Scandium also interrupts melted aluminum crystalizing at a molecular level when the metal cools. This means that the properties of the alloy are less likely to be affected by heat-treatment and welding, so a scandium-infused aluminum alloy is less likely to crack while cooling. This is especially valuable in high-strength aluminum, like …
