An improved process of degassing of molten Aluminium which comprises (i) placing graphite crucible in a furnace and preheating at temperature in the range between 750-800°C, (ii) charging aluminium pieces into the preheated crucible and allowing the aluminium to melt fully, at temperature in the range between 750-800°C, (iii) dipping electrodes in the above aluminium melt in such a way that one electrode immersed fully in the molten bath and other electrode just touches the upper part of the melt, (iv) passing current through the molten aluminium bath in the range of 3-5A for a period ranging between 5-15 min and maintaining temperature in the range between 750-800°C, (v) casting the molten aluminium in the conventional method.
