TZM Alloy Round Bar

TZM is commonly used in rocket nozzles, vacuum furnace components, die inserts, heat shields, jet engine exhaust cones, fuel cells, anodes in X-ray tubes, gas pipelines, annealing and sintering, light-alloy casting molds and high-temperature structural parts. TZM is useful where demanding mechanical load at temperatures above 900 degrees Celsius, or when recrystallization and embrittlement of pure molybdenum is a concern due to repeated temperature cycling and handling.

TZM is known for its good thermal conductivity, low expansion coefficient, high recrystallization temperature, low evaporation pressure, good corrosion resistance, and easy processing. TZM is widely used in aviation, aerospace and other fields, such as nozzle materials, trachea materials, electronic tube materials, etc.

TZM can also be applied to cathode elements of semiconductor targets, medical targets, and x-ray targets. TZM can be used to produce high temperature furnaces, heating elements, heat shields and light alloy castings. There are two production methods of TZM alloy: smelting and powder metallurgy. In industry, the earliest molybdenum alloys are titanium, zirconium and molybdenum alloys.

Plasticity and cutting performance: TZM alloy round bar has good plasticity and can be processed by heating and plastic deformation, such as forging, stretching, etc. At the same time, it has good cutting performance under appropriate processing conditions.
Welding and grinding: The alloy has good welding performance and can be connected using common welding methods. Under appropriate grinding conditions, a high-precision surface can be obtained.

Raw material selection: The main components of TZM alloy round bars include molybdenum (Mo), titanium (Ti), zirconium (Zr) and a small amount of carbon (C). The precise ratio of these elements ensures the high performance of the alloy.
Processing technology: It is prepared by arc melting-casting method or powder metallurgy technology. Powder metallurgy can simplify the process, reduce costs, and improve the yield rate.

Excellent high-temperature performance: TZM alloy has a high melting point of 2623°C, and its recrystallization temperature is 1400°C, which is much higher than that of pure molybdenum (900-1100°C). At high temperatures, TZM alloy has much better creep resistance and strength than pure molybdenum. For example, at 1400°C, its tensile strength is about twice that of pure molybdenum.

Good mechanical properties: TZM alloy has high tensile strength (760 MPa at room temperature) and hardness (220 DPH/RC). Even at high temperatures, it keeps high strength and toughness.

High thermal stability: TZM alloy has a low thermal expansion coefficient (5.2×10⁻⁶/°C) and good thermal conductivity (126 W/mK). Because of this, it resists warping and cracking under high heat.

Strong corrosion resistance: TZM alloy performs well in many chemical environments, making it suitable for industries like chemical processing, oil, and gas.

Machinability: Although TZM alloy is quite hard, it can still be shaped by machining.

Aerospace Industry: Used to make high-temperature parts like rocket nozzles, engine combustion chambers, and heat exchangers.

High-Temperature Furnace Components: Suitable for heating elements, heat shields, and support structures in vacuum furnaces.

Automotive and Machinery Manufacturing: Used to produce high-temperature molds, forging dies, and hot-forming tools.

Electronics and Semiconductor Industry: Used in X-ray tube anodes and parts for semiconductor PVD (Physical Vapor Deposition) equipment.

Nuclear Industry: Used in control rod drive mechanisms and fuel cladding for nuclear reactors.

Other High-Temperature Structural Parts: Includes supports, fixtures, and carriers for heat treatment equipment.

Purity and impurity control: Strictly control the impurity content, such as oxygen (O), nitrogen (N), silicon (Si), etc., to ensure the purity and performance of the alloy.
Performance testing: Mechanical, thermal and electrical properties of the finished product are tested to ensure that it meets the standards.
