Magnetic Properties of Tungsten-Nickel-Iron Alloy 5

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…

What Is Tungsten Alloy Collimator? 7

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. Tungsten alloy is a material based on tungsten (W) with the addition of metals such as nickel (Ni) and iron (Fe), achieving a density of 16.5-18.75 g/cm3. This high-density characteristic makes it an ideal material for radiation shielding: Radiation…

What Impact Does the Tungsten Prices Surge Have on the Industrial Chain? 11

The rise in tungsten prices has an uneven impact on various segments of the industrial chain, presenting a “smile curve”: Upstream (Mining/Smelting) Profit margins are highest. Large mining companies with quotas benefit from significantly higher selling prices, leading to significant improvements in gross profit margins. For example, Xiamen Tungsten has significantly increased its resource self-sufficiency rate through asset injections. In the first half of 2025, tungsten and molybdenum revenue accounted for 46.21%, benefiting from a year-on-year increase of over 68%…

How Much Influence Do Capital and Funding Have on Tungsten Price? 11

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. According to China Tungsten Online’s daily tungsten price data on WeChat, the APT price rapidly approached the RMB 400,000/ton mark from RMB 290,000/ton in mid-to-late August, reaching a…

What Are the International Market Factors Behind the Tungsten Price Surge? 30

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…

How Do National Policies Affect Tungsten Prices? 18

National policies, combining “domestic mining control and foreign export regulation,” have significantly impacted the supply and demand structure of the tungsten market. On February 4, 2025, the Ministry of Commerce and the General Administration of Customs issued an announcement imposing export controls on various tungsten products and related technologies, including ammonium paratungstate (APT), tungsten oxide, and tungsten carbide. Export licenses require specific end-users and intended uses, strengthening review and oversight. Based on practical experience, the approval process has been extended…

What Supply Side Factors are Behind the Surge in Tungsten Prices? 7

In 2025, the tungsten supply side saw a significant tightening, primarily driven by policy-driven quota controls and multiple external factors. The first batch of tungsten mining quotas for 2025 is 58,000 tons (based on 65% WO?), issued by the Ministry of Natural Resources (the document was issued on April 3, 2025, and the relevant allocation table will be made public in mid-to-late April). Compared with the first batch of indicators for 2024, this quota has been reduced by 4,000 tons,…

Why Did Tungsten Prices Suddenly Rise in 2025? 32

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. As of the end of September 2025, despite some decline, the price of 65% wolframite concentrate had risen rapidly from RMB 143,000/ton at the beginning of the year. After peaking at RMB 288,000/ton in early September, it fell back to RMB 271,000/ton, still up approximately 89.5% from…
