Lightweight A356 Aluminum Foam
Small Cell
Large Cell
- Yield Strength: See table
- Hardness: Not Rated
- Fabrication: Cast
- Specifications Met: ASTM B557, ASTM E9
Air is injected into the casting of this A356 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.
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%.
