TZM Moly Alloy Bar

Product Description

Overview

TZM Alloy is a molybdenum-based high-temperature alloy with molybdenum (Mo) as the matrix, titanium (Ti), zirconium (Zr) and trace carbon (C) added, with a typical composition of Mo-0.5Ti-0.08Zr-0.02C. Its core strengthening mechanism is to achieve solid solution strengthening and dispersion strengthening through dispersed phases such as TiC and ZrC formed by titanium, zirconium, and carbon, which significantly improves the high-temperature performance and stability of the material. Our company can accept customized product processing.

Features

TZM Moly Alloy Bar has become the best material choice for high temperature, high corrosion and high precision fields due to its comprehensive advantages such as high temperature strength, corrosion resistance, thermal shock resistance, and easy processing. Although its cost is higher than pure molybdenum, its performance significantly improves the reliability and service life of the equipment, especially in high-end manufacturing and extreme environments.

1. Excellent high temperature strength and creep resistance
The recrystallization temperature of TZM alloy is as high as 1350~1700℃, which is 500~450℃ higher than pure molybdenum, and the tensile strength remains 700~720MPa at 1000℃. This characteristic enables it to withstand loads for a long time in high-temperature environments (such as aircraft engine combustion chambers and nuclear reactor structures) without creep deformation, and can avoid embrittlement caused by recrystallization.

2. Excellent corrosion resistance
TZM alloy has excellent corrosion resistance to molten metals (such as zinc, aluminum) and glass melts. In injection molding, it is not easy to leave residual materials on its surface, which can effectively prevent the appearance of gate marks and salivation in the products. At the same time, it also has good tolerance to chemical media such as acids and alkalis, and is suitable for corrosion-resistant parts of chemical equipment.

3. High thermal shock resistance and thermal stability
The thermal conductivity of the material is 126W/(m・K), and the thermal expansion coefficient is only 5.3×10⁻⁶/K5. It can withstand rapid heating and cooling without cracking. In addition, its electrical and thermal conductivity is close to that of pure molybdenum, which is suitable for scenes requiring efficient thermal management.

4. Good processing performance and structural stability
TZM bars can be made into complex shapes through forging, cold rolling, machining and other processes. Its cold working hardening effect is significant. After proper heat treatment, a fibrous microstructure can be obtained, which has both high strength and toughness and can meet high-precision dimensional requirements.

5. Lightweight and comprehensive performance advantages
The density is about 40% lighter than tungsten alloy, but the strength and melting point are comparable to pure molybdenum. This property enables lightweight design in the aerospace field while still ensuring structural strength.
