Porous metal CELMET™
- Celmet™ consists of a porous metal body with triangular-prism shaped cells to form a 3D structure.
- The available materials include not only pure nickel (Ni) but also nickel-based alloys, such as nickel-chromium (Ni-Cr) and nickel-tin (Ni-Sn). These materials are produced in the world’s largest-scale production plant.
