Aluminium Alloys – Briquetted Alloying Additives for Aluminium Alloys from Metallurg Aluminium

March 21, 2007 – 7:32 am

Metallurg Aluminium’s briquette-form alloying products are used in casthouses and foundries for accurate compositional adjustments of alloy melts or for bulk element addition. The distinctive shape of these products is created as the product’s components are compressed between pillow-shaped indentations on two opposing rollers. This shape promotes ease of transport, storage and handling – both in large-scale casthouse furnace additions and in smaller-scale foundry additions.

Our briquetted alloying products contain a carefully controlled mixture of alloying element (75%, 80% or 85%) in powder form, aluminium powder and optional sodium-free non-hygroscopic flux (in our Quick-Sol™ alloying briquettes only). The briquettes are produced using a patented process that assures a high degree of element purity, product consistency and process control. Dissolution relies on the alloying element powder particles forming aluminides. It is recommended that the briquettes be charged after melting is completed and the bath has been skimmed; recommended minimum temperature of 720°C (1,328°F). Normal furnace stirring to ensure a uniform mixture is sufficient to assure complete dissolution of the briquettes.
