Silicon metal prices to swing up
----Interview with Dequan Zhang

Silicon Metal Marketing Director
Zhejiang Wynca Chemical Group Co., Ltd.
Zhejiang Wynca Chemical Group Co., Ltd. was founded in 1965 and successfully listed on the stock exchange in 2001 (Stock Code: 600596). Headquartered in Jiande, Hangzhou, the company operates over 80 wholly-owned subsidiaries. Wynca’s core business spans three main areas: crop protection, silicon-based new materials, and new energy materials. In the field of silicon-based new materials, Wynca has established a fully integrated industrial chain covering silicon ore mining, silicon metal production, silicon powder processing, and organosilicon monomer synthesis.
Asian Metal: Welcome, Mr. Zhang, and thank you for joining us today. Could you please begin by briefly introducing your company?
Mr. Zhang: Zhejiang Wynca Chemical Group Co., Ltd. was founded in 1965 and became publicly listed in 2001 (Stock Code: 600596). Our headquarters is located in Jiande, Hangzhou, and we currently operate more than 80 wholly-owned subsidiaries. Our core business encompasses three primary sectors: crop protection, silicon-based new materials, and new energy materials. Within silicon-based new materials, we have developed a comprehensive industrial chain—from silicon ore mining and silicon metal production to silicon powder processing and the synthesis of organosilicon monomers. We also manufacture downstream products such as silicone rubber, silicone oil, and silane coupling agents. Currently, we hold quartz ore reserves of approximately 120 million tons, possess an annual silicon metal production capacity of 250,000 tons, and a silicon powder capacity of 300,000 tons. Our yearly production capacity for silicone monomers has reached 500,000 tons.


Asian Metal: We’ve observed that the operating rate of silicon metal producers in South China was relatively low in early June compared to the same period last year, despite the rainy season. What are the reasons behind this?
Mr. Zhang: This has indeed been a concern across the industry. The core issue lies in persistently low market prices. Since the second half of 2024, demand from the polysilicon sector has continued to decline, while supply has remained high. This imbalance has led to an oversupplied market and high inventory levels. While the combined monthly demand for silicon metal from the polysilicon, organosilicon, and aluminum alloy sectors is about 350,000 tons, total plant and spot market inventory has surged to 1.2 million tons. As a result, prices have fallen to historic lows. By late July, the price of 421-grade silicon metal had declined to approximately RMB 8,500/t (USD1,186/t), while production costs—even during the rainy season—remained around RMB 10,000/t (USD 1,396/t) in Southwest China. Under such circumstances, where “production equals loss,” many producers are reluctant to resume operations.
Asian Metal: What is your current annual capacity for organosilicon monomers, and what is the recent operating rate? How do you see this evolving in the second half of the year?
Mr. Zhang: Wynca’s annual production capacity for silicone monomers stands at around 500,000 tons. Thanks to our fully integrated downstream industrial chain, our operating rate remained high throughout the first half of the year. Recently, the price of silicon metal has rebounded, and a major facility accident further tightened supply, pushing up silicone product prices. We anticipate that the operating rate across the industry will remain stable in the second half of the year, with a limited likelihood of any significant price declines.


Asian Metal: How would you assess the current demand for silicon metal from the polysilicon and aluminum alloy sectors?
Mr. Zhang: Demand from the polysilicon sector remains weak at present. Although some major producers have plans to ramp up output during the rainy season, the overall operating rate hovers around 35%, mainly due to subdued demand from the photovoltaic industry and ongoing industry-wide self-regulation. On the other hand, the operating rate among aluminum alloy producers has remained relatively stable. We are approaching the end of the traditional peak season for aluminum ingot consumption. Meanwhile, the recent listing of aluminum alloy ingots on the commodities exchange has attracted more attention and may inject renewed vitality into the market. We foresee a moderate uptick in aluminum alloy production going forward.
Asian Metal: What is your outlook for the price trend of silicon metal in China in Q3?
Mr. Zhang: The recent rebound in prices has been driven by multiple factors. These include government policies aimed at curbing “malicious internal competition” and eliminating outdated capacity in the non-ferrous metals sector, which have significantly boosted market confidence. At the same time, speculative capital has flowed into the financial market, fueling further price increases. In addition, major producers in Northwest China have reduced output, offsetting the increased production from Southwest China during the rainy season. The extent of this supply reduction exceeded market expectations and accelerated the price rebound. However, real demand in the spot market has not yet recovered. Most buyers are still purchasing on a need-only basis or drawing from existing inventories, maintaining a cautious, wait-and-see stance.
