Tungsten molybdenum alloy (such as Mo-30W) has become the preferred material for key components in semiconductors, photovoltaics, and high-temperature furnaces due to its excellent high-temperature strength, creep resistance, and corrosion resistance. In recent years, with the rapid development of 5G, artificial intelligence, and new energy industries, the demand for tungsten molybdenum alloys has continued to rise.

Core application areas

Semiconductor manufacturing:

Used for heaters, crucibles, and sputtering targets in wafer processing, it is resistant to high temperatures (>1500 ℃) and does not react with silicon, ensuring high-purity wafer production.

In extreme ultraviolet lithography (EUV) equipment, the tungsten molybdenum alloy mirror support structure can reduce thermal deformation and improve lithography accuracy.

Photovoltaic industry:

As a thermal field material for polycrystalline silicon ingot furnaces (such as insulation screens and heating electrodes), its lifespan is more than three times that of traditional graphite materials.

In perovskite solar cells, tungsten molybdenum alloy electrodes can withstand high-temperature annealing processes to improve conversion efficiency.

High temperature industrial furnace:

The heating element and insulation screen used in sintering furnaces and sapphire crystal growth furnaces maintain stable performance at 1800 ℃.

Technological breakthrough

Powder Injection Molding (PIM): Achieving near net forming of tungsten molybdenum alloy components with complex shapes, reducing machining losses.

Surface coating technology: By coating with silicides or rare earth oxides (such as Y ₂ O3), the oxidation resistance is further enhanced and the service life is extended.

With the popularization of third-generation semiconductors (SiC/GaN) and new photovoltaic technologies, the tungsten molybdenum alloy market is expected to grow at an average annual rate of 8%, becoming the "invisible pillar" of the high-tech industry chain.
