ABSTRACT

        Metallic cellular structures based on metallic hollow spheres (MHS) are a new highly
porous material. Single metal hollow spheres can be made with very good dimensional
control due to the high performance of the manufacturing process. Hollow spheres structures
can be realized by resin bonding, soldering and sintering of single spheres. This reveals a
wide spectrum of different properties and possible applications. In this contribution we would
like to focus on mechanical and acoustic properties. Mechanical tests have been carried out
on single MHS and MHS-structures. Sintered MHS-structures were tested in exhaust systems
and the results will be presented and discussed. Further applications are introduced and
discussed.
