An Overview Of Aluminium-Scandium (AlSc) – An Interview With KBM Affilips

What is the chemical composition of your aluminium-scandium (AlSc) and what chemical properties does this provide the alloy with?

The chemical composition of the aluminium-scandium master-alloy is 2% scandium and the balance is 99.7% aluminium. The master alloy is used to add scandium to Al-Mg-Zr containing alloys, which are used in the form of sheet and plate. These sheets and plates are mainly used by aircraft manufactures.

The scandium content in the aluminium sheet and plate varies from 0.2 – 0.4% scandium.

What are the important physical properties of aluminium-scandium?

Aluminium 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 aluminium-scandium containing alloys extremely suitable for aerospace industry.

When were the beneficial properties of aluminium-scandium first realised? How were these developed?

The beneficial properties of scandium in aluminium alloys were first utilized in Russia during the cold war period. Alloys containing scandium were used for missiles and MIG fighter jets.

What are the main application areas that aluminium-scandium can be used in?

As mentioned earlier, aluminium scandium alloys can be used in the form of sheet and plate for aerospace applications.

Other applications for aluminium scandium alloys include blades for wind-mills and sporting goods like bicycle frames, baseball bats and golfclubs.

What form does KBM Affilips provide aluminium-scandium in?

KBM Affilips provides the aluminium scandium alloy in the form of a 6kg waffle ingot.

How do you see aluminium-scandium being utilised in the future? Do you think there will be any significant changes?

The current price of scandium prevents a wider application in the aluminium industry, therefore scandium will just be used for the time being in high-end markets like aerospace and sporting goods.
