Aluminium alloy rheogreen
Rheogreen
Weight reduction is key in modern designs. The alloy is developed to replace alloys as DIN226/46000/ADC12. It gives designers the ability to design very complex shapes with thin walls in combination with a low-cost alloy. The alloy is based on 100% recycled aluminium, with a max of 5.5% Silicon, to lower the carbon footprint in your product. Typical applications: pump housings, ECU covers and AC parts.
GENERAL DESCRIPTION
An alloy developed for rheocasting, having good castability properties in semi solid state. Usually it is in range of 30 40 % solid state. Reasonably good mechanical properties. Key properties are good mould filling abilities and high thermal conductivity.

SUITABLE APPLICATIONS
An alloy intended only for the rheocasting method. Excellent
for complex and thin walled castings, but also useful in applications with bigger wall thicknesses in combination with lower demands in mechanical properties.
HEAT TREATMENT
The alloy can be artificially aged or precipitation hardened,
if the porosity in the casting are kept low.
