Tungsten hexafluoride is a key deposition material in the manufacturing of memory chips and advanced logic chips, and it has been a popular product in the current surge in demand for electronic specialty gases. Affected by factors such as the exit of some ex-China capacity and continuous capacity expansion of downstream memory chips, the supply-demand gap has widened, directly pushing product prices into an upward trajectory. An analyst said: "Taking tungsten hexafluoride, which has seen a significant market price increase, as an example, the average monthly price of 5N-grade in June is expected to reach 1,760 yuan/kg, up 236% YoY. The surging demand for memory chips has been the core underpinning throughout." The head of a specialty gas producer in Shanghai said that demand for helium had climbed sharply recently and that, despite running double shifts, the plant’s production still could not meet demand. The head noted: "The semiconductor industry has very high demand for helium. Many clients are asking—prices change daily. It's possible that the price you pay today won't be available tomorrow, or you simply can't buy it.

Magnesium Ingot Weekly Price Rose, Upstream Support Strong, Downstream Follow-up Insufficient, Upside Room Limited [SMM Magnesium Weekly Data]

[Weekly Magnesium Ingot Prices Rise on Strong Upstream Support; Insufficient Downstream Follow-Through Limits Upside Room] This week, mainstream quotations for magnesium ingot in major producing areas were 15,900-16,000 yuan/mt, up 100 yuan/mt WoW, with FOB prices at $2,250-2,350/mt. This round of magnesium ingot price gains was driven by three factors: supply-side maintenance-related production cuts, cost push from coal and ferrosilicon, and concentrated delivery and restocking by traders. However, after the price increase, downstream fear of high prices emerged and transactions returned to mediocre levels; foreign trade remained weak, constrained by exchange rate fluctuations and the uncertain recovery of summer break orders. Upstream dolomite prices were stable, with sufficient supply from multiple channels; downstream magnesium powder and magnesium alloy prices followed the increase, but demand follow-through was insufficient. Magnesium alloy processing fees remained under pressure due to ample inventory, the impact of non-standard supply sources, high-temperature maintenance at die-casting enterprises, plastic substitution in two-wheelers, and other factors. In the short term, cost support is pitted against weak demand, and magnesium prices continue to move sideways.

AMPRO to Establish Titanium Excellence Center in New York, Boosting Aerospace-Grade Recycled Titanium Supply

[SMM Titanium Flash] On August 13th, according to foreign media reports, AMPRO announced its plan to establish a Titanium Excellence Center in New York State, USA, to enhance its supply capability of aerospace-grade recycled titanium. The center will operate as a part of ELG Utica Alloys, adjacent to its Hekimo factory, and is scheduled to be fully operational by January 2027. AMPRO stated that this move aims to meet the growing demand for recycled titanium in the aerospace industry and improve production efficiency and shorten delivery cycles through advanced automation technology. With the continuous improvement of the recycled titanium supply chain, the sustainable supply capability of aerospace-grade titanium is expected to be further enhanced.
