Undiscovered Scandium Market Set to Boom

    Nice article in gist, however, slight correction is required, regarding:

    “Just using the alloy in the rivets for a plane would cut the craft’s overall weight by 10% to 15%.”

    should be corrected to:

    “By using Scandium-Aluminium alloys (+/- other elements, e.g. Mg), the component fuselage, wing and tail plates on a plane can be welded together instead of riveted, saving up to 10-15% of the total plane weight by eliminating the need for rivets.”

    (This is due, in part to Sc-Al alloys increased creep resistance, compared to existing Al-alloys used on planes: which can’t be welded safely, hence the need for rivets; adding ~10-15% extra weight to the plane, apparently).
