Synthesis of Closed Cell Aluminum Foam Using the Compression Method
This research was to study the synthesis of aluminum foam with pure aluminum and its mechanical properties. The synthesis varied at 1% - 5% of TiH2 and mixed with 99.7 % aluminum powder size of 44 µm. then compressed by hydraulic at 25, 30 and 35 tons in the diameter 27 mm, high 60 mm molded. The Aluminum foams were produced by using heat treatment at 800 °C for 10 minutes then cool to room temperature and tested its mechanical properties. The results showed that aluminum foams which lowest bulk density (0.958 g/cm3) was 2% TiH2 synthesized, compressed at 35 tons and highest bulk density (1.393 g/cm3) was 1% TiH2 synthesized, compressed at 25 tons. Moreover, the highest compressive strength (847 kg/cm2) showed at 2% TiH2 synthesized and compressed at 35 tons. Thus, this research contributes to a body of knowledge that informs the application of aluminum foam.
