Diffusion Bonding Dies
Elmet Technologies manufactures precision diffusion bonding dies to meet the exacting specifications of high-performance applications. Built from molybdenum alloys such as TZM and MHC, our dies maintain structural integrity under extreme thermal and mechanical stress, ensuring consistency and high-quality materials across complex geometries. All dies are custom fabricated to support uniform heat distribution and precise pressure control, maximizing performance and integrity during the bonding cycle.

Our team of experts is here to help develop custom components and design alloy materials to meet unique performance needs. Through our unique and expanding capabilities, Elmet Technologies sets a new standard of forged products for the aerospace and defense industries. We manufacture a wide range of large sizes in several shapes and geometries. Additionally, we offer finite element modeling (FEM) and extensive powder metallurgy capabilities to ensure diffusion bonding dies fulfill market requirements.

What Is the Diffusion Bonding process?
Diffusion bonding is a solid-state welding technique where two or more metal surfaces are fused together through the application of controlled heat and pressure over time. The technique of diffusion bonding enables the formation of high-strength joints, particularly between metals that are difficult to weld using conventional methods. In diffusion bonding, the role of the die is critical. At Elmet Technologies, we understand how design, material selection, and surface finish of the die directly influence the bond quality, dimensional accuracy, and structural integrity of the final assembly.
