This week, the tungsten market showed a divergent trend with mild corrections in domestic prices and a contrarian rise in overseas APT prices. Domestic tungsten concentrate and midstream product prices remained relatively firm, while scrap tungsten prices dropped sharply as profit-taking emerged. Supported by a tight supply-demand balance, overseas markets strengthened, further widening the price gap between domestic and international markets.

[SMM Magnesium Weekly Review: Magnesium Market Held Up Well, With Cost Support and a Tug-of-War Between Sellers and Buyers Continuing] This week, the overall magnesium industry chain held up well, with prices of all products generally raised. The raw material dolomite market remained stable, with ample supply and steady demand. Magnesium ingot prices consolidated at highs. At the beginning of the week, supported by rising energy costs such as ferrosilicon and coke and tight spot availability, prices jumped by 300 yuan/mt. Subsequently, downstream fear of high prices emerged, transactions failed to keep pace, and prices consolidated at highs. In foreign trade, the center of magnesium ingot FOB quotes moved up to $2,440-2,470/mt. Wait-and-see sentiment outside China remained strong, but influenced by bullish expectations in China, forward orders were gradually locked in. Magnesium powder prices remained firm, with strong cost support. Export data increased YoY, while domestic trade was mainly driven by just-in-time procurement. The benchmark price of magnesium alloy held up well, but the release of new capacity led to increased supply, processing fees stayed in the doldrums, and the market showed a pattern of strong supply and weak demand. Overall, cost support remained the core driver behind magnesium prices fluctuating at highs, while downstream acceptance of high prices was limited, and the market may continue this tug-of-war in the short term.

Middle East tensions have sparked a massive steel trade "mismatch." Iran's blocked exports created a 2.3-million-ton billet vacuum in Southeast Asia, while the Red Sea crisis stalled China's flat steel shipments to the Gulf. Consequently, China and India are rapidly absorbing SEA's diverted billet orders. SMM projects that blocked flat steel returning to China's domestic market, combined with surging overseas billet demand, will accelerate the narrowing of the domestic HRC-rebar spread.

As a niche yet high-strategic rare metal, hafnium (Hf, atomic number 72) lags behind common metals like copper in public awareness, but its unique physicochemical properties make it irreplaceable for nuclear power, aerospace, semiconductors and other high-end fields. This concise breakdown covers its core traits, supply dynamics and critical applications to highlight its underrecognized role in advanced manufacturing. I. Core Properties A silver-gray, high-melting-point transition metal, hafnium exists solely as a zirconium-associated metal—no independent ore deposits. The near-identical atomic radius and chemical properties of zirconium and hafnium make separation/purification highly challenging, the root of its scarcity.Key strengths for harsh industrial use: 2233℃ melting point, exceptional high-temperature oxidation/structural stability Strong room-temperature plasticity, balanced strength and toughness Superior corrosion resistance (insoluble in dilute acids/alkalis, soluble only in hydrofluoric acid/aqua regia) ~600x higher thermal neutron absorption than zirconium (ideal for nuclear reactor control) High dielectric constant of hafnium oxide (critical for advanced semiconductors) Carbides/nitrides (melting point >2900℃) for ultra-high-temperature ceramics and hard alloys II. Supply & Scarcity Resources: Extremely scarce (crustal abundance ~3 ppm), exclusively tied to zirconium ores. Global resources concentrated in Australia, South Africa, the U.S. and Brazil; China faces low hafnium content in domestic zirconium ores, leading to high external dependence. Supply: Production hinges on zirconium smelting, with zirconium-hafnium separation as a core technical barrier. Only a handful of global players produce high-purity (nuclear/electronic-grade) hafnium at scale, forming an oligopoly. Annual output is ~hundreds of tons, with ultra-low supply elasticity—supply disruptions trigger sharp price swings. Ⅲ. Irreplaceable Core Applications Demand is rigid (no cost-effective substitutes) across high-end sectors: Nuclear Industry: Preferred material for pressurized water reactor control rods, regulating reaction rates and ensuring safety. Driven by global nuclear power revival, demand is steadily growing. Aerospace: Key nickel-based single-crystal superalloy additive, boosting high-temperature creep strength and lifespan for aero-engine turbine blades, combustors and rocket nozzles. Semiconductors: High-purity electronic-grade hafnium oxide overcomes silicon dioxide’s miniaturization limits, reducing leakage current and enabling advanced-node chip production—a key growth driver. Other High-End Fields: Used in cutting tool coatings, special electronic components, corrosion-resistant materials and emerging hydrogen storage research, with expanding use cases. Ⅳ. Conclusion Hafnium is a "scarce niche metal with rigid high-end demand," holding irreplaceable strategic value in China’s key industries (nuclear power, aerospace, semiconductors). The global market remains in long-term tight supply-demand balance, and its strategic and market value will rise alongside global advanced manufacturing upgrades.

