Aluminum Foam

Large Cell |
Injected with air during casting, aluminum foam is even lighter than solid aluminum and has a crater-like appearance. It’s often installed as sound insulation and on the exterior of buildings.
To machine aluminum foam, you’ll need a carbide- or diamond-tipped blade. Diamond blades cut more easily and last longer than carbide ones.
Large Cell—Our lightest aluminum foam due to its low density. It's 1/3 the weight of small-cell foam and 1/20 the weight of solid aluminum. Since light peeks through the holes, it's often used to build architectural light diffusers.
