Molybdenum rods are commonly used in various industrial applications due to their high melting point, excellent strength, and good thermal and electrical conductivity. While there are different types of molybdenum rods available, they are primarily categorized based on their composition and specific properties. Here are some common types of molybdenum rods:

1. Pure Molybdenum Rods: These rods are made from pure molybdenum, which typically has a high purity level of 99.95% or higher. Pure molybdenum rods are known for their excellent thermal conductivity, high tensile strength, and resistance to corrosion. They are often used in high-temperature environments, such as in furnaces, aerospace applications, and electrical contacts.

2. TZM Molybdenum Rods: TZM (Titanium-Zirconium-Molybdenum) rods are alloyed with small amounts of titanium and zirconium, along with pure molybdenum. The addition of these alloying elements enhances the high-temperature strength, creep resistance, and recrystallization resistance of the rods. TZM molybdenum rods find applications in aerospace industries, defense, and high-temperature furnace components.

3. Lanthanated Molybdenum Rods: Lanthanated molybdenum rods, also known as lanthanum-doped molybdenum rods, contain a small amount of lanthanum oxide (La2O3). This doping improves the high-temperature strength, recrystallization resistance, and ductility of the molybdenum rods. Lanthanated molybdenum rods are commonly used in glass melting electrodes, furnace components, and electrical applications.

4. Molybdenum-Lanthanum (MoLa) Rods: These rods are a composite material consisting of a molybdenum matrix with dispersed lanthanum oxide particles. MoLa rods exhibit enhanced creep resistance, high-temperature strength, and improved resistance to oxidation compared to pure molybdenum rods. They are utilized in applications like glass industry electrodes, sintering boats, and vacuum furnaces.

5. Molybdenum-Copper (MoCu) Rods: MoCu rods are composed of a molybdenum matrix with a copper content. The copper acts as a strengthening agent, increasing the thermal conductivity and electrical conductivity of the rods. MoCu rods are widely used in heat sinks, electronic packaging, and high-power devices where efficient heat dissipation is crucial.
