Introduction
Aluminium / aluminum and its alloys are used in an ever-increasing number of applications.
Aluminium / aluminum 7000 series have excellent fatigue properties, except in the T6 temper. These alloys can be spot welded but not fusion welded.
Aluminium / aluminum 7017 alloy is a heat treatable wrought alloy. It age hardens naturally.
The following datasheet will provide more details about aluminium / aluminum 7017 alloy.
