Metallurg Aluminium’s ALTAB™ alloying tablets are used in casthouses world-wide for the manufacture of high-quality aluminium alloys in applications such as rolling ingot for foilstock and canstock, billet for precision extrusions and high-quality foundry casting alloys. For the precise compositional adjustment of alloy melts or for bulk element addition, ALTAB™ is the optimum choice.\ Jump to our main ALTAB™ product page here. ALTAB™ concentrated alloying additives are a carefully controlled mixture of alloying element (75%, 80%, 85% and in some cases up to 100%) in powder, sponge or needle form, aluminium powder and/or a sodium-free non-hygroscopic flux. Dissolution relies on the alloying element powder particles forming aluminides. Stirring the melt greatly enhances dispersion of the aluminides, resulting in improved recoveries. Some ALTAB™ grades contain flux – preferred where speed of dissolution is important or when low melt temperatures and stirring difficulty are issues. The flux aids in removal of the oxide film found on any powder, sponge or needle particle to expose the metallic element to molten aluminium. ALTAB™ Recommended Addition Practice After calculating the required addition, skim off heavy dross and add the self-sinking ALTAB™ packs, or individual tablets evenly over the melt surface. Hold the bath temperature for 5-10 minutes, then stir well to maximize recovery and homogeneity. To make our product range even more versatile, we offer a line of mini-ALTAB™ alloying tablets. These smaller tablets were developed for applications such as additions to channel induction furnaces, transfer launders, semi-automatic bulk charging systems and precise compositional adjustment for smaller foundries. Our world-wide technical services team can help you reduce alloying costs and achieve desired cast and product properties with ALTAB™ and mini-ALTAB™ alloying tablets. ALTAB™’s versatility and cost-effectiveness, combined with Metallurg Aluminium’s experience in casting processes, can enhance your production and improve your bottom line. Note: ALTAB™ and mini-ALTAB™ should both be stored in a dry area, preferably under cover. Do not add any wet product to molten metal.
