[Market Participants Became More Rational in Sentiment, and Grain-Oriented Silicon Steel Prices May Fluctuate Rangebound Next Week] In terms of transactions, the procurement pace of end-use industries such as downstream transformers and power equipment slowed down, and purchase willingness remained cautious, with procurement mainly consisting of small-volume, as-needed restocking orders, while large-volume purchasing activity was scarce, resulting in relatively low actual market trading activity. In addition, resources from steel mills’ earlier directed orders arrived successively, and traders’ circulating inventory accumulated steadily. Some merchants offered slight price concessions to accelerate turnover and boost shipments, but the overall room for concessions remained limited and failed to effectively lift transactions.

[SMM Silicone Weekly Review: The Center of Market Transactions Shifted Slightly Lower, and Downstream Wait-and-See Sentiment Increased] This week, the quotation range for mainstream quotations in China’s silicone DMC market was 13,800-14,300 yuan/mt, down 100 yuan/mt WoW. Overall market trading sentiment remained weak, with increased back-and-forth negotiations between upstream and downstream. As raw material support still persisted, midstream players remained cautious in procurement sentiment, and wait-and-see sentiment in the market was strong.

[Weak Market Sentiment Weighed on Both Spot Silicon Metal and Polysilicon Prices]: This week, the silicon metal market moved lower after a stalemate, with weak market sentiment, some downstream procurement demand released, and cautious trading sentiment. SMM east China oxygen-blown #553 silicon stood at 9,000-9,200 yuan/mt, down 100 yuan/mt WoW. At the beginning of the week, silicon metal market prices remained in a stalemate, while the most-traded contract fluctuated around 8,550-8,750 yuan/mt, with downstream procurement mainly focused on factory cargoes. Later, affected by macro factors and capital sentiment, futures prices declined continuously and closed at 8,285 yuan/mt on Thursday. As spot-futures traders' price advantages became apparent, shipments increased, downstream procurement sentiment diverged, and the market saw transactions based on immediate needs.

[SMM Silicon-Based PV Morning Briefing] Polysilicon: The quoted price for N-type recharging polysilicon was 42-49 yuan/kg. Polysilicon prices continued to decline recently, mainly affected by wafer price cuts and market sentiment. At present, low-priced polysilicon has already fallen below the cost line of some manufacturers, and the willingness to hold quotes firm has strengthened somewhat. The upstream market was also still watching wafer price moves. Wafer: In the market, 18X wafer prices were 1.00-1.05 yuan/piece, 210RN wafer prices were 1.1-1.15 yuan/piece, and 210N wafer prices were 1.3-1.35 yuan/piece. Wafer prices remained stable. Current selling prices have already fallen below cash cost, so the likelihood of another sharp price cut was relatively small.

[SMM Cast Aluminum Alloy Morning Comment: Overnight Aluminum Futures Closed Lower, Spot Cargo Under Short-Term Pressure] On Wednesday, the ADC12 market generally showed a downward trend, with mainstream producers broadly lowering quotes by 100 yuan/mt. This price adjustment was mainly driven by the pullback in aluminum prices, which weakened cost support. Enterprises accordingly adjusted their quotes in line with market changes, but the overall magnitude of the adjustment remained relatively restrained, indicating a rather cautious market sentiment.

[SMM Cast Aluminum Alloy Morning Comment: Futures Prices Retreated After a Rapid Rise, and Market Divergence Intensified at High Levels] Overnight, the aluminum alloy 2604 contract opened higher and then fluctuated downward, opening at 23,770 yuan/mt, rising to 23,820 yuan/mt during the session, and then pulling back under pressure to a low of 23,525 yuan/mt before closing at 23,645 yuan/mt late in the session, down 80 yuan/mt from the previous settlement price, a decline of 0.34. Open interest edged up by 6 lots to 5,304 lots, with trading volume at 2,417 lots. Wait-and-see sentiment remained strong among market participants, and market divergence intensified at high levels.

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.
