Summary:

Syntactic titanium metal foam offers unique properties including high strength, low thermal conductivity and density. Powdermet fabricated syntactic titanium foams by applying metal coatings to hollow ceramic microbaloons, slurry cast and sintering these slurry cast microbaloons to form near net shape panel. These low conductivity metal foam having densities from 1/4th to 1/3 the parent metal density show a unique blend of properties suitable for cryogenic tanks , energy absorbing structures, and engineering structure application.
