Corros affected a number of industrie loss and damages of many ma (Barbara and Robert, 2006). corrosion on aqueous enviro water, salt water and rain wat when pipes corroded with toxic environment thereby ca complications to the living sys al., 1991). Other causes can which may results in loss of equipment and alienation of and explosion etc. (Holsen et a metals are exposed to aggressiv such as, the use of acid solutio chemical and electrochemical e industrial acid cleaning, cleanin equipment, oil well acidiz descaling, they usually lead to l due to corrosion (Ating et al., al., 2017). The problem of me has received significant concer estimated that approximately 5% ABSTRACT The corrosion behaviour of al was investigated using weigh aluminium in HCl, H 3 PO 4 , H 2 SO 4 respectively.
