About apheros
apheros is a technology start-up founded in 2023 and based in Baden in the Swiss canton of Aargau. The company develops and manufactures patented metal foams with ultra-high surface area and a fully open pore structure, as well as cold plates based on these foams for direct-to-chip liquid cooling. The company's own foaming process starts from a water-based metal powder suspension that is controllably foamed, cast into molds and thermally treated. The metal foams achieve porosity of 65 to 90 percent, pore densities up to 350 PPI and densities of 0.9 to 2.2 g/cm³; metal composition, porosity and pore size can be adjusted without retooling. Copper, nickel, iron, stainless steel and further alloys on request are processed. Target industries include data centers and AI high-performance computing, green hydrogen production, energy storage, catalysis and high-temperature filtration.
