The aim of this research was to develop marine grade aluminium (Al-3%Mg) matrix composite resistant to stress corrosion cracking (SCC). Silicon carbide particulate (SiCp) was used as reinforcement at 5% interval from 0- 25%. Sodium chloride (3.5% NaCl) was used as marine environment. The materials were developed through stir casting process. Slow stain rate testing (SSRT) machine was used for the study of the SCC in 3.5% NaCl. The XRF analysis conducted on the materials proved that the elements were within the scope. Microstructural analysis of the materials showed a clear evidence of dendritic formation of the alloy matrix coupled with the SiCp reinforcement. SCC test showed that control sample A failed at a lower energy of 12.3KN with an extension of 0.7472 mm while Sample F recorded the highest value of energy up to 20 KN with an extension of 1.829 mm. The developed composite materials were found to be more reliable for use in marine environment than the existing marine grade alloy presently in use in most of the facilities in marine environment. It was learned that with little improvement on the existing marine grade Al alloy a lot of life and resources will be saved.
