Sonstige Eigenschaften
AlZbn10Si8Mg is a self-hardening virgin alloy that is particularly used when good strength values are required without the need for heat treatment. Particular attention should be paid to the high 0.2% yield strength. The low iron content has a particularly beneficial effect on the mechanical properties, which can also be traced to good fatigue strength.
The alloy is noted for its very good casting properties. It can be processed in sand casting as well as in mould casting and low-pressure mould casting.
It can be processed excellently in a way that removes chips, and can also be mechanically polished to a high level. A certain tendency towards tension crack corrosion must be considered on a case by case basis.
