Isothermal Forging Dies
Elmet Technologies specializes in engineering and manufacturing isothermal forging dies with advanced performance characteristics. Our extensive material capabilities includes the customization of alloys to improve the overall forging process, therefore resulting in higher quality end products. We offer complete control over material integrity, quality, and performance.

Materials include molybdenum alloys, such as Titanium-Zirconium-Molybdenum (TZM), and Molybdenum Hafnium Carbide (MHC). We also produce other custom materials optimized for isothermal forging conditions. Our team of expert metallurgists and engineers work closely with each customer to select materials and tailor them to specific applications, forging geometries, and requirements.

What Is Isothermal Forging?
Isothermal forging is a precision forming process performed at elevated temperatures, where both the die and workpiece are held at nearly constant temperature during deformation. This controlled environment minimizes thermal gradients, allowing for superior grain flow, tighter tolerances, and improved material properties. Isothermal forging is especially critical when metalworking with difficult-to-form materials, such as titanium, nickel-based superalloys, and refractory metals.
