Gelonghui, May 21丨Shenzhen Xinxing (603978.SH) said on the investor interactive platform that the current modified production line produces potassium tetrafluoroaluminate. The company uses potassium tetrafluoroaluminate as an aluminum electrolyte additive to replace aluminum fluoride. It requires downstream electrolytic aluminum companies to use their own electrolyzer to conduct industrial tests, and the cost of the electrolyzer is high. Due to economic factors, downstream electrolytic aluminum companies are more cautious about testing new technology, and large-scale promotion and application in electrolytic aluminum companies still requires a long process. The company continues to promote potassium tetrafluoroaluminate in the electrolytic aluminum industry. Currently, downstream customer trial feedback is good.
