An aluminium, the piston from an aluminium cast alloy and method for the production of an aluminium

摘要

The invention relates to a an aluminium, wherein the alloy is a hyper-eutectic aluminum-silicon-based alloy, the more than 30 ppm to 150 ppm of phosphorus (p) and at least 10 ppm to not more than 200 ppm of ytterbium (yb) and further fine crystalline primary silicon. Furthermore, a piston from this an aluminium and a process for preparing these discloses aluminium.
