Aluminium sheet is made up of various aluminum alloys. There are commercially pure aluminum grades and alloys. The pure grades are mostly used for aluminum sheet making. Aluminum is a naturally corrosion resistant element. Sachiya Steel International is one of the leading Aluminum Plate manufacturers in
1. Introduction. Aluminum is a thermally and mechanically stable soft metal, which is often alloyed to improve its other properties such as high electrical, fatigue resistance, high strength, recyclability and thermal conductivity , , .It is also known to be corrosion resistant in most environment such as mixture of phosphoric and chromic acids, gases in industrial atmosphere, Sulphur
Keywords: Aluminum alloy, corrosion mechanisms, ethylene glycol, organic, EIS 1. INTRODUCTION Al-based alloys have been the primary material in the aerospace field for many years because of their excellent mechanical behavior [1]. In particular, 5A06 aluminum alloy has
