Compared to molybdenum, TZM has a higher recrystallization temperature and higher heat resistance. It is therefore a material which is perfectly suitable for producing tools which must have a particularly high heat resistance. The use of TZM is preferable to molybdenum for the assembled parts because it is better suited for welding.
