The naturally occurring bio hazardous material Egg Shell is added to the aluminum 6061 grade alloy powder and its effects on the micro structures and the properties of the composite Al 6061 with egg shell were studied. The samples of 5, 10, and 15 % by weight of the egg shell in the Al 6061 alloy powder were prepared and studied in by an optical microscope. The properties both physical and mechanical including density and Vicker's micro hardness are estimated. The results showed an improvement of hardness of about 14% with the improvement in the percentage of reinforcement. The SEM images of the specimens showed a good bonding between the egg shell and the Al 6061 alloy powder. The density of the composite reduced significantly with an increase in the composition of the egg shell in the composite. © 2014 Published by Elsevier Ltd.
