Scandium Powder

Scandium Powder is an ultrafine metallic powder that we produce to the highest quality with a purity of 99.9%. Its unique properties include low density, high strength-to-weight ratio and excellent electrical conductivity. Available in 3 sizes, it can be used to enhance mechanical characteristics in electronics, aerospace components and aluminum alloys. Scandium powder can also be added to aluminum alloys for the creation of heat-treatable welded structures. Scandium Powder’s combination of light weight and strength make it well suited for aerospace and automotive applications where reducing weight is critical.
