Determine if aluminum is the right material for you and which alloys will work best.
Porous Mold-Quality Metapor Aluminum
- Yield Strength: Not Rated
- Hardness: Shore D80 (Soft)
- Temper: Not Rated
- Fabrication: Cast
Create molds for vacuum-forming and thermoforming applications. Metapor aluminum is porous to let air and moisture escape, which prevents bubbles and blemishes. These sheets must be milled to expose the pores; average pore diameter is 0.0006” with a total porosity of 15%.

Lightweight Aluminum Foam
- Yield Strength: See table
- Hardness: Not Rated
- Fabrication: Cast
- Specifications Met: ASTM B557, ASTM E9
Air is injected into the casting of this aluminum to reduce weight and create a crater-like appearance. These foam sheets are often used for sound insulation and architectural facades. Carbide- or diamond-tipped blades are required for machining. Diamond-tipped blades will cut this material more easily and not wear down as quickly as carbide-tipped blades.
Small-cell foam is highly dense and stiff, so it’s ideal for building high-performance acoustic panels and sturdy decorative elements with a fine, detailed texture. It’s one-sixth the weight of solid aluminum.
Large-cell foam is lightweight due to its low density. It’s one-third the weight of small-cell foam and about 5% the weight of solid aluminum. Since it allows some light through, you can use it to build architectural light diffusers. This foam has the appearance of an aluminum sponge.
