    Book Review: Corrosion of Aluminium, Second Edition

    Author: Christian Vargel Publisher: Elsevier Science (2020) Review by Joseph C. Benedyk, Editor In a paradoxical sense, corrosion of aluminum should be a non-issue to many users of aluminum and its alloys, as it is normally considered to be protected by a passive oxide coating that resists corrosion under many conditions. As Christian Vargel shows […]

    Aluminum Remelting and Casthouse Strategies

    The aluminum casthouse is where aluminum wrought processing and shape casting begins, and there are many casthouse functions to consider. Scrap sorting, decoating of organic coatings on scrap, remelting, alloying, melt purification by refining and degassing, grain refining, melt transfer to casting station, casting by direct chill or other means, ingot heat treatment, and dross […]

    Welding of Aluminum Alloys

    Experienced welders will tell you that, compared to welding steel, welding aluminum and its alloys is not difficult but different. Steel, being one of the common construction materials, most welders and myself included started by learning how to weld steel. As aluminum has especially gained market share in transportation, welding aluminum is challenged in various […]

    Aluminum Casthouse Technology

     Editor’s Note: Various aspects of aluminum casthouse technology appear in almost every issue of Light Metal Age, no doubt because it is the first step and an important link in the wrought aluminum processing chain required for subsequent downstream processing and production of quality product. With no exception, the international patent survey presented here focuses […]

    Primary Aluminum: Inert Anode and Wettable Cathode Technology in Aluminum Electrolysis

    Editor’s Note: Unlike aluminum’s sustainable advantage in recycling, primary aluminum production (which uses carbon anodes in the Hall-Héroult process), continues to be energy intensive and a greenhouse gas (GHG) producer. Ignoring the effect of CO2 generation in the coal/hydrocarbon power equation, the use of carbonaceous anodes in the smelting process generates GHGs as carbon is […]
