Значения термина metallic foams на английском

Currently the applications envisioned for metallic foams are in automobile and aircraft crumple zones, which absorb the impact of collisions, and in artificial bone.

Metallic foams are also acoustically different from typical bulk metal, and have unique electrical and thermal properties.

Metallic foams come in several types, some of which have the open structure of sponges while others contain closed cells.

Metallic foams may prove useful for planes and ships because they are lighter than solid metals and stronger than plastic.
