The thing with the memory: shape memory alloy

Shape memory alloy – the name says it all: It does not matter how much they are bent and deformed, they can always "remember" their original form when temperature is increased. This characteristic brings other benefits with it, like for example elasticity and resilience. Whether for stents, surgical devices or micro valves, medical technology has also recognized the advantages of nickel-titanium, nickel-titanium-copper and other shape memory alloys. Read more about their characteristics and uses and how much potential these materials still offer in our Special May.
