Abstract: Aluminium foam due to its low specific weight and high stiffness to bending ratio is an adequate structural material however its compressive strength is low in comparison to its counter parts. Hence in this research work an attempt was made to enhance the compressive strength of aluminium foam which was prepared by melt route method by different addition of nickel particles. The objective of this paper is to deliver a better quality of foam, made of aluminium with low relative density and higher strength against compression. This material can be applicable where energy absorption and light weight property is heavily required such as automotive industries. Different compositions are used to find out the best conditions of producing better quality aluminium metal foam. Nickel particles were added directly to molten aluminium and different samples of 30x30x30 mm size with different percentage of nickel particles by weight were prepared. Compressive strength testing of different of these samples was performed on universal testing machine with maximum load of 400KN and pace rate of .001KN/sec. The result of compression test was compared with pure aluminium foam samples and thus the effect of percentage of nickel particles on compressive strength of aluminium foam was examined. Energy absorption of different samples of aluminium foam was also determined from stress strain diagrams generated during compression test.
