TZM Alloy

TZM alloy, or titanium-zirconium-molybdenum alloy, is a high-performance material that is becoming increasingly popular in a variety of industries. This molybdenum-based alloy offers a unique combination of strength, toughness, and high-temperature resistance that makes it well-suited for use in demanding applications.

Properties of TZM Alloy

TZM alloy is made by adding small amounts of titanium and zirconium to pure molybdenum. The addition of these elements improves the properties of molybdenum, making TZM alloy a high-performance material with excellent strength and toughness.

TZM alloy has a higher recrystallization temperature than pure molybdenum, making it more resistant to thermal creep and deformation at high temperatures. Additionally, TZM alloy has a higher ultimate tensile strength and a higher modulus of elasticity, making it stronger and more rigid than pure molybdenum.

Applications of TZM Alloy

TZM alloy is used in a variety of applications due to its unique combination of properties. Some of the most common applications of TZM alloy include:

  • Aerospace: TZM alloy is used in the aerospace industry for high-temperature components, such as nozzle shrouds, combustion chambers, and heat exchangers.
  • Nuclear: TZM alloy is used in nuclear applications for components that require high-temperature resistance and strength, such as control rod drives and fuel cladding.
  • High-temperature furnace components: TZM alloy is used for furnace components, such as heating elements and insulation supports, due to its high-temperature resistance and strength.
  • Medical devices: TZM alloy is used in medical devices, such as dental implants and surgical instruments, due to its biocompatibility and high strength.

These are just a few of the many applications of TZM alloy. As this high-performance material continues to gain popularity, it is likely that new applications will emerge in the future.
