SMM, March 18: The most-traded SHFE lead 2604 contract opened at 16,695 yuan/mt during the day, with prices fluctuating rangebound in the 16,665–16,720 yuan/mt range in early trading. Before noon, SHFE lead prices rose rapidly and touched a high of 16,785 yuan/mt before pulling back amid fluctuations. The tug-of-war between longs and shorts intensified, and prices remained rangebound within 16,610–16,680 yuan/mt before closing at 16,645 yuan/mt, posting a small bullish candlestick, up 45 yuan/mt, or 0.27%. At present, lead prices have stopped falling and rebounded, gradually returning to being driven by fundamentals. On the supply side, ex-works inventory at primary lead smelters continued to be digested, and some suppliers held prices firm in spot lead shipments, providing relatively strong spot support; willingness to sell among secondary lead suppliers diverged, and most enterprises became more reluctant to sell due to losses combined with bullish expectations, leading to a continued contraction in effective market supply. On the demand side, orders from downstream battery plants increased, and production remained at full capacity, providing positive support for lead prices. However, social inventory of lead ingot is still on an upward trend. In addition, as more smelters resume production in mid-to-late March and capacity is gradually released, market circulation will further increase, and lead prices are expected to have limited upward momentum.

[Shanghai Spot Copper] Intraday trading in the spot market improved somewhat from yesterday. Suppliers still showed willingness to hold prices firm, but some suppliers’ sell-offs temporarily weighed on the market, causing spot premiums to decline somewhat in the second trading session. Coupled with the narrowing Contango price spread between nearby futures contracts, suppliers’ willingness to ship to delivery warehouses weakened somewhat, and spot premiums remained under pressure. Demand side, as copper prices fell, downstream enterprises may have had some restocking demand, but the current copper prices had limited actual appeal. Supply side, social inventory remained at a high level, but spot cargo available for actual circulation was relatively tight. Some warrants were already seen flowing out during the day, which may ease some pressure on spot supply. Meanwhile, the import window remained open, and expectations for subsequent inflows of cargo from outside China increased. Overall, amid the tug-of-war between sellers and buyers, Shanghai spot copper is expected to maintain the current discount structure overall tomorrow.

[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 News, March 16: Data Brief: As of Monday, March 16, copper inventories in SMM’s major regions nationwide fell 5.46% WoW from the previous Monday, with destocking seen across all regions. Specifically, in Shanghai, arrivals of imported and domestic supplies were normal, while downstream consumption continued to recover, leading to some inventory drawdown; in Jiangsu, inventory declined slightly, supported by recovering downstream consumption; in Guangdong, consumption continued to improve, arrivals remained normal, and inventories likewise maintained a destocking trend. Looking ahead, arrivals of imported and domestic supplies are expected to remain stable, with overall supply stabilizing; demand side, the pullback in copper prices effectively stimulated downstream consumption, and rigid demand is gradually being released. According to the survey, the weekly operating rate of copper cathode rod is expected to rise to 79.19% this week, up 6.27 percentage points WoW. Taking both supply and demand into account, the market is currently showing a pattern of “stabilizing supply and recovering consumption,” and social inventory is expected to continue destocking this week.

During the survey period (March 10–March 16), the capacity utilization rate of rebar and wire rod rolling lines in the Central China region increased to varying degrees.

[SMM Stainless Steel Daily Review] SS Futures Fluctuated, Rising First and Then Falling, While Spot Quotes Edged Lower and Transactions Recovered SMM News, March 17: SS futures moved sideways. During the day, SS futures rose first and then fell, overall maintaining a sideways movement pattern, and closed at 14,155 yuan/mt by the midday break. In the spot market, although SS futures were relatively strong in the morning, affected by the previous cuts in guidance prices by major stainless steel mills, trader quotes still edged slightly lower than yesterday.

As the traditional peak consumption season of "Golden March and Silver April" began, the stainless steel market entered a window for demand recovery, with downstream end-users gradually recovering. Recently, activity in inquiries and purchases increased markedly, but stainless steel spot prices overall remained basically stable, with no obvious fluctuations. End-user procurement was still mainly driven by rigid demand, and the full bustle of the peak season had yet to emerge, ...
