Alloy choice for aluminium castings
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:
•AlSi10Mg (239 A)
•AlSi9Cu3 (226 D)
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).
Alloys with better mechanical properties produced in the Talum Group.
