Strange Metal is a theoretical compound that Tracy Brand believes composes Savitar's Armour. The compound is designed to disperse high amounts of heat at high temperatures. Savitar uses this metal in his armor to avoid building up too much friction essentially stopping him in his tracks. Tracy believes that if Team Flash can develop a device to neutralize the Strange Metal's properties, Savitar's own speed would cause an energy backlash that would seal him in the Speed Force.
