Semi-productions and Articles of Foamed Aluminum produced by a Powder Metallurgy Technique

摘要

VILS Stock Co has developed a pilot technology for production of sheet size 5-30 x 1000 x 1000 mm , and granules of 5-15 mm in diameter foamed aluminum semiproducts and artickes by a powder metallurgy technique. The material produced was comprehensively studied depending on parameters of their production. Mechanical properties, acoustical absorptivity, moisture absorptivity, combustibility, impact energy absorption and a number of other properties has been investigated. This material used for production of the screen acoustical.
