On the other hand, the semi-solid injection-molded magnesium alloy seat frame assembly of FAW Hongqi was successfully installed, marking a key upgrade in vehicle lightweighting, with significant weight reduction achieved for each assembly. Spanning the two core fields of hydrogen storage and transportation and vehicle lightweighting, these achievements accelerated the scaled-up application of the magnesium alloy industry.

[SMM Morning Comment on Cast Aluminum Alloy: Alloy Prices Continued to Hover at Highs, While Market Demand Was Significantly Suppressed] This week, secondary aluminum alloy prices continued to rise, but the pace of demand follow-up was relatively slow. In the short term, raw material costs remained at high levels, providing strong support for ADC12 prices; however, if prices continue to rise, the suppressive effect of high prices on demand will become increasingly evident. Meanwhile, as operating rates gradually recover, there are also expectations of a mild increase on the supply side. ADC12 prices are expected to fluctuate at highs in the short term. Going forward, it is recommended to focus on the pace of downstream order release, the pressure on the market from the supply recovery process, and the impact of the Middle East situation on aluminum prices.

In the fields of precious and rare metals, compared with well-known categories such as gold, silver, and platinum-group metals, osmium has always remained a niche yet highly distinctive presence. With its unmatched physicochemical properties, it has become an indispensable key material in high-end industry and scientific research. Even though it receives limited market attention, it still possesses irreplaceable value. This article will provide a comprehensive breakdown of osmium metal, covering its basic properties, resource supply, application scenarios, and market characteristics, to offer a full understanding of this “king of density.” I. First Encounter with Osmium: A Hardcore Outlier Among the Platinum-Group Metals Osmium, with the chemical symbol Os and atomic number 76, belongs to the platinum-group metals. It is a Group VIII transition metal on the periodic table and also one of the rarest metals found in nature. As one of the six major members of the platinum-group metal family, osmium has no independent ore deposits and is commonly associated with platinum, iridium, ruthenium, rhodium, and palladium. It can only be recovered through purification during platinum ore smelting and cannot be extracted through standalone large-scale mining. This inherent characteristic directly defines its scarcity. Osmium’s physicochemical properties are truly unique in the world of metals, with highly recognizable core characteristics: first, it has the highest density in the world. Under standard conditions at 20°C, its density reaches 22.59 g/cm³, far exceeding that of gold (19.32 g/cm³) and platinum (21.45 g/cm³). It is currently the densest naturally occurring metal known, and at the same volume, it weighs far more than various conventional precious metals. Second, it demonstrates excellent high-temperature resistance, with a melting point of 3,033°C and a boiling point exceeding 5,000°C. It remains highly stable in high-temperature environments and can adapt to various industrial and scientific applications under extreme heat. Third, it has outstanding hardness and strong corrosion resistance. With a Mohs hardness of 7, it is hard, durable, and wear-resistant, and is difficult to corrode under conventional acidic or alkaline conditions. However, its drawbacks are also quite evident: it is highly brittle and has extremely poor plasticity, making it impossible to process through conventional mechanical methods, so it is mostly used in powder or alloy form. A key safety precaution must be emphasized here: when osmium metal is heated in air to above 100°C, it slowly oxidizes to form osmium tetroxide (OsO₄). This substance is highly irritating, highly volatile, and somewhat toxic. Therefore, the entire process involving osmium, including production smelting, storage and transportation, and deep processing, must be carried out under the protection of inert gas and in strict compliance with operational standards. These exceptionally high compliance and control requirements further raise the barriers to osmium’s production and application. II. Extreme Scarcity: Osmium’s Resource Endowment and Supply Landscape Osmium is far rarer than commonly recognized precious metals such as gold and platinum, and it can be regarded as a “niche treasure” in the precious metals sector. Relevant data show that the average abundance of osmium in the Earth’s crust is only about 0.001 ppm, making it one of the least abundant stable elements in the crust. Globally, identified recoverable reserves are extremely limited, and resource distribution is highly concentrated, without the formation of widely distributed ore deposits. Supply side further highlights the scarcity of osmium. As there are no standalone mines, global osmium production is entirely dependent on platinum mining and smelting, with capacity remaining at an extremely low level for many years. Global annual production is about 1 mt (data from the International Platinum Group Metals Association), while China’s annual production is less than 100 kg, with supply far below that of other platinum group metals. From the global supply landscape, traditional major platinum group metal-producing countries such as South Africa and Russia control the vast majority of the world’s osmium resources and smelting capacity. Industry supply is therefore highly monopolized, with extremely low supply elasticity. Minor changes in mine development progress, geopolitical conditions, environmental protection-related control policies, and platinum group metal smelting capacity all directly affect global osmium supply. This dual attribute of “inherent resource scarcity + constrained supply” has kept the osmium market in a long-term tight supply-demand balance and given it strong price resilience and fluctuation elasticity, securing it a unique position in the rare metals market. III. Exclusive to Cutting-Edge Applications: Core Application Scenarios for Osmium Although osmium has limited production and a relatively narrow application scope, its exceptional physical and chemical properties have enabled it to establish a precise foothold in high-end niche fields, making it an irreplaceable core material in many cutting-edge applications. Downstream demand is concentrated and highly rigid, with no low-cost substitutes currently available. Its core applications are mainly concentrated in four major areas: 1 Special Hard Alloys: Core Raw Materials for High-End Wear-Resistant Components Osmium-based alloys produced by melting osmium with metals such as iridium and platinum combine ultra-high hardness, wear resistance, and corrosion resistance, making them key materials for high-end precision instruments. These alloys are widely used in high-precision bearings for high-end watches and precision instruments, nibs for premium fountain pens, styluses for professional record players, and medical precision scalpels and wear-resistant components for high-end machinery. They can significantly extend service life and durability, making them suitable for long-term, high-load, high-wear operating environments, and they are core wear-resistant materials in high-end manufacturing. 2 Industrial Catalysis: Highly Efficient Specialized Additives for Fine Chemicals Osmium and its compounds have excellent catalytic activity and serve as specialized catalysts in certain fine chemical and organic synthesis reactions. In particular, in special chemical processes such as hydrogenation and oxidation reactions, they offer high catalytic efficiency and strong reaction selectivity, effectively optimizing process flows and improving product purity and yield. Although the unit consumption of osmium catalysts is extremely low, they are a rigid process necessity and are difficult to replace with other common metal catalysts, resulting in relatively stable downstream demand. 3 Scientific Research and Detection: Essential Specialized Consumables for Laboratories Although osmium tetroxide is toxic, it has irreplaceable value in scientific research. It is a high-quality staining agent for biological samples and microscopic material sections under electron microscopes, substantially improving sample clarity and contrast, and is an indispensable laboratory reagent in frontier research fields such as materials science and life sciences. Meanwhile, high-purity osmium powder was also widely used in high-end scientific research experiments and the R&D of specialized new materials, serving as a niche but essential consumable for major research institutes and high-end laboratories. 4. High-End Specialized Fields: Core Components for Military and Aerospace Applications Leveraging its core advantages of high density, high-temperature resistance, and high stability, osmium was also applied in specialized high-temperature components for aerospace and military applications, precision guidance components, as well as niche scenarios such as high-end electrical contacts and wear-resistant coatings. These applications were all concentrated in cutting-edge, high-precision sectors. Although the volume of each individual application was small, the product value-added was extremely high. Moreover, with the technological iteration and development of high-end manufacturing and the military and aerospace industries, related demand had the potential for steady growth. IV. Summary of the Core Characteristics of the Osmium Metal Market Overall, as a rare category among platinum group metals, osmium had highly distinctive core characteristics: extreme scarcity on the resource side, highly monopolized supply with insufficient elasticity; application-side concentration in high-precision, cutting-edge fields, with rigid and irreplaceable demand; and unique physicochemical properties, combining both advantages and application barriers. Unlike the market-driven fluctuation logic of conventional bulk commodities, the osmium market was significantly affected by factors such as supply-side changes, downstream demand from high-end industries, and compliance costs. The overall market size was small, and trading frequency was relatively low, placing it in the category of niche rare precious metals. Its core value always revolved around the two key points of “scarcity” and “irreplaceability,” making it an indispensable key metal material in high-end industrial and scientific research fields.

