General description of properties:
Universal alloy with very good castability, particularly suitable for pressure die casting. Little tendency towards forming surface
defects and internal cavities by shrinkage on solidification. Very good machinability

Suitable applications:
For wide range of applications. Also for complicated and thin-wall castings. Especially suitable for highly stressed pressure die castings.

Heat treatment:

Not usually age hardened
Others each max 0,05%
and total max 0,15%
