LK TECH (00558) surged over 13% in late trading. As of press time, the stock was up 10.33% to HK$5.98 with trading volume reaching HK$646 million.

On the news front, LK TECH recently signed a strategic cooperation agreement with four companies specializing in magnesium alloy and humanoid robot development, officially launching a joint R&D project for magnesium alloy humanoid robots. The project aims to break through traditional bottlenecks in robot weight and strength, achieving a dual revolution in structural lightweighting and manufacturing efficiency. Additionally, the five parties will jointly establish a "Humanoid Robot Body Component Joint R&D Center" to focus on overcoming core technical challenges including magnesium alloy shell forming, process optimization, and lightweight structural design.

Zhongtai Securities noted that lightweighting is crucial for robot endurance and motion response speed, with magnesium-aluminum alloys becoming ideal materials for robot lightweighting due to their low density and excellent strength properties. Everbright Securities also pointed out that lightweighting has become an irreversible development path for the automotive industry. Magnesium alloys, as important materials for automotive lightweighting, offer significant advantages in electric drive systems. Meanwhile, demand for magnesium alloys in the humanoid robot sector continues to expand, with semi-solid magnesium alloy injection molding machines expected to open new incremental growth opportunities for companies.
