Cymat A35620SC 040SS Stabilized Aluminum Foam
Categories:	Metal; Metal Foam, Mesh, or Honeycomb; Metal Matrix Composite; Nonferrous Metal; Aluminum Alloy; Other Engineering Material; Composite Core Material
Material Notes:	Description: Cymat A35620SC 040SS stabilized aluminum foam (SAF) is a closed cell aluminum foam formed from A356 aluminum alloy with a density of 0.4 g/cm³. The mechanical properties of SAF make it ideal for many varied applications. These properties include: High strength and stiffness to-weight ratio Strain rate insensitive (the speed of loading does not affect the strength) Notch insensitive (holes do not affect material strength) Constant properties over time, temperature and moisture range High mechanical energy absorption in all directions Not flammable or susceptible to environmental degradation Acoustic and thermal insulation properties Electromagnetic insulation properties Recyclable Applications: Energy absorption for vehicle crashworthiness Energy absorption for blast protection Structural stability Core for a casting Information provided by Cymat.
