Compare over 20 aluminum alloys to find the right material for you—all with material certificates for traceability.

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%.
