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.
Up to 60 % less weight
Rheocasting components bring lightness to vehicle construction
Rheocasting is a special casting process in which aluminium is casted in a semi-solid or semi-liquid state.
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 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.
High voltage electronic housing
Special vehicle part
Air spring top mount
