- Brief description
- Open-celled aluminium foam
- Keywords
- alloy , aluminium , aluminium foam, casting, cell , composite foam, composite material , foam , investment, metal
- Categories
- Foam, Metal or alloy, Metal or alloy composite foam
- System
- Al
- Composition
- Not specified

- Reaction
- 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.
- Sample preparation
- Technique
- Photography (no microscope)
- Length bar
- 8 mm
- 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.
