CTIA GROUP LTD tungsten resin is a composite material made from tungsten powder and a resin matrix (such as polyethylene, epoxy resin, or other polymer materials), widely used in radiation shielding, fishing gear, and biomimetic materials. The preparation methods for tungsten resin vary depending on the matrix type, tungsten powder content, and application requirements, with common techniques including injection molding, compression molding, press-sintering, and high-speed mixing-calendering.

Tungsten-nickel-iron alloy (W-Ni-Fe alloy), also known as high-density tungsten alloy, is a composite material with tungsten as the primary component and nickel and iron as binding phases. Typically containing over 90% tungsten, with the remainder a mixture of nickel and iron (e.g., typical ratios like 95W-3Ni-2Fe or 93W-5Ni-2Fe), this alloy is valued for its high density (16.5-18.5 g/cm³), high strength, corrosion resistance, and good machinability, finding wide use in defense, aerospace, medical, and industrial fields. The question raised by users concerns whether this alloy exhibits magnetic properties.

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.