This week, ferrous metals rebounded from the bottom. At the start of the week, coking coal and coke led the futures higher, mainly driven by rising crude oil prices in the overseas market, which pushed the energy and chemicals sector stronger accordingly; mid-week, both the U.S. and Iran signaled a more relaxed stance toward war, easing geopolitical tensions, while coal prices fell in tandem, weakening the cost-side logic, and ferrous metals fluctuated at highs; in the latter half of the week, worsening short-term liquidity issues in BHP's iron ore port inventory triggered stronger iron ore prices in the overseas market, while the Middle East situation remained volatile, reinforcing cost support and pushing ferrous metals higher again. In the spot market, supported by futures, end-user and arbitrage purchase sentiment both improved WoW this week......

Among precious and rare metals, osmium is a niche yet irreplaceable material, overshadowed by gold, silver, platinum and palladium but critical for high-end industry and scientific research thanks to its unique physical and chemical properties. This report breaks down osmium’s core attributes, supply, applications and market traits to unveil the “densest natural metal”. I. Basic Profile: A Distinct Platinum Group Metal Osmium (Os, atomic number 76) is a Group Ⅷ transition metal and part of the platinum group metals (PGMs), extremely scarce in nature. It has no independent deposits, only extracted and purified via platinum ore smelting alongside platinum, iridium, ruthenium, rhodium and palladium, ruling out large-scale standalone mining. Its standout properties: unmatched density (22.59g/cm³ at 20℃, higher than gold and platinum), exceptional heat resistance (melting point 3033℃, boiling point over 5000℃), and high hardness & corrosion resistance (Mohs hardness 7). It is highly brittle with poor plasticity, mostly used in powder or alloy forms. Key Safety Warning: Osmium oxidizes to toxic, volatile osmium tetroxide (OsO₄) when heated above 100℃ in air. Full-process operations (smelting, storage, transport, processing) require inert gas protection, raising production and application thresholds. II. Supply Landscape: Extreme Scarcity & Monopolized Output Osmium is far rarer than gold and platinum, with a crustal abundance of just 0.001ppm, one of the lowest stable elements globally. Proven recoverable reserves are extremely limited and highly concentrated. Global output hinges entirely on platinum mining and smelting, staying at a tiny scale: annual global production is roughly 1 ton (data from International Platinum Group Metals Association), while China’s annual output is less than 100kg. South Africa and Russia dominate global osmium resources and smelting capacity, forming a highly monopolized, inelastic supply market. Tight supply-demand balance persists, supporting strong price resilience and volatility. III. Core Applications: High-End & Irreplaceable Scenarios Despite low production and narrow application scope, osmium is a rigid material for high-precision sectors with no low-cost substitutes, focusing on four key fields: Special Hard Alloys: Osmium-based alloys excel in hardness, wear and corrosion resistance, used for high-precision bearings (luxury watches, instruments), premium pen nibs, medical scalpels and high-end mechanical wear parts. Industrial Catalysis: Osmium and its compounds act as high-efficiency catalysts for fine chemical and organic synthesis (hydrogenation, oxidation), boosting process efficiency and product purity with stable low-volume demand. Scientific Research: Toxic osmium tetroxide is an irreplaceable stain for electron microscopy samples in materials and life sciences; high-purity osmium powder serves as a specialty lab consumable. Aerospace & Military: Leveraging high density and thermal stability, osmium is used for specialty high-temperature components, precision guidance parts and high-end electrical contacts, with high added value and growing demand amid industrial upgrading. IV. Core Market Traits Osmium is a niche PGM marked by extreme resource scarcity, monopolized inelastic supply, rigid high-end demand and total irreplaceability. Unlike bulk commodities, its market is driven by supply shifts, high-end industrial demand and compliance costs, with a small scale and low trading frequency, remaining a critical material for high-end industry and scientific research.
