Tungsten alloy collimators, primarily composed of tungsten with nickel, iron, and other elements, exhibit density characteristics surpassing those of collimators made from other materials, giving them a significant advantage in radiation shielding and wide application in the medical field. The application advantages of tungsten alloy collimators include strong radiation shielding capability, excellent radiation durability, environmental friendliness, and superior chemical stability.

Tungsten alloy collimator is a radiation control device designed using high-density tungsten alloy materials, with its core function being to limit the direction and range of radiation propagation through physical structures. It is widely used in medical, industrial, and scientific fields.

The rise in tungsten prices has an uneven impact on various segments of the industrial chain, presenting a "smile curve":

Capital and market sentiment have played a significant role in amplifying fluctuations in this round of price increases. Market data shows that capital has played a significant role in driving tungsten price increases. Price updates are quickly reflected within hours through share price fluctuations of related concept stocks in the secondary market.

China accounts for approximately 83% of global tungsten concentrate production (according to 2025 USGS data), with deep processing accounting for an even higher proportion, exceeding 90%, giving it a dominant position in the global tungsten supply chain. The export controls implemented on February 4, 2025, and the tightening supply, forced the global supply chain to reassess its reliance on China's supply chain. As of September 30, 2025, European APT prices had risen to USD 580-650/mtu (RMB 366,000-410,000/ton), an 86.4% year-to-date increase. Due to the extended export approval period and uncertainty in China, overseas purchasing has been disrupted, resulting in a significant reduction in inventories and further exacerbating global market tensions. Although overseas tungsten mine development projects (such as Sangdong in South Korea and Mactung in Canada) are progressing, production is limited and far from sufficient to offset the impact of reduced Chinese supply.

National policies, combining "domestic mining control and foreign export regulation," have significantly impacted the supply and demand structure of the tungsten market.

In 2025, the tungsten supply side saw a significant tightening, primarily driven by policy-driven quota controls and multiple external factors.

Since March 2025, China's tungsten prices have continued to rise, with a temporary surge in August, reaching a historical peak in early September, and doubling the price of major tungsten products this year.

Tungsten is widely used in a variety of fields due to its exceptional hardness, wear resistance, high temperature resistance, corrosion resistance, and high density. Tungsten's uses include:

Tungsten is a silvery-gray transition metal with the element symbol W and atomic number 74. It has a high melting point (3422°C), high density (19.35 g/cm³), high hardness, and excellent high-temperature resistance. It is widely used in aerospace, defense, electronics, electric light sources, and cemented carbide.
