxenius, Senior Advisor, Responsible Energy at Freemelt: “We are delighted to partner with F4E in advancing fusion as a commercial energy source. Using our E‑PBF (Electron Beam Powder Bed Fusion) technology to manufacture tungsten components for future fusion systems marks a significant step for Freemelt in the energy sector.”
Important project for Sweden
“This is a strategically important project not only for Europe’s fusion programme, but also for Sweden,” said Max Collins at Big Science Sweden and Industrial Liaison Officer (ILO) for Fusion for Energy. “Freemelt’s additive manufacturing expertise strengthens Sweden’s position in the fusion supply chain and opens up new possibilities for how we design and manufacture heat-resistant components for future reactors.”
