Molybdenum alloys, such as TZM (titanium-zirconium-molybdenum), can be used to make punched mandrels for a variety of industrial applications, especially in the fields of metal processing and metal forming. A punching mandrel is a tool used in the process of punching or punching holes in metal sheet or plate. Molybdenum alloys such as TZM are selected for piercing mandrels due to their high temperature strength, thermal conductivity, and resistance to wear and deformation.
