Whatever your end use, Edgtech’s niobium plates are manufactured to high standards, including ensuring the material’s metallurgy meets your specific requirements and application.

Niobium Square Plate

We can meet all common industry standards for niobium plates, such as ASTM B393 R04210 or the more stringent ASTM B393 R04200 reactor grade specification. We can also adjust the manufacturing process to tweak certain mechanical properties, grain size, and even chemistry. For example, our typical sputtering target grade niobium limits the metal to 500ppm, excluding tantalum.

Our plates are cold rolled and vacuum annealed with a proprietary reduction ratio to ensure ideal metallurgy. Each niobium plate is rigorously inspected for dimensions, surface finish, and flatness.

Whether you’re building storage tanks at a chemical plant, coating glass for camera lenses, or building a supercollider, we have the right niobium plate for you.
