China materials industry Report Interpretation

Overview

This China materials trip update summarizes meetings with companies active in cobalt, high-end copper products, glass fabrics and rare-earth magnets. Morgan Stanley emphasizes AI data centers as the strongest structural copper-demand driver, while detailing operating, supply and investment updates from Huayou Cobalt and JL Mag Rare-Earth.

Core views

The report identifies AI data centers as the strongest structural demand theme for copper. Jintian Copper expects rapid expansion of AI-related capacity through 2027, led by liquid-cooling plates and rack busbars. A next-generation AI server rack could contain roughly 1.5 tonnes of copper—about 1 tonne in cooling plates and 0.5 tonne in busbars—although processing and yield adjustment mean only about 30% of the volume ultimately enters the rack. The report says barriers in these products arise mainly from process know-how, yields and customer qualification rather than working-capital requirements. High copper prices are encouraging aluminum substitution in traditional applications. Jintian believes 2027 could be the first meaningful year for aluminum-for-copper substitution in Chinese air conditioners. At an approximately RMB80,000-per-tonne copper/aluminum price gap, the economics are becoming compelling: a theoretical 50% substitution rate could reduce copper demand by about 1 million tonnes while adding about 500kt of aluminum demand. Morgan Stanley contrasts this with AI data centers and EVs, where demand is comparatively price-insensitive. Larger and more complex cooling structures are increasing copper intensity in AI data centers, while EVs use about 120kg of copper versus only 10kg-plus for internal-combustion vehicles. China's scrap copper market could become a more important secondary supply source over time. Jintian estimates that 300-500kt of incremental domestic scrap copper could emerge annually over the next 10-15 years as installed copper stock reaches end of life. Tax and invoice distortions remain a significant obstacle to compliant supply, but rising domestic scrap availability should structurally improve China's secondary copper supply. The trip also pointed to tightening glass-fabric supply and stronger pricing in fine products. Management expects essentially no meaningful new yarn supply during 2027 except Jushi's roughly 50kt project starting toward year-end. Low-Dk, T-glass and Q-glass products have largely completed qualification and are expected to enter commercial production around end-2026. Pricing is stronger for finer products: 2116/1080 average selling prices are around RMB14-15 per metre, while 7628 pricing is up 170% year to date. For Huayou Cobalt, management discussed cost reduction, nickel operations and lithium expansion. Gypsum-based acid production lines at Huayue and Huafei are scheduled to be commissioned from year-end through the second quarter of the following year; once fully operating, they are expected to lift sulfur self-sufficiency to about 30%. Huafei is operating at half capacity and would need production to at least avoid cash losses before output resumes. Huayou produced about 100kt of HPAL nickel in 1H26 versus about 240kt in 2025, and management said drought in Indonesia had not affected nickel production. Indonesian HPAL nickel-ore prices had fallen to around US$30/wmt from a previous US$33-34/wmt high. Its RKEF projects—45ktpa Huake and 20ktpa Qingtian—were generating a small profit, with costs of about US$13,000/t of ferronickel and US$16,000/t on a nickel-equivalent basis; RKEF nickel output was about 40kt in 1H26. Huayou targets 70-80kt of lithium production in 2026 from self-supplied ores and recycling. Its Zimbabwe lithium sulfate plant has about 50kt of annual capacity and made its first commercial shipment in April 2026, making Huayou the first producer to localize lithium sulfate production in Zimbabwe. The report says the second batch of spodumene export quotas allocated to Huayou and other miners is sufficient; logistics through Durban, where growing DRC copper exports compete for capacity, are now the main bottleneck. Policy continues to favor downstream processing, making lithium sulfate structurally more attractive than concentrate exports. Huayou expects Arcadia lithium output in Zimbabwe to reach roughly 100kt next year. Its proposed Ghana greenfield lithium project remains subject to government approval and targets 50kt of lithium carbonate output in 2028, based on 1.3-1.4% spodumene grades and estimated capex of US$200-300 million. At JL Mag Rare-Earth, management expects full-year 2026 utilization above 90% of its 40kt blanks capacity, implying apparent half-on-half volume growth in 2H as EV demand enters its normal peak season. The company estimates magnet use of 1.5-2kg per EV, or about 1kg per 100kW of motor capacity; higher-power and multi-motor vehicles use more. Advanced humanoid robots can use about 3kg per unit, with lower usage for machines with fewer degrees of freedom. JL Mag is extending along the value chain through a 51% stake in Yinhai New Materials for rare-earth recycling, investments in robot companies through industrial funds, and evaluation of advanced-motor investments with potential humanoid-robot applications. It intends to maintain a high payout supported by cash flow, with full-year 2026 not below the 1H26 level. Planned 2026-27 capex of RMB400-500 million is primarily for Baotou Phase 3, which targets traditional applications and robots and may gradually ramp next year.

Analysis framework

Morgan Stanley synthesizes management commentary from China site meetings. It evaluates demand through application-level material intensity and substitution economics, supply through planned capacity, utilization and scrap availability, and company operations through production volumes, costs, project timing, logistics and capital expenditure.

Impact & implications

The report frames AI infrastructure and EVs as demand sources less exposed to copper-price substitution than traditional uses. It also suggests that domestic scrap could progressively improve China's secondary copper supply, while company-level outcomes remain tied to project execution, cost recovery, logistics and end-market demand.

Risks

• High copper prices may accelerate aluminum substitution in traditional applications, particularly Chinese air conditioners.
• Tax and invoice distortions constrain compliant scrap-copper supply.
• Durban logistics capacity is a bottleneck as DRC copper exports compete with lithium exports.
• Huayou's Ghana lithium acquisition remains subject to government approval.

What to watch

• AI-related copper capacity expansion through 2027, especially liquid-cooling plates and rack busbars.
• Whether 2027 becomes the first meaningful year for aluminum-for-copper substitution in Chinese air conditioners.
• Growth in domestic scrap-copper availability and progress in resolving compliant-supply constraints.
• Commissioning of Huayou's gypsum-based acid projects from year-end through the second quarter of the following year.
• Huayou's lithium output, Durban logistics conditions and Ghana project approval.
• JL Mag's second-half utilization, Baotou Phase 3 ramp-up and demand from EVs and humanoid robots.
