EN AC-AlSi12Cu1(Fe)
EN AC-47100Eutectic aluminum die casting alloy with copper addition for improved hot-tear resistance compared to EN AC-46000. Si ~12% provides excellent castability. Cu ~1% improves strength and machinability. Higher Fe tolerance for HPDC anti-soldering. Used for complex thin-walled die castings, automotive transmission and structural components requiring good hot-tear resistance, electronics housings, and industrial die cast parts. Equivalent to ASTM A383.0.
