super elastic iron alloy maintains its original shape even after serious stretching,The iron alloy's stress level is about twice that of nickel titanium ,metal's super-elasticity allows it to return to its original form and gives it additional properties, such as ductility and a change in magnetization and it can be made into a very thin wire that can reach the inner part of the body like the brain to deliver stents , which are tubes placed in blood vessels to stop them from collapsing. Currently, heart stents are delivered into the body using nickel titanium but the diameter of the wire is too thick to go into the brain , The super-elastic iron alloy also be used for buildings in earthquake prone areas the buildings will deformed by earthquake, but super elastic alloy can return the building to its original structure
