Dual Fluctuations in Copper and Magnetic Core Prices: Lianheng Electronics Navigates Pressures for Opportunities

2026-01-06

On Jan 6, 2026, China’s copper prices soared sharply, with Shanghai copper futures closing at 105,320 yuan/ton (up 4.88%) and spot prices surging over 3,000 yuan/ton to a record high. Meanwhile, the magnetic core market saw structural adjustments, with high-performance products gaining share and leading firms’ price moves triggering industry ripples. As copper accounts for 30%-50% of its product costs, Lianheng Electronics (a transformer and inductor maker) is pressured. It may leverage the "magnetic-for-copper" trend, optimize designs via non-standard customization to cut copper reliance and seek transformation opportunities, drawing market attention to its follow-up moves.
