What is aluminum-scandium master alloy? - hmwadeseo - 02-15-2023
The chemical composition of the aluminum-scandium master alloy is 2% scandium and the balance is aluminum. The master alloy is used to add scandium to Al-Mg, Al-Mg-Zr, and Al-Zn-Mg containing alloys, which are used in the form of sheets, plates, and profiles. These materials are mainly used in aircraft, military, and other demanding applications.
Important physical properties of Al-Sc alloys:
Aluminum scandium-containing alloys combine high strength, ductility, weld-ability, improved corrosion resistance, and a lower density (as a result of the magnesium in the alloy). The combination of all these properties makes aluminum scandium-containing alloys extremely suitable for the aerospace industry.
