Aluminium Scandium Zirconium Alloy

Name: Aluminum-Scandium-Zirconium Master Alloy

Formula: AlSc2%Zr1%

Packing: In wooden carton or pallet

Appearance: Silvery lump ingot/waffle ingot

In order to produce high quality cast and wrought strong and light weight alloys, it is necessary to improve their microstructure during both solidification and subsequent thermomechanical treatment. The structure of dispersion-strengthened aluminium alloys is controlled by an addition of modifying aluminium based master alloys with transient element, which form thermally stable disperse phases with aluminium inhibiting graub growth. The Al-Sc-Zr master alloys demonstrate that the modification with this master alloy make it possible to obtain a fine grain structure, to increase the recrystallization temperatue, to decrease the sensitivity to corrosion cracking, to influence aging process, and to improve the mechanical properties and weldability of aluminium alloys. A joint of addition of Sc and Zr plays a significant role in Al-Zn-Mg-Cu based alloys, providing the precipitation of a phase that prevents grain growth, which if of great importance for subsequent thermal treatment of precipitation-hardening aluminium alloys.

Processing Method:

Doping high purity scandium and zirconium to high purity aluminium, melting and mixing in intermediate frequency furnace, deslagging.

FAQs:

Why is scandium added to aluminum?

Image result for scandium alloy

Scandium strengthens aluminium in three different ways: grain refining, precipitation hardening, and inhibiting recrystallization, or grain growth. Due to its fine grain refinement, scandium alloys reduce hot cracking in welds, increase strength in the welds and deliver better fatigue behavior.

What scandium master alloys you make?

HAMM can make almost all kind’s of scandium contained mamster alloy according to customer’s demands.

How is scandium used in aerospace?

Scandium is used in alloys to increase strength, lighten weight, and help resist corrosion. By adding a small percentage of scandium it allows aluminum sheets to be welded to each other, which is then used in the aerospace and automobile industries.

Is scandium stronger than titanium?

Scandium can be stiffer and lighter than titanium, but not as strong or durable.
