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

Applications: 

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.
