TZM Molybdenum Alloy Description

TZM alloy, also called TZM molybdenum alloy, refers to the Titanium-Zirconium-Molybdenum alloy. TZM Alloy contains 0.50% Titanium, 0.08% Zirconium and 0.02% Carbon. TZM Molybdenum Alloy is manufactured by either P/M or Arc Cast technologies. TZM Alloy has higher creep resistance and strength than pure molybdenum. SAM produces a wide range of molybdenum and molybdenum alloy mill products including forging billets, bars, rods, sheets, plates, and foil.

Molybdenum (Mo) is gray-metallic and has the third-highest melting point of any element next to tungsten and tantalum. It is found in various oxidation states in minerals but does not occur naturally as a free metal.

Molybdenum is well-known for its strength and stability in high-heat applications. It is often alloyed with other compounds to improve corrosion resistance and strength at high temperatures. Consequently, molybdenum is frequently used for making steel alloys, high-strength alloys, and superalloys. Molybdenum compounds usually have a low solubility in water. Industrially, they are used in high-pressure and high-temperature applications such as pigments and catalysts.

FAQs

Q1. What are the differences between TZM Alloy and Pure Molybdenum?

Composition: Pure molybdenum consists of 99.95% Mo, while TZM alloy contains 0.5% titanium (Ti) and 0.1% zirconium (Zr), which improves its properties.

High-Temperature Strength: TZM retains higher strength at elevated temperatures compared to pure molybdenum.

Creep Resistance: TZM has superior creep resistance, making it ideal for load-bearing applications at high temperatures.

Recrystallization Temperature: TZM has a higher recrystallization temperature (around 1,100°C) than pure molybdenum (~900°C), enhancing its performance in extreme environments.

Q2. What is the working temperature of TZM Allolys?

TZM alloys are suitable for working temperatures between 700°C and 1,400°C.

Like pure molybdenum, TZM begins to oxidize at around 400°C and experiences rapid oxidation above 500°C in an oxidizing atmosphere.
At room temperature, TZM has similar strength to pure molybdenum.
Above the recrystallization temperature of pure molybdenum (900–1,100°C), TZM maintains significantly higher strength.
In load-bearing applications above 1,300°C, TZM is twice as strong as pure molybdenum.

Q3. What are the main applications of TZM Alloy?

Aerospace & Defense: Rocket nozzles, heat shields, and high-temperature structural components.

Industrial Furnaces: Hot zone components, crucibles, and heat-resistant shielding.

Electronics & Semiconductors: Heat sinks and electrical contacts in high-power devices.

Nuclear & Energy Sector: Components for nuclear reactors and high-temperature energy systems.
