Silver prices fluctuated rangebound today, while spot market premiums still showed signs of continuing to decline, and downstream transactions were still mainly concluded through substantial bargaining. In Shanghai, mainstream quotations from suppliers of domestic standard silver ingots were tentatively quoted at premiums of 600-700 yuan/kg against TD, but due to increased supply, weakening downstream consumption, and substantial bargaining, actual transaction premiums fell to 500 yuan/kg. In Shenzhen, premiums of domestic standard small silver ingots against TD dropped to 400 yuan/kg, while premiums for large ingots declined to 300-400 yuan/kg. As suppliers increased sell-offs and shipped more cargo to the Shanghai market, transaction prices in Shanghai were slightly dragged lower as a result. Some downstream consumers suspended purchases after completing post-holiday restocking, and buyers still largely stayed on the sidelines today, continuing to buy the dip through substantial bargaining. Suppliers gradually ended their efforts to hold prices firm and withhold sales, and successively adjusted prices to make shipments, while spot market transactions remained relatively sluggish.

Among precious and rare metals, osmium is a niche yet irreplaceable material, overshadowed by gold, silver, platinum and palladium but critical for high-end industry and scientific research thanks to its unique physical and chemical properties. This report breaks down osmium’s core attributes, supply, applications and market traits to unveil the “densest natural metal”. I. Basic Profile: A Distinct Platinum Group Metal Osmium (Os, atomic number 76) is a Group Ⅷ transition metal and part of the platinum group metals (PGMs), extremely scarce in nature. It has no independent deposits, only extracted and purified via platinum ore smelting alongside platinum, iridium, ruthenium, rhodium and palladium, ruling out large-scale standalone mining. Its standout properties: unmatched density (22.59g/cm³ at 20℃, higher than gold and platinum), exceptional heat resistance (melting point 3033℃, boiling point over 5000℃), and high hardness & corrosion resistance (Mohs hardness 7). It is highly brittle with poor plasticity, mostly used in powder or alloy forms. Key Safety Warning: Osmium oxidizes to toxic, volatile osmium tetroxide (OsO₄) when heated above 100℃ in air. Full-process operations (smelting, storage, transport, processing) require inert gas protection, raising production and application thresholds. II. Supply Landscape: Extreme Scarcity & Monopolized Output Osmium is far rarer than gold and platinum, with a crustal abundance of just 0.001ppm, one of the lowest stable elements globally. Proven recoverable reserves are extremely limited and highly concentrated. Global output hinges entirely on platinum mining and smelting, staying at a tiny scale: annual global production is roughly 1 ton (data from International Platinum Group Metals Association), while China’s annual output is less than 100kg. South Africa and Russia dominate global osmium resources and smelting capacity, forming a highly monopolized, inelastic supply market. Tight supply-demand balance persists, supporting strong price resilience and volatility. III. Core Applications: High-End & Irreplaceable Scenarios Despite low production and narrow application scope, osmium is a rigid material for high-precision sectors with no low-cost substitutes, focusing on four key fields: Special Hard Alloys: Osmium-based alloys excel in hardness, wear and corrosion resistance, used for high-precision bearings (luxury watches, instruments), premium pen nibs, medical scalpels and high-end mechanical wear parts. Industrial Catalysis: Osmium and its compounds act as high-efficiency catalysts for fine chemical and organic synthesis (hydrogenation, oxidation), boosting process efficiency and product purity with stable low-volume demand. Scientific Research: Toxic osmium tetroxide is an irreplaceable stain for electron microscopy samples in materials and life sciences; high-purity osmium powder serves as a specialty lab consumable. Aerospace & Military: Leveraging high density and thermal stability, osmium is used for specialty high-temperature components, precision guidance parts and high-end electrical contacts, with high added value and growing demand amid industrial upgrading. IV. Core Market Traits Osmium is a niche PGM marked by extreme resource scarcity, monopolized inelastic supply, rigid high-end demand and total irreplaceability. Unlike bulk commodities, its market is driven by supply shifts, high-end industrial demand and compliance costs, with a small scale and low trading frequency, remaining a critical material for high-end industry and scientific research.

China’s silver prices fluctuated and consolidated this week. The price spread between the Gold Exchange TD price and the SHFE March contract kept narrowing, while a large volume of imported silver ingots entered the market to meet downstream demand, driving down spot premiums for physical silver ingots rapidly. Although many suppliers were reluctant to sell and mostly held firm on offers, downstream buyers actively negotiated for lower prices, and spot premiums in China had already fallen sharply by the end of the week. As of Thursday, in the Shanghai market, the tradable quote for domestic standard silver ingots against TD premiums had been lowered to 600-700 yuan/kg. A few suppliers held firm and were reluctant to sell at premiums of 700-800 yuan/kg against TD, but actual transactions were thin. In Shenzhen, imported large ingots were processed into small ingots before entering the market for trading. Some suppliers, concerned that spot premiums would continue to fall, sold at premiums of 400-500 yuan/kg against TD. Downstream buyers actively negotiated, but remained cautious and mostly stayed on the sidelines due to concerns over further declines in both absolute prices and spot premiums. Actual procurement transactions weakened, and some downstream purchasing demand was delayed until next week. Inventory side, silver social inventory across different regions rose and fell this week. Imported large ingots or silver ingots processed from imported crude silver raw materials entered social warehouses. As downstream demand remained strong, the increase in supply only led to a slight overall buildup in silver ingot social inventory this week.

Capacity side, according to incomplete statistics, China’s alkaline electrolyzer market remained at 43.77 GW and the PEM electrolyzer market remained at 2.7 GW, with no new capacity added.

SMM News on March 11: According to SMM, the Northwest Lead and Zinc Smelter of Baiyin Nonferrous Group Co., Ltd. launched a public tender sale for about 100 mt of crude cadmium under its operation. According to the official announcement, the bidding floor price was set at a discount of 500 yuan/mt to the average SMM price, and the highest bidder after the auction won the lot. This project required at least three registrants for the auction to proceed normally. The registration deadline was 17:00 on March 16, 2026, and bidding was scheduled to begin at 10:00 on March 17, 2026. Market participants said that, as cadmium prices had shown an upward trend recently, this tender was also well worth close attention. To a certain extent, it could reflect the strength of market demand and provide some reference as to whether cadmium prices could continue to rise steadily.
