Special alloyfoam? (Oris Horns)

Hallo!
The alloy foam is something developed for spacecraft.
I get it as foam ( like the boards on the rack) or as sandwich, with alloy plates 1 mm thick. The sandwich is very good to build cases for electronics.
The foam is good for EMV-damping, also inside enclosures.
I also used the foam, 5 mm thick to cover the outside of my BD-15 enclosures. The enclosures are rather big and can reflect a lot of sound from the midrange/tweeter. The foam helps here a lot, absoirbing ad defracting.
The boards in the rack work the same way + shielding the components from each other. Each board has a solid core for stability and also some copper-shield inside to improve conductivity.
The sandwich (15 mm thick) gives excellent shielding for electronics, is acoustical dead, avoiding microphonics.
I use this materials for years now, with very nice results.
Best regards Stephan.
