Open-celled aluminium foam

Processing: Two-stage investment casting involves a polymer foam precursor, used to shape a mould of refractory material into which Al can be cast


Open cell aluminium foams may be useful as surfaces for catalysts or electrochemical applications. They are also used in heat exchangers.


Technique: Photography (no microscope)


Further information: Although the processing route is complicated and the product expensive, there is a high degree of control over the cell structure of such foams and the final shape can be controlled to meet near-net-shape requirements.
