Products Description
An alloy composed of tungsten and molybdenum. Commonly used tungsten-molybdenum alloys contain 30% to 50% tungsten (by mass). Tungsten molybdenum alloys containing 30% tungsten (by mass) have excellent corrosion resistance to liquid zinc and are used in the manufacture of stirrers, pipe and vessel linings and other components in the zinc refining industry.
Tungsten-molybdenum alloy rods are versatile, high-performance alloy materials. With their exceptional high-temperature properties, corrosion resistance, mechanical strength, and machinability, they are widely used in various fields such as aerospace, electronics industry, high-temperature furnace components, zinc smelting, and mechanical processing. These alloy rods can be customized according to customers' specific requirements, meeting diverse industrial application demands. They represent a highly valuable high-performance material.
Tungsten-molybdenum alloy rods are produced in the same way as molybdenum metal and molybdenum alloys, i.e., both powder metallurgy post-sintering processing and smelting processing to produce rods, plates, wires or other profiles.

Features of Tungsten-molybdenum alloy rods
High Melting Point: Tungsten-molybdenum alloys have an extremely high melting point, typically above 2500°C, allowing them to maintain stable structure and performance in high-temperature environments without melting or deforming easily.
High Thermal Conductivity: They exhibit excellent thermal conductivity, enabling efficient heat dissipation and preventing localized overheating, thereby extending component lifespan.
Low Thermal Expansion Coefficient: With a low thermal expansion coefficient at high temperatures, these alloy rods experience minimal dimensional changes, ensuring high precision in applications with temperature fluctuations.
Resistance to Molten Metals: They demonstrate exceptional corrosion resistance against aggressive media such as molten zinc, making them ideal for industries like zinc smelting, where they effectively withstand erosion.
Oxidation Resistance: In high-temperature oxidizing environments, tungsten-molybdenum alloys form a dense oxide layer that protects the base material from further oxidation, enhancing durability.
High Strength and Hardness: The alloys possess superior strength and hardness, enabling them to withstand significant mechanical stress, making them suitable for high-strength components.
Good Creep Resistance: Under high-temperature and high-stress conditions, they exhibit low creep rates, minimizing deformation over time.
Ease of Machining: Compared to pure tungsten, tungsten-molybdenum alloys have moderate hardness, making them easier to machine (e.g., turning, milling) and suitable for high-precision manufacturing.
Weldability: Under specific conditions, these alloys can be welded to other metals, broadening their application scope.
High Density: While dense, they are slightly less dense than pure tungsten, making them advantageous for applications requiring high-density materials (e.g., aerospace counterweights) while remaining manageable for machining and use.
Applications of Tungsten-molybdenum alloy rods
Aerospace Applications:
Rocket Engine Components: Used to manufacture critical parts such as gas rudders and protective shields in rocket engines. These components must operate in high-temperature, high-pressure, and highly corrosive environments, making tungsten-molybdenum alloys an ideal material due to their high melting point, excellent thermal conductivity, and low thermal expansion coefficient.
Aircraft Engine Blades: In aviation engines, tungsten-molybdenum alloys can be used to produce high-temperature turbine blades. Their superior creep resistance and high-temperature strength ensure stable engine operation under extreme heat.
Electronics Industry:
Electron Tube Grids: Used in the production of electron tube grids, where their excellent electrical and thermal conductivity ensures efficient performance.
Light Bulb Support Filaments: Tungsten-molybdenum alloy rods serve as support filaments in light bulbs, with their high melting point and ablation resistance extending bulb lifespan.
High-Temperature Furnace Components:
Structural Parts for High-Temperature Furnaces: Due to their high-temperature strength and low vapor pressure, these alloys are used in furnace bodies, hearth plates, and other structural components that must endure mechanical stress in extreme heat.
Heating Elements: Tungsten-molybdenum rods are also employed as heating elements in high-temperature furnaces, thanks to their excellent electrical conductivity and oxidation resistance at elevated temperatures.
Zinc Smelting Industry:
Agitators: Used in zinc smelting agitators, their corrosion resistance against molten zinc ensures long-term stability in high-temperature, highly corrosive environments.
Pipeline and Vessel Linings: Applied in pipelines and container linings for zinc smelting, effectively resisting molten zinc erosion and extending equipment service life.
Machining and Tooling:
High-Precision Molds: Tungsten-molybdenum alloy rods are used to manufacture high-precision molds, where their high strength and hardness ensure durability and dimensional accuracy.
Cutting Tools: In machining, these alloys are used to produce cutting tools, benefiting from their wear resistance and impact toughness to enhance tool longevity and processing efficiency.
FAQ
Are you a factory or manufacturer?
Yes, we are a factory but generally, we use our trading company to handle the business abroad. It will be convenient to receive the remittance and arrange the shipment.
What is the delivery method?
A: Generally, we send cargo by UPS, DHL or FedEx. Also, we can send by sea to seaport or by air to the closest airport.
Why Is Your Product So Cost-Effective?
We cut out the middlemen in the end-to-end manufacturing process. Rather than obtaining semi-finished goods from other suppliers, we obtain our raw material of APT powder directly from its source.
