Aluminium based matrix composites remain the most explored metal matrix material for the development of metal matrix composites. The present work deals with the fabrication of aluminium-6069 alloy metal matrix composites (MMCs) reinforced with molybdenum and coconut shell. The specimens were prepared by taking into consideration of six different weight fractions of aluminium 6069, molybdenum powder and coconut shell ash by stir casting method. The first three specimens were prepared in such a manner that aluminium 6069 and coconut shell ash weight fraction varies by 2% and molybdenum powder weight fraction kept constant by 1%. The next three specimens were prepared in the same manner, coconut shell kept constant by 1%, molybdenum powder and aluminium 6069 varies by 2%. The main purpose of the paper is to study the properties of Aluminium-6069 alloy reinforced with molybdenum and coconut shell ash composites fabricated by stir casting technique and Tensile test was performed by using equipment’s such as Universal testing machine. Based on the results obtained, the tensile strength was improved by adding coconut shell ash particles and molybdenum to aluminum-6069 alloy.
