Alloys for aluminium castings are chosen according to two criteria:
- purpose, use and demanded product properties,
- alloys which have been applied in the production, as this results in lower production costs.
The most frequently used alloys are:
•AlSi7Mg0,3
•AlSi7Mg0,7
•AlSi8Cu3 (226A)
•AlSi10Mg (239 A)
•AlSi9Cu3 (226 D)
•AlSi10MnMg
•AlSi12Cu1 (231)
We developed a technology of casting and alloys, which on average have up to 30% better mechanical properties (hardness, ultimate strength, permanent dynamic strength etc.) than those minimally required by the standard EN 1706 (table below).
