Alloy Enterprises manufactures aluminum components through a rapid fabrication process using semisolid diffusion to create complex parts like cold plates with internal channels, heatsinks, chillers, brackets, and connectors. The semisolid diffusion method produces parts without specialized molds, reducing material use and enabling fast prototyping and production across multiple versions of product families for mass customization. Compared with traditional methods, the process lowers costs, minimizes waste, and speeds turnaround while supporting high-volume production and reshoring. The goal is to provide high-quality, affordable aluminum components at scale to shorten development cycles and ensure steady supply for customers in thermal management and related industries.

Johnson Controls to acquire Alloy Enterprises, boosting data center cooling efficiency by up to 35%

Johnson Controls has signed an agreement to acquire Alloy Enterprises, a Boston-based thermal management technology company, to strengthen its position in the data centre cooling market. Financial terms were not disclosed. Founded in 2020, Alloy Enterprises specialises in advanced direct liquid cooling components that can improve thermal management efficiency by up to 35% and reduce pressure drop by up to 75%, resulting in lower overall cooling system energy use. The company's proprietary Stack Forging manufacturing process creates single-piece components with embedded microgeometries for maximum heat transfer. The acquisition complements Johnson Controls' existing thermal management portfolio and aligns with its strategy to deliver differentiated cooling solutions for AI-driven data centres. The transaction is expected to close in fiscal Q3, subject to regulatory approvals.
