Considered a critical mineral by countries including the United States, Canada and Australia, scandium is a rare, versatile and useful metal.
Scandium is the most effective known microalloying element that can strengthen aluminium, while also offering improved flexibility, resistance to heat and corrosion, and lighter weight.
For this reason, military and civilian aircraft have used aluminium-scandium alloys for decades to improve fuel economy, manoeuvrability and range. These alloys are used in the aerospace, energy (for solid oxide fuel cells), automotive, and 3D printing industries.
They’re also used in sporting equipment, such as baseball bats, lacrosse sticks and bicycle frames, because of their lightweight properties – bicycle manufacturers estimate that scandium reduces the weight of their aluminium frames by up to 15%.
Scandium is also used in electronic ceramics, lasers, LED lighting, glass and many more applications where its unique properties make it a valuable addition.
