Cutting Methods and Forming Processes of TZM Molybdenum Alloy Plates

TZM molybdenum alloy is a material with excellent mechanical properties and high-temperature resistance, widely used in aerospace, nuclear industry, and high-temperature furnace applications. Due to its high hardness, high melting point, and low ductility, the cutting and forming processes of TZM molybdenum alloy plates present certain technical challenges. Below are the primary methods and considerations for cutting and forming TZM alloy plates:

Cutting Methods

Given the high hardness and low ductility of TZM molybdenum alloy, common cutting methods include mechanical cutting, electrical discharge machining (EDM), and laser cutting.

1.Mechanical Cutting: Utilizes carbide tools or diamond tools for cutting, suitable for thinner TZM plates. During the cutting process, it is essential to ensure sharp tools and moderate cutting speed to avoid tool damage or cracks on the material surface.

2.Electrical Discharge Machining (EDM): Ideal for cutting thicker or more complex-shaped TZM plates, ensuring high precision and a smooth cutting surface.

3.Laser Cutting: Suitable for high-speed cutting of thin plates, offering high efficiency, precision, and quality edges. However, heat input must be controlled to avoid localized overheating of the material.

Forming Processes

The forming of TZM molybdenum alloy plates mainly involves a combination of cold and hot processing techniques.

1.Cold Processing: Includes processes such as stamping and bending. Due to the low ductility of TZM molybdenum alloy, cold processing should be performed under low strain conditions, and lubricated molds should be used to minimize the risk of crack formation.

2.Hot Processing: Includes processes such as hot rolling and hot pressing. These are typically performed at high temperatures ranging from 1200°C to 1500°C to improve the plasticity and processability of the material. Uniform heating is necessary to prevent deformation or stress concentration due to uneven temperatures.

Considerations

When cutting and forming TZM alloy plates, excessive heat input or processing stress should be avoided to prevent material performance degradation or the formation of micro-cracks. Post-processing annealing or heat treatment is recommended to relieve stress and optimize the mechanical properties of the material.

With scientifically designed cutting and forming processes, TZM alloy plates can be efficiently processed into various complex shapes to meet the stringent requirements of different industrial applications.

Why TZM Alloy Is an Indispensable Material in High-temperature Industrial Applications?

TZM molybdenum alloy is a high-performance alloy based on molybdenum, with small amounts of titanium (Ti), zirconium (Zr), and carbon (C) added. Its name derives from the initials of these additive elements. As an advanced material widely used in aerospace, nuclear industries, and high-temperature industrial applications, TZM alloy is renowned for its exceptional melting point and high-temperature performance.

Molybdenum itself is a high-melting-point metal, with a melting point of 2623°C. The melting point of TZM molybdenum alloy, enhanced by the addition of trace elements, is comparable to that of pure molybdenum, exceeding 2600°C. This enables TZM alloy to maintain excellent structural stability in extreme high-temperature environments. The addition of titanium and zirconium not only reinforces the molybdenum matrix's grain structure but also improves the alloy's oxidation resistance and high-temperature strength, making its overall performance under high-temperature conditions far superior to pure molybdenum.

In terms of high-temperature performance, TZM molybdenum alloy demonstrates exceptional creep resistance and thermal stability. Even in high-temperature environments ranging from 1200°C to 1400°C, TZM alloy retains its mechanical strength and deformation resistance. Its creep life is significantly longer than that of pure molybdenum and other molybdenum alloys. Thanks to the dispersion strengthening effect of carbides within the alloy, its high-temperature creep resistance is further enhanced, making it ideal for applications in high-temperature furnace components, rocket nozzles, molds, and nuclear reactor components under extreme conditions.

However, TZM molybdenum alloy also has limitations. For instance, it is prone to forming volatile oxides in oxidizing environments. As a result, it is typically used in vacuum or protective atmospheres, or with protective coatings to extend its lifespan. Overall, due to its high melting point and outstanding high-temperature performance, TZM molybdenum alloy is an indispensable material in high-temperature industrial applications.

Cu/Mo/Cu Carrier Price in Late January 2025

16x11x0.5mm Cu/Mo/Cu carrier price is 4.50 USD/PC in the second half of January 2025. These carriers are mainly used in radio frequency, microwave and semiconductor high-power devices, carriers, lead frames, low-expansion layers and heat conduction channels of multilayer printed circuit boards (PCBs).

Cu/Mo/Cu carrier (CMC) is a composite material with a similar sandwich structure, the core material is molybdenum, and both sides are covered with copper. The basic concept of the design is to use the high thermal conductivity of copper and the low thermal expansion characteristics of molybdenum. By adjusting the thickness ratio of copper, molybdenum and copper, it can achieve a thermal expansion coefficient matching ceramic materials and semiconductor materials, and a higher thermal conductivity. The expansion coefficient and thermal conductivity are designable.

The ideal carrier material should have a linear expansion coefficient CTE, which is basically matched with the chip, and has the highest possible thermal conductivity, especially the Z-direction (thickness) thermal conductivity, so that the heat of the packaged chip and other electronic devices can be quickly discharged. In order to increase its power density, achieve high power, reduce the volume and realize the miniaturization of the device. CMC material is now the one of the materials to meet above requirements.

Molybdenum Ring Price in Early January 2025

φ108.4*φ102.5*70mm molybdenum ring price is USD150.00/PC, EXW XIAMEN, CHINA in the first half of January 2025.

Corrosion resistance, creep resistance and high temperature performance make molybdenum made rings very suitable for high temperature crystal growth processes. When sapphire is easy to extract, higher sapphire yield and quality can be achieved. The molybdenum-based ring has heat resistance and a smooth surface, making it durable and cost-effective.

The surface roughness of the molybdenum ring needs to be higher than 1.6 µm. When the surface of the ring is rough, the sapphire is not easy to take out and it is easy to damage the crystal. In addition, the ring will be damaged in the process. Chinatungsten Online's ultra-smooth ring eliminates these problems. Sapphire manufacturers can benefit from this product because it eliminates complex and expensive processes. In addition, the smooth surface is resistant to corrosion caused by aggressively molten sapphire. This function can extend the service life of reusable rings.

Moly rings for sapphire growth furnaces are available with a variety of dimensions including round, in numerous standard diameters and wall thicknesses. Custom configurations are available. In addition, many other components for these furnaces are also customized.
