Alluminio AlSi7Mg0.6 (A357) AlSi10Mg



Alluminio (AlSi10Mg)

L'alluminio è una lega con buone caratteristiche di fusione e viene in genere utilizzata per produrre parti molto sottili e dalle geometrie complesse. Offre buona resistenza e durezza ed è quindi largamente utilizzata per modelli che devono sopportare carichi elevati.
Le produzioni in alluminio sono ideali per le applicazioni che richiedono buone proprietà termiche e peso ridotto.
Il pezzo in alluminio può essere lavorato tramite saldatura, sottoposto a processo di elettroerosione a filo, micropallinatura ed essere lucidato o rivestito se necessario.
Convenzionalmente le realizzazioni in questa lega di alluminio vendono sottoposte a trattamenti termici come la tempra per migliorare le proprietà meccaniche.
