What are the properties of TZM at high temperatures?
TZM is a refractory metal alloy consisting primarily of 99% molybdenum, 0.5% titanium, and 0.08% zirconium. It has excellent high temperature performance and is suitable for various applications in extreme high temperature environments. Some properties of TZM at high temperatures include:
High melting point: TZM has a high melting point of approximately 2,623°C (4,753°F), allowing it to withstand extreme temperatures without major structural changes.
Mechanical Strength: Unlike pure molybdenum, TZM retains its mechanical strength and does not undergo significant softening at elevated temperatures. This makes it suitable for high stress applications.
Thermal conductivity: TZM has good thermal conductivity, allowing it to effectively conduct heat away from the material and reduce the risk of overheating in high temperature environments.
Low Thermal Expansion: TZM has a relatively low coefficient of thermal expansion, which means it expands and contracts less with temperature changes than other materials. This property helps minimize dimensional changes and maintain stability even at high temperatures.
High Creep Resistance: Creep refers to the deformation of materials under long-term exposure to high temperatures and constant stress. TZM has excellent creep resistance, making it suitable for applications that are subject to high temperatures for long periods of time.
Corrosion Resistance: TZM is highly resistant to corrosion, even in corrosive environments such as molten metals and strong acids. This property makes it suitable for applications where corrosion resistance is critical.
Overall, the combination of high melting point, mechanical strength, thermal conductivity, low thermal expansion, creep resistance, and corrosion resistance make TZM a reliable material for high-temperature applications such as aerospace, defense, nuclear energy, and high-temperature furnaces.
