1. What is molybdenum alloy?
Molybdenum alloy, English name: molybdenumalloy, Mo alloy, is a non-ferrous alloy composed of molybdenum as the matrix and adding other elements. The main alloying elements are nickel (Ni), copper (Cu),titanium.html> titanium (Ti), zirconium (Zr), hafnium (Hf), tungsten (W) and rare earth elements. The addition of alloying elements not only acts as a solid-solution strengthening effect on the molybdenum alloy and maintains the low-temperature plasticity of the alloy, but also forms a stable and dispersed carbide phase to increase the strength and recrystallization temperature of the alloy. The main strengthening methods of molybdenum alloys are solid solution strengthening, precipitation strengthening and work hardening. Molybdenum alloy sheets, strips, foils, pipes, rods, wires and profiles can be produced through plastic processing, and their strength and low-temperature plasticity can also be improved.
2. What are the characteristics of molybdenum alloy?
Molybdenum alloys are characterized by high density, high melting point, low vapor pressure, low thermal expansion, enhanced hot strength, toughness and corrosion resistance.
3. What kinds of molybdenum alloys are there?
Molybdenum alloys can be divided into the following categories according to the alloy metal elements:
1. Binary molybdenum alloys: mainly tungsten-molybdenum alloy (W-Mo), molybdenum-copper alloy (Mo-Cu), molybdenum-zirconium alloy (Mo-Zr), molybdenum-titanium alloy (Mo-Ti), molybdenum-lanthanum alloy ( Mo-La), molybdenum-yttrium alloy (MoY), molybdenum-rhenium alloy (Mo-Re), chrome-molybdenum alloy (Mo-Cr), etc.
2. Multi-element molybdenum alloy:
Mo-Ti-Zr-C series: The main grades are TZC and TZM.
Mo-Hf-Zr-O series: mainly ZHM, ZHM4, ZHM6, ZHM7, ZHM8, etc.
Mo-W-Hf-C series and Mo-W-Hf-Zr-C series: mainly M25WH1, M25WH2, HWM25, M25WZH1.
3. Doped molybdenum alloy: Adding a certain amount of potassium, silicon, and aluminum elements to pure molybdenum can greatly increase the recrystallization temperature of molybdenum, and it still has good plasticity even after recrystallization.
According to the strengthening type, molybdenum alloys can be divided into the following categories: solid solution strengthening alloys of alloying elements, dispersion strengthening alloys, doping strengthening alloys and comprehensive strengthening alloys.

5. Application of Rare Earth Molybdenum Alloy
The addition of rare earth elements can not only increase the recrystallization temperature and high temperature creep resistance of molybdenum, but also significantly reduce the plastic-brittle transition temperature of molybdenum, increase ductility, and improve room temperature brittleness and high temperature sag resistance of molybdenum.
1. Rare earth molybdenum wire is mainly used as electric light source filament, EDM electrode and high temperature furnace heating element, etc.;
2. Rare earth molybdenum plates and sheets are used for stamping into wafers for silicon controlled rectifiers, as well as heat insulation shields and guide sheets for electronic tubes;
3. Rare earth molybdenum alloys can be used as high-quality steel hot-piercing plugs, as well as aerospace and nuclear industry materials, X-ray pole targets, die-casting molds and extrusion molds;
4. Rare earth molybdenum special-shaped products are used as glass melting electrodes, rare earth smelting electrodes, crucibles, high-temperature sintering boats, high-temperature radiation heat shields, orifices, guide rails, backing plates, etc.;
5. Rare earth molybdenum alloys can also be used as hot cathode materials for medium and high-power electronic tubes. The rare earth molybdenum alloy hot cathode material replaces the current high working temperature, radioactive pollution, and brittle thoriated tungsten cathode, which can greatly reduce the working temperature of the electron tube and improve reliability.
