[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.

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.

[SMM Coking Coal and Coke Daily Brief Review] In terms of supply, coking costs increased and losses widened somewhat. At present, coke producers were barely maintaining normal operating rates, while coke production remained temporarily stable. Meanwhile, downstream demand for coke increased, and coke producers' shipments improved somewhat. On the demand side, steel mills were in an active phase of resuming production, while finished steel prices fluctuated upward and steel mill profitability improved somewhat, boosting production enthusiasm and increasing demand for coke. In summary, the fundamentals of coke supply and demand developed in a positive direction, and the coke market may remain generally stable with slight rise in the short term.

SMM, March 18: The SHFE aluminum 04 contract moved lower today. Affected by the decline in aluminum prices, overall purchase sentiment rose today. Sellers held prices firm, with mainstream quotations and transaction prices in the market mostly ranging from the average price to +10 yuan/mt. Today, the east China market shipment sentiment index was 3.17, up 0.05 MoM; the buying sentiment index was 3.03, up 0.33 MoM. Today, SHFE aluminum futures prices pulled back, and buying sentiment in the central China market surged. Bullish sentiment in the market was strong, and willingness to buy the dip was significant. Meanwhile, suppliers tended to hold back from selling and turned to purchasing at lower prices to profit from the price spread. Only some trading firms engaging in both spot and futures market took profits on premiums and shipped goods, while the overall reluctance to sell was evident. Market quotations ranged from parity with the central China price to a premium of 60 yuan, but final actual transactions were mainly concentrated at premiums of 30-40 yuan over the central China price. Today, the central China market shipment sentiment index was 2.59, down 0.01 MoM; the buying sentiment index was 2.42, up 0.04 MoM. Inventory side, aluminum ingot inventory in major consumption regions increased 8,500 mt MoM today, with the inventory buildup mainly coming from Guangdong. In the short term, aluminum ingot inventory continued its seasonal buildup after the Chinese New Year. Affected by bullish market sentiment, premiums were expected to remain on a narrowing trend.
