TZM Alloy

TZM alloy is a high-temperature alloy composed primarily of titanium (Ti), zirconium (Zr), and molybdenum (Mo). The acronym “TZM” comes from the initials of the main alloying elements. This alloy exhibits excellent mechanical properties and high-temperature performance, making it suitable for a wide range of applications in demanding environments. Here are some key features and applications of TZM alloy:


  1. High Melting Point: TZM alloy has a high melting point of approximately 2,623 degrees Celsius (4,753 degrees Fahrenheit), which allows it to withstand extreme temperatures without significant deformation.
  2. High Strength: TZM alloy demonstrates high strength at elevated temperatures, making it suitable for applications requiring excellent mechanical performance in demanding environments.
  3. Good Thermal Stability: This alloy maintains its mechanical properties at elevated temperatures, providing good resistance to thermal stress and deformation.
  4. Low Thermal Expansion: TZM alloy has a low coefficient of thermal expansion, which means it exhibits minimal dimensional changes with temperature fluctuations.
  5. Good Corrosion Resistance: TZM alloy offers good resistance to corrosion and oxidation, enhancing its suitability for applications in aggressive environments.


  1. Aerospace and Defense: TZM alloy is utilized in aerospace and defense industries for applications such as rocket nozzles, combustion chambers, and reentry vehicle components, where high-temperature performance and strength are crucial.
  2. Furnace and Heat Treatment: TZM alloy is used in high-temperature furnaces and heat treatment equipment, including heating elements, crucibles, and fixtures, due to its excellent thermal stability and resistance to deformation at elevated temperatures.
  3. Medical and Industrial Radiation Shields: TZM alloy is employed in radiation shielding applications, such as medical radiation therapy equipment and industrial facilities that handle radioactive materials, owing to its high density and radiation absorption properties.
  4. Glass and Ceramic Industry: TZM alloy is used in glass melting and ceramic production processes due to its ability to withstand high temperatures and resist chemical attack from molten materials.
  5. Electronics and Semiconductor Manufacturing: TZM alloy finds application in the electronics and semiconductor industry, where it is used for components that require high-temperature strength, such as sputtering targets, crucibles, and thermal evaporation boats.

TZM alloy offers a combination of strength, high-temperature stability, and corrosion resistance, making it a valuable material for applications in aerospace, defense, heat treatment, radiation shielding, and various other industries that require reliable performance under extreme conditions.
