Presentation Transcript

  1. Metal Foam MEEN 3344 Ci Yang

  2. Characteristics • Made from Al, Fe, Cu, Ag, Ti, Alloy • Gas-filled pores • Very high porosity (75-95% void spaces) • Light and stiff (Strength power law density) • Similar coefficient of thermal expansion • Reduced conductivity • High cost, advanced technology aerospace and manufacturing • Open-cell & close-cell metal foams • Manufacturers: ERG Aerospace, Metal Foam Korea, M-Pore, Porvair, Metafoam Cymat Corporation, Alcoa

  3. An open-cell aluminum foam An open-cell brass foam water treatment disk A large-cell closed-cell aluminum foam A small-cell closed-cell aluminum foam

  4. Application • Light-weight structures • Biochemical implants • Filters (high-temperature filters in Chem. Ind.) • Heat exchanger • Mechanical damping devices • Sound/energy absorber • Electrodes • Sensors
