Molybdenum TZM applications in high-temperature industries include casting molds, furnace components, X-ray anode targets, and hot runner nozzles. With its excellent mechanical properties, high-temperature resistance, and corrosion resistance, TZM alloy provides durability, stability, and a long lifespan for components required to work under high-temperature environments.
TZM Casting Parts
TZM alloy is an excellent material for various applications in metal casting molds that require durability, thermal conductivity, and low thermal expansion rates. TZM has a high melting point, a thermal conductivity range of 20-60 W/m·K, and a thermal expansion rate range of 4.5-6.0 × 10^-6/℃.
Even at 1300 degrees Celsius, TZM casting parts, such as mold inserts, mold cores, and casting molds, retain high thermal conductivity ranging from 5-20 W/m·K, with thermal expansion rates ranging from 10-15 × 10^-6/℃. These properties allow TZM casting parts to attain required temperatures quickly and cool down rapidly after use.
TZM casting parts have dimensional stability and resist cracking due to thermal stress from significant temperature changes. They can also withstand multiple high-temperature uses without performance degradation. TZM casting molds made from TZM plates and rods have high-temperature hardness and resistance to corrosion and erosion, resulting in longer service life.
TZM Furnace Components
TZM furnace components have many applications in various high-temperature working environments, as they can improve the sintering, heat treatment, and welding capabilities of high-temperature isostatic pressing (HIP) furnaces. These components exhibit high-temperature and corrosion resistance; excellent mechanical properties; and a long lifespan, making them suitable material for heat treatment equipment in various high-temperature working environments.
Compared to molybdenum, strengthened TZM materials exhibit better resistance to creep, higher recrystallization temperature, and greater high-temperature strength. This is due to the formation of titanium and zirconium solid solutions, as well as second-phase particles formed by various MoZr, MoTi, and carbides. By increasing the lattice dislocation density, these particles increase recrystallization temperature and strength of TZM. TZM furnace components, able to withstand the huge and rapid temperature changes in high-temperature furnaces, are used as furnace heating conductors; shields; charge carriers; furnace nuts; screws; rivets; and boats and trays in hot isostatic pressing and sintering furnaces.
TZM X-ray Anode Target
TZM alloy’s high-temperature performance, corrosion resistance, and ability to withstand heat stresses make it an ideal material for X-ray anode targets. During scan, a metal disc rotating at 3,000 to 10,000 RPM, these targets can reach surface temperatures exceeding 2,000℃. TZM alloy extends anode target life significantly, while its high atomic number promotes efficient, high-quality X-ray imaging.
TZM Hot Runner Nozzles
TZM hot runner nozzles are an excellent choice for many applications in high-temperature, high-pressure injection molding processes. TZM hot runner nozzles display outstanding resistance to heat, corrosion and oxidation, ideal properties in continuous high-temp production environments. In addition, the precise channels of TZM hot runner nozzles ensure stable control of flow rate and pressure when working with plastic materials. This results in improved product quality and stability; low maintenance costs; and long service life. TZM hot runner nozzles are an economical choice.
