Securities Star reports that, according to data from the Tianyancha APP, Jiangfeng Electronics (300666) has recently obtained a patent authorization for an invention titled “A Preparation Method for Ultra-Pure CuAl Alloy,” with the patent application number CN202310860172.5, and the authorization date set for March 24, 2026.

Patent abstract: The invention provides a preparation method for ultra-pure CuAl alloy, which includes the following steps: preparing alloy ingot raw materials, where the center of the alloy ingot raw material is aluminum, and copper is coated on the outer side of the aluminum; placing electrolytic copper and the resulting alloy ingot raw materials into a graphite crucible for vacuum induction melting, yielding ultra-pure CuAl alloy. The preparation method for ultra-pure CuAl alloy provided by this invention effectively avoids direct contact between aluminum and the graphite crucible during melting, which would introduce carbon particles into the alloy, and prevents aluminum burn-off that could lead to alloy composition not meeting requirements, thus improving the purity and quality of the alloy to meet the demands for high-quality targets.

So far this year, Jiangfeng Electronics has obtained 33 new patent authorizations, an increase of 83.33% compared to the same period last year. According to the company’s mid-year financial data for 2025, the company invested 119 million yuan in research and development in the first half of 2025, an increase of 16.82% year-on-year.

Through big data analysis from Tianyancha, Ningbo Jiangfeng Electronic Materials Co., Ltd. has invested in a total of 52 enterprises and participated in 69 bidding projects; regarding asset clues, there is 1 trademark information, 1,898 patent information, and 13 copyright information; in addition, the company also holds 21 administrative licenses.
