As the global race to build faster and more powerful AI systems intensifies, one challenge looms large, heat. Data centers are becoming energy-hungry behemoths, and keeping them cool is turning into one of the toughest engineering puzzles of this decade. A Boston-based startup, Alloy Enterprises<\/strong>, believes it has found a breakthrough.<\/p>\n\n\n\n

When Nvidia unveiled its upcoming Rubin GPU series in March, the tech world took notice, not just for its performance, but for its power draw. The Ultra version, expected in 2027, could consume as much as 600 kilowatts per rack<\/strong>, nearly double what high-end EV chargers can deliver. That level of energy means enormous heat output, and traditional cooling systems can\u2019t keep up.<\/p>\n\n\n\n

The Metal Solution to a Hot Problem<\/h2>\n\n\n\n

Alloy Enterprises<\/a> has created a novel manufacturing process that transforms sheets of copper into solid cooling plates<\/strong>. These plates aren\u2019t just for GPUs, they also manage the heat from supporting components like memory and networking chips, which make up around 20% of a server\u2019s cooling needs.<\/p>\n\n\n\n

\u201cWhen racks were pulling 120 kilowatts, we didn\u2019t worry much about that 20%,\u201d said Ali Forsyth<\/strong>, the company\u2019s co-founder and CEO. \u201cBut as we approach 600 kilowatts, everything needs liquid cooling, even parts like RAM and networking chips.\u201d<\/p>\n\n\n\n

Unlike traditional machining or 3D printing, Alloy\u2019s technique, called stack forging<\/strong>, bonds layers of metal together using a mix of heat and pressure<\/strong>. The process yields a seamless, solid metal plate capable of handling high liquid-cooling pressures without leaks.<\/p>\n\n\n\n

How Stack Forging Outperforms the Old Way<\/h2>\n\n\n\n

Conventional cold plates are made by machining two halves and then sintering them together, a method that often creates seams prone to leaks. Alloy\u2019s diffusion bonding process eliminates those weak points, creating a one-piece structure.<\/p>\n\n\n\n

Stack forging also allows for ultra-small internal features, as tiny as 50 microns<\/strong>, about half the width of a human hair. This enables more efficient coolant flow, resulting in 35% better thermal performance<\/strong> compared to competing solutions.<\/p>\n\n\n\n

Precision Engineering Meets Software<\/h2>\n\n\n\n

Alloy\u2019s production process begins with rolls of copper<\/strong>, which are laser-cut and coated with a bonding inhibitor on areas that shouldn\u2019t fuse. The slices are then perfectly aligned and pressed under intense heat and pressure, producing a single, seamless block of metal.<\/p>\n\n\n\n

Customers provide key dimensions, while Alloy\u2019s proprietary software helps design plates optimized for its unique process. The startup originally worked with aluminum but transitioned to copper after rising interest from data center operators seeking superior heat conduction and corrosion resistance.<\/p>\n\n\n\n

A Quiet Power Behind the Scenes<\/h2>\n\n\n\n

While Forsyth declined to name clients, she hinted that Alloy Enterprises is already collaborating with \u201call the big names<\/strong>\u201d in the data center industry. After officially unveiling its copper cold plates in June, the response was overwhelming.<\/p>\n\n\n\n

As AI infrastructure grows in complexity and energy demand, Alloy Enterprises\u2019 innovative metal stacking technology<\/strong> could play a pivotal role in keeping the next generation of supercomputers from overheating, and in doing so, may quietly help sustain the future of AI itself.<\/p>","protected":false},"excerpt":{"rendered":"
