Up to 60 % less weight

Rheocasting components bring lightness to vehicle construction

SAG is the technology leader in rheocasting – a special casting process in which aluminium is cast in a semi-solid or semi-liquid state. This so-called semi-solid process has many advantages.

Rheocasting is a special semi-solid casting process for aluminium. Up to 60 % weight reduction compared with steel parts and other significant advantages were honored by VOLVO with an innovation award.

Innovative technologies for processing light metal alloys have undergone enormous development in recent years. These include rheocasting – a special casting process in which aluminium in a semi-solid state is processed into lightweight components with special material properties.

Advantages of Rheocasting
at one glance

Up to 60 % less weight

compared to steel parts of the same size. Areas of application: Vehicle components, chassis parts, crash-relevant parts.

Optimum mechanical strength and elongation

Higher fatigue strength than steel. Areas of application: Vehicle components, chassis parts, crash-relevant parts.

Best weldability and pressure density (helium density)

Areas of application: Vehicle components, chassis parts, pressure vessels, radiators, pumps.

Best thermal and electrical conductivity

20 % higher thermal conductivity, improved EMC properties, best for applications in telecommunications and battery technology/power electronics

Cost-effective because of near net-shape

No milling, deburring, grinding necessary. Areas of application: Visible components, interior parts, brakes.

Allows wall thickness transitions and freedom of design

Any design possible, even for components with different wall thicknesses, e.g. in the field of bionics. Best functional integration, weight optimization at equal installation space.
