What is the difference between pure Molybdenum and TZM alloy?

Pure Molybdenum is valued for its high-temperature stability, machinability, and cost efficiency.

TZM (Titanium–Zirconium–Molybdenum) is a Molybdenum alloy engineered to provide higher strength, improved creep resistance, and better recrystallization behavior at elevated temperatures, allowing for higher service loads and longer component life.
