Manufacturing Process of Tantalum Sheet & Plate

High-purity tantalum powder is sourced and prepared for processing, ensuring the best starting material for the production of tantalum sheet & plate.

The tantalum powder is melted in a controlled vacuum environment using an electron beam furnace, ensuring a pure and high-quality melt.

If necessary, specific alloys are mixed with tantalum powder to achieve desired material properties. The powder is then processed to form a uniform mixture.

The molten tantalum is forged into initial shapes through mechanical processes, forming billets that will be further processed into sheets and plates.

The forged billets are hot-rolled or cold-rolled into sheets and plates of the desired thickness, refining the material's structure and ensuring the required dimensions.

The rolled tantalum sheets and plates undergo heat treatment to improve their mechanical properties, followed by precise cutting to meet customer specifications.
