Table of Contents 1. Introduction Aluminum casting processes routinely employ fluxes—specialized salt blends that protect molten metal from oxidation and facilitate the removal of impurities. Traditionally, these fluxes have relied heavily on chlorides and fluorides, notably KCl–NaCl and KCl–MgCl₂ systems, to achieve high metal recovery and clean melt surfaces¹². However, ... Read More

1. Introduction Aluminum alloys are prized for their high strength-to-weight ratio, corrosion resistance, and conductivity. Yet, Aluminum Alloy Impurities—unintended oxide films, intermetallic particles, and trace elements—can dramatically alter these desirable properties. In melt processing, inclusions such as alumina or spinels become trapped, acting as stress concentrators that degrade tensile, yield, ... Read More

Table of Contents 1. Introduction Overhead power grids worldwide rely on aluminum conductors for their high conductivity-to-weight ratio. Over decades of service, these conductors suffer from mechanical fatigue, corrosion, creep, and thermal aging. Left unchecked, these factors raise resistance, reduce strength, and can lead to failures. Engineers use a suite ... Read More

Table of Contents 1. Introduction Hydrogen embrittlement (HE) poses a serious risk to aluminum structural rods used in demanding applications such as aerospace frames, automotive hydrogen tanks, and civil infrastructures. When atomic hydrogen penetrates the metal, it can degrade ductility and fracture resistance, leading to sudden, unexpected failures. Engineers and ... Read More

Table of Contents Introduction Aluminum wires see widespread use in outdoor power distribution due to their low weight, cost, and good conductivity. However, exposure to moisture, salts, and pollutants promotes pitting and crevice corrosion, degrading performance over time. Applying the right corrosion inhibitor can extend service life, maintain conductivity, and ... Read More
