New Windfall for Asia-Pacific Casting: Data Center Cooling Demand Spurs R&D of High-End Aluminum Alloys
On July 28, 2026, Bangkok—Against the backdrop of explosive global AI computing demand, the Asia-Pacific casting market received another blockbuster announcement. The Thai Foundry Association and the Japan Casting Technology Research Center formally signed a joint R&D agreement today to develop a new high thermal conductivity cast aluminum alloy, specifically for key heat dissipation components in data center liquid cooling systems. This move not only marks a substantive step for the Asia-Pacific foundry industry into high-end applications but also signals that traditional casting is accelerating its transformation toward higher added value and technical sophistication.
Cooperation Details: From Material Formulation to Mass Production Process
According to a joint statement, the collaboration will focus on optimizing aluminum alloy composition, precision casting processes, and technical validation for large-scale production. The Japan Casting Technology Research Center will provide its cutting-edge expertise in aluminum matrix composites, while the Thai Foundry Association leverages its mature aluminum die-casting supply chain and Southeast Asia's geographic advantages to enable rapid technology transfer from lab to factory. The initial phase plans to invest 1.2 billion Thai baht (approximately US$34 million), aiming to launch a commercial-grade high thermal conductivity aluminum alloy grade by the end of 2027, with a thermal conductivity exceeding 250 W/(m·K)—nearly double that of traditional cast aluminum alloys.
“Data center cooling systems impose extremely high requirements on material thermal conductivity, fatigue resistance, and cost control,” said Charoen Sirisopha, President of the Thai Foundry Association, at the signing ceremony. “Collaboration with our Japanese partner will help Thai foundries break out of low-end homogeneous competition and enter the supply chains of global tech giants.” Kenichi Yamamoto, Director of the Japan Casting Technology Research Center, emphasized, “This is a model of technical complementarity between the foundry industries of Japan and Thailand. Together we will define the industry standards for next-generation heat dissipation materials.”
Market Background: AI Computing Explosion Drives Surge in Heat Dissipation Material Demand
As a core region for global data center construction, the Asia-Pacific saw a 40% year-over-year increase in new server power density in the first half of 2026. Traditional air cooling can no longer meet cooling demands, with liquid cooling penetration exceeding 30%. This directly triggered market explosion for high thermal conductivity metal materials. According to the latest MarketsandMarkets report, the global data center thermal management materials market is expected to grow from US$7.2 billion in 2025 to US$19 billion by 2030, with aluminum alloy cold plates, liquid cooling pipes, and other cast components taking the largest share.
Currently, the industry mainly uses copper or copper alloys for heat dissipation, but copper suffers from high density, high cost, and casting difficulties. Aluminum alloys become the preferred alternative due to lightweight, low cost, and easy formability, but ordinary aluminum alloys have a thermal conductivity of only 110-150 W/(m·K), far below copper's 400 W/(m·K). Therefore, developing aluminum alloys that combine high thermal conductivity with good castability has become a global focus for materials scientists. The Thai-Japanese cooperation targets precisely this technical "pain point."
Industry Impact: Asia-Pacific Casting Landscape May Be Reshaped
For a long time, the Asia-Pacific casting market has been dominated by traditional fields such as automotive parts and building hardware, with profit margins narrowing. The Thai-Japanese move into high-end data center heat dissipation components is expected to lead the transformation and upgrade of the entire Asia-Pacific casting industry. As one of Southeast Asia's largest aluminum die-casting bases, Thailand boasts a complete supply chain and low production costs. Successfully entering the supply chains of tech giants would generate significant demonstration effects.
“This is not only a technical cooperation but also a milestone for the casting industry transitioning from traditional manufacturing to advanced materials,” commented Li Wei, researcher at the Institute of Metal Research, Chinese Academy of Sciences. “In the future, competitiveness of foundry companies will no longer depend on tonnage and scale, but on material innovation and precision.” He also noted that Chinese foundry companies have already made inroads into high thermal conductivity aluminum alloys, such as an Al-40Si alloy from a Suzhou company achieving 200 W/(m·K), currently under validation with several server manufacturers. The technology race in the Asia-Pacific has already begun.

Technical Route: Why Choose Casting Over Forging or 3D Printing?
In heat dissipation material manufacturing, casting offers unparalleled advantages: ability to form complex internal flow channel structures (e.g., microchannels in liquid cooling plates), suitability for high-volume production, and low overall cost. While forging provides higher strength, it struggles with complex internal features; 3D printing is flexible for small-batch customization but cannot compete on efficiency and cost. Hence, high thermal conductivity cast aluminum alloys are regarded as the optimal solution for scalable liquid cooling components.
The core breakthrough of this Thai-Japanese collaboration lies in resolving the trade-off between thermal conductivity and fluidity. Traditional methods to improve thermal conductivity (adding silicon, copper, etc.) reduce casting fluidity, causing filling difficulties for thin-walled parts. The Japanese team successfully balanced thermal conductivity and castability by introducing trace rare earth elements and optimizing heat treatment processes. The Thai Foundry Association will develop process parameters adapted to local equipment conditions to ensure high production yield.
Supply Chain Restructuring: Southeast Asia May Become Global Data Center Heat Dissipation Manufacturing Hub
As global tech giants accelerate data center construction in Malaysia, Thailand, Indonesia, and beyond, supply chain localization is increasingly evident. Traditional heat dissipation components are mainly manufactured in China's Yangtze River Delta and Pearl River Delta, but geopolitical risks and rising costs drive manufacturers to diversify. Thailand, with stable electricity supply, low labor costs, and favorable trade relations with China and Japan, is becoming a prime destination for heat dissipation capacity relocation.
Data from the Thailand Board of Investment (BOI) shows that foreign investment project applications involving data center heat dissipation components surged 210% year-over-year in the first half of 2026. Implementation of this Thai-Japanese casting cooperation project will further solidify Thailand's position in high-end casting and radiate across the ASEAN region. It is estimated that by 2028, Southeast Asia's cast heat dissipation component capacity will account for 25% of the global total, double the current level.
