EinLanzium

Basic knowledge
EinLanzium is a bright purple and very dense metal related to gold. Much like how Deutirium is a variant of Hydrogen, so is EinLanzium to Gold. Most commonly found naturally on KaTet, artificial versions have been made in small quantities on Earth.

Special Properties
EinLanzium, being a dense metal, is often used for armor on tanks and spaceships, though the taoKa have used it for the creation of their body armor and weaponry. When electrified, two unusual things happen. EinLanzium begins to act like a muscle in reaction to the 'thoughts' of any living creature touching it. AND its mass reverses. It still remains dense, but the apparent weight takes a shift from positive[more weight] to negative[less weight]. This makes it prized on heavy worlds like Katet, where the gravity is too high for nromal metal or ceramic armors to be effective or safe. It's also used on hover vehicles for structural integrity and in certain types of armors, such as the Royal dress worn by Krameil, the basic body armor of the taoKa, and the 'Titaness' powered armor used byy the Zen-La and some humans.

these two facts may be the only 'unique' properties of EinLanzium, but those two simple facts have changed technology as we know it in a BIG Way!
