China Aluminum Stocks Refresh Nearly 10-Year High, SMM Says

DISA has launched the DISAMATIC C5 vertical green-sand moulding line, designed for high efficiency and low operating cost. The system can produce 400 uncored or 340 cored moulds per hour, delivering up to 20% higher output than comparable machines while reducing maintenance needs and total cost of ownership. The company said the C5 improves casting quality, cutting grinding and rework by about 50%, and offers fast installation with compatibility for existing pattern plates. Overall, the new line enhances productivity and supports faster return on investment for foundries.

South Korea’s Ministry of SMEs and Startups, together with TIPA, has launched the “2026 Carbon Reduction R&D for Core Export Items” project, focusing on developing carbon reduction technologies for high-emission products such as aluminium and steel to address CBAM-related cost pressures. The project, open for applications in May, covers fuel substitution, process optimisation and resource recycling, with support for real-world implementation and verification. Running until 2030 with a total budget of about USD 73 million, the initiative aims to enhance SMEs’ export competitiveness under tightening global carbon regulations.

The Rio Tinto-owned Tiwai Point aluminum smelter in New Zealand faces strike risk, with 186 workers, about 28% of the workforce, planning stoppages on May 4, 6, 8 and 10. The action follows around 2.5 years of unresolved labor negotiations over pay, benefits and working conditions. The company has proposed mediation on May 20 to reach an agreement. While management said current terms remain competitive and negotiations are ongoing, the planned industrial action could disrupt production schedules and operational stability at the smelter. If talks fail to make progress, the risk of prolonged disruptions may increase, creating uncertainty for near-term aluminum supply and adding pressure to an already tight global market environment.
