Abstract
Provided is a super elastic alloy for biological use having a high biocompatibility, good processability and super elasticity, said super elastic alloy being a super elastic zirconium alloy for biological use comprising 27-54 mol % inclusive of titanium, 5-9 mol % inclusive of niobium which is a β phase-stabilizing element capable of stabilizing the β phase of zirconium, and 1-4 mol % inclusive in total of tin and/or aluminum which are ω phase-suppressing elements capable of suppressing the ω phase of zirconium, with the balance consisting of zirconium and inevitable impurities.