[SMM Magnesium Weekly Review: Magnesium Market Continued to Consolidate at High Levels, with Cost Support and Demand Stalemate Persisting] This week, the overall magnesium industry chain continued to consolidate at high levels, with prices of all categories remaining largely stable. The raw material dolomite market operated steadily, with differentiated supply across regions but overall stability, while the procurement pace on the demand side remained steady. The magnesium ingot market remained in a supply and demand stalemate, as producers showed strong reluctance to sell, and low circulating inventory supported firm quotations. However, both domestic trade and foreign trade demand appeared weak, transactions were sluggish, and FOB quotations stayed at high levels, though actual deals were limited. The magnesium powder market remained stable with a firm tone, domestic trade demand continued to recover steadily, foreign trade growth was limited, and cost support remained in place. The magnesium alloy market's benchmark price held steady, processing fees remained firm, enterprise operating rates rebounded, and downstream demand gradually recovered, though the pace of growth slowed, with overall transactions remaining mild. Looking ahead, the tug-of-war between cost support and weak demand is expected to continue, and the market may continue to consolidate at high levels.

[SMM Aluminum Morning Meeting Summary: The SHFE/LME Price Ratio Continued to Weaken, and Aluminum Prices Were Expected to Fluctuate at Highs in the Short Term] Against the backdrop of continued tightening LME liquidity, LME aluminum still had upward momentum, with strong support from overseas prices, and the backwardation structure was expected to persist in the short term. China was in a phase of high inventory + weak fundamentals, and its upward momentum was clearly weaker than that outside China. Amid diverging domestic and external drivers, the SHFE/LME price ratio was expected to continue weakening, and aluminum prices were expected to continue fluctuating at highs in the short term.

This week, ternary cathode precursor prices were broadly stable. Raw materials, nickel sulphate prices edged up today, while cobalt sulphate prices and manganese sulphate prices held steady. Discounts, for March orders, as raw material prices were expected to rise to some extent, some producers recently showed willingness to raise nickel discounts. Long-term contracts, as downstream orders remained unclear, acceptance of higher discounts did not improve significantly and was basically flat from February. Spot orders, discounts for some earlier orders had already been finalised before the Chinese New Year, while discounts for the remaining March orders rose slightly from February; production, precursor production schedules in March recovered overall from February, with some leading producers in China and producers with relatively large export orders maintaining high operating rates. Looking ahead, sulphate prices have recently remained generally firm and may provide further support for precursor prices from the cost side.
