Abstract

The vehicle weight have correlation with fuel oil consumption, increasing gas emission CO2, and global warming has encouraged the development of light materials and eco-friendly environment likes aluminium foam and magnesium alloys. This aims research is to study the fabrication of aluminium foam Al-1000 with calcium carbonate as a foaming agent and the effect of magnesia-calcia ratio as stabilizer to morphology and compressive strength. In the fabrication of aluminium foam, magnesia-calcia is established to 2% weight and varying the ratio of calcia-magnesia of 0:16 ; 2:14 ; 4:12 ; 6:10 and 8:8, and calcium carbonate is required to 3% weight fraction and operation temperature is 770oC. The results show that the higher porosity is 83.23% with relative density 0.17; pore diameter is 3.97mm, pore wall thickness is 17.39 micron, rounded is 0.84 and lowest compressive strength is 3,14 MPa occurred at magnesia-calcia ration is 0:16, while the lowest porosity is 79.38% with relative density 0.21; pore diameter is 3.71; wall thickness is 101 µm and rounded is 0.84 and compressive strength is 6.611 MPa at magnesia-calcia ratio 4:12.
