Aluminium Industry

Graphite is used throughout the complex processes in the creation and purification of Aluminium, Graphite's heat and chemical resistant properties make it an ideal material for this application. Graphite moulds and casting rings are also used throughout the aluminium industry to fabricate complex aluminium products.

Graphite fluxing tubes are used as part of aluminium process.
Graphite plates and rolls for aluminium extrusion process. Extruded aluminium is used for manufacturing aluminium window frames and doors.
Graphite shafts and graphite impellers are used in rotary purification systems for aluminium degassing, Graphite is used due to its heat and chemical resistant properties.
