Overview of Tungsten Applications
Tungsten, as a strategic metal resource, has demonstrated significant application value in multiple high-tech and emerging fields due to its excellent properties such as high melting point, high hardness, and high density. In recent years, its applications in photovoltaics, aerospace and defense, semiconductors and electronic devices have been particularly prominent. In the photovoltaic field, tungsten wire diamond saws, with their high hardness, high strength, and low breakage rate, have gradually replaced traditional carbon steel wires and become the mainstream material for silicon wafer cutting, significantly improving cutting efficiency and reducing silicon wafer loss, thereby contributing to cost reduction and efficiency enhancement in the photovoltaic industry. In the aerospace and defense sectors, porous tungsten is used in the emitter of space propulsion systems, while tungsten alloys are employed in the manufacturing of armor-piercing projectile cores, missile guidance components, armor materials, and the first wall materials of nuclear fusion reactors, showcasing its outstanding performance in extreme environments. In the semiconductor and electronic device field, porous tungsten serves as the framework material for diffusion-type barium tungsten cathodes, influencing the lifespan and stability of vacuum electronic devices. Tungsten carbide is utilized in wafer cutting tools and semiconductor packaging materials, enhancing chip yield.
In the high-end manufacturing sector, tungsten carbide-based hard alloys are widely used in cutting tools, molds, and wear-resistant components, with particularly strong demand in the automotive, machine tool, and 3C electronics industries. Meanwhile, tungsten and tungsten alloy powders are also employed in 3D printing for aerospace, medical, and other fields to manufacture complex structural components. In the new energy and energy storage sector, tungsten-copper composites are utilized as electrode materials in new energy vehicle batteries, enhancing their conductivity and safety. Tungsten-based catalysts hold potential application value in hydrogen fuel cells, contributing to the development of the hydrogen energy industry.
In the medical field, tungsten alloys are used in collimators and protective components of medical radiotherapy equipment due to their high density and radiation shielding properties. Their biocompatibility and high strength also make them promising for use in orthopedic implants. Additionally, in high-temperature and extreme environment applications, porous tungsten is utilized in high-temperature scenarios such as electrical contacts and missile throat linings to enhance heat dissipation uniformity and anti-ablation capabilities. It is also employed as a high-temperature filtration medium in high-temperature fluid filters in industries such as chemical engineering and metallurgy.
