Strengthening of selected aluminium alloys
21ScRare earth · outside the lanthanide series
Rare-earth element 21
Scandium
Small additions can help make aluminium alloys lighter, stronger and easier to weld.
Scandium · separate reporting contextWhy it is used
The properties behind scandium applications.
High-temperature ionic conductivity in specialised ceramics
Scandium is part of the 17-element rare-earth family and is treated separately in historical Minas Americas assay-table context.
Typical applications
Where scandium is commonly used.
Aluminium-scandium aerospace alloys
Solid-oxide fuel cells
Specialised lighting and materials research
Applications refer to suitable rare-earth materials, compounds or produced isotopes—not raw mineral material. Product designs and formulations vary.
Connected technologies
What the element does inside a system.
Route to use
A head assay is several steps from an industrial material.
- 01Mineral-bearing material
Geology and assays establish occurrence and distribution.
- 02Recovery and separation
Testwork must establish what can be mobilised, recovered and purified.
- 03Application-grade material
Oxides, metals, alloys or compounds must meet a controlled specification.
- 04Component or system
Manufacturers design the material into a qualified product.
Project reporting context
Treated separately in historical assay-table context.
Scandium · separate reporting context
Scandium belongs to the 17-element rare-earth family. Historical Minas Americas assay tables treated it separately from the reported TREO columns; that reporting boundary is not evidence that scandium is absent from geological material.

Applications are representative rather than exhaustive. They describe industry uses of rare-earth materials, compounds or produced isotopes; they do not describe a product currently made by Magnes or establish that an element will be commercially recovered from Minas Americas.
