About 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%.

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.
