[Macro Pressures Combined With High Inventory, SHFE Aluminum Remained Under Pressure at Elevated Levels in the Short Term] Continued destocking in LME inventory provided bottom support for LME aluminum, but amid tightening fund liquidity and profit-taking by bulls, upward momentum was insufficient, and the backwardation structure weakened somewhat. In China, social inventory rose to a high for the same period in nearly five years, and the inventory buildup cycle had not ended. High inventory and weak spot fundamentals jointly weighed on upward momentum. The divergence between domestic and overseas drivers continued, the SHFE/LME price ratio kept weakening, and SHFE aluminum fell below the key threshold of 25,000 yuan/mt, remaining mainly under pressure at elevated levels in the short term.

[SMM Tin Commentary: The SHFE Tin Contract Consolidated Near the 370,000 Level, with Market Sentiment Remaining Predominantly Cautious Ahead of the Interest Rate Cut Decision]

SMM Morning Meeting Summary: Overnight, LME copper opened at $12,714.5/mt and climbed to $12,715/mt at the start of the session. Copper prices then saw the center move straight downward, before fluctuating rangebound and eventually closing at $12,340/mt, down 3.44%. Trading volume reached 33,600 lots, and open interest stood at 288,300 lots, down 4,872 lots from the previous trading day, mainly due to long position liquidation. Overnight, the most-traded SHFE copper 2605 contract opened at and touched a high of 98,000 yuan/mt, after which the center of copper prices moved straight downward to a low of 95,920 yuan/mt, then fluctuated upward and finally closed at 96,340 yuan/mt, down 2.58%. Trading volume reached 103,000 lots, and open interest stood at 198,000 lots, up 9,911 lots from the previous trading day, mainly due to increased short positions.

SMM Nickel News, March 18: Macro and Market News: (1) "Fed Chairman whisperer" Nick Timiraos said the US Fed may be more inclined to remain silent this week. But forecasts force them to sketch out a path. Two former Fed Chairmen told me they hoped to avoid forecasting interest rate cuts in the near term. Whether current officials will adopt the same stance has become the core focus of this meeting, with both hawks and doves potentially sticking to their positions by pointing to the same shock. (2) US President Trump again expressed his personal dissatisfaction with NATO at the White House on March 17 local time. Trump said whether the US should withdraw from NATO "is indeed something we should consider." Spot Market: On March 18, the SMM price of #1 refined nickel fell by 1,950 yuan/mt from the previous trading day. In terms of spot premiums, the average price of Jinchuan #1 refined nickel was 6,550 yuan/mt, unchanged from the previous trading day; the range for mainstream electrodeposited nickel brands in China was -300-400 yuan/mt. Futures Market: The most-traded SHFE nickel 2605 contract continued to fluctuate downward during the session and closed the morning session at 135,110 yuan/mt, down 1.49. Heightened geopolitical tensions in the Middle East pushed up oil prices and intensified inflation concerns. The market expects the US Fed may slow down the pace of interest rate cuts, while the US dollar continued to strengthen, creating clear pressure on nickel prices. Although macro pressure remained significant, the industrial support logic has not changed. The market is still concerned that supply of nickel intermediate products tightens. Short term, the most-traded SHFE nickel contract is expected to move sideways in the 135,000-145,000 yuan/mt range.

SMM Nickel News, March 19: Macro and Market News: (1) The US Fed kept interest rates unchanged at 3.5%-3.75%, while Governor Milan believed rates should be cut by 25 basis points. The impact of developments in the Middle East on the US economy remained uncertain. The dot plot maintained expectations for one interest rate cut in each of the next two years, but the distribution turned more hawkish. Market bets on the US Fed's rate cuts for the full year were reduced from about 20 basis points to less than 11 basis points. (2) Powell believed interest rates were at the high end of the neutral range, or slightly restrictive, leaving policy in a favorable position, and said the current situation was not stagflation. This energy supply disruption was a one-off event. Regarding whether he would remain in office, Powell stressed that he would not leave before the investigation concluded, and might not leave even after it concluded. If no successor was confirmed, he would continue to serve as acting chair. Spot Market: On March 19, the SMM price of #1 refined nickel fell by 3,100 yuan/mt from the previous trading day. In terms of spot premiums, the average price of Jinchuan #1 refined nickel was 6,750 yuan/mt, up 200 yuan/mt from the previous trading day; mainstream electrodeposited nickel brands in China were quoted at -300-400 yuan/mt. Futures Market: The most-traded SHFE nickel contract (2605) plunged sharply during the session and closed the morning session at 131,760 yuan/mt, down 2.79%. Tensions in the Middle East remained elevated, and the escalating conflict between Iran and Israel triggered market concerns over rising energy prices, intensifying inflation, and economic slowdown. Safe-haven sentiment heated up. Combined with the US Fed keeping interest rates unchanged while raising inflation expectations, expectations for interest rate cuts were revised down, causing metal prices to fall sharply across the board. Pressure from the macro perspective may continue to dominate market sentiment, and nickel prices are expected to remain in the doldrums.

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.
