what metals are used in shape memory alloys
Other common SMA's include copper-zinc-aluminum-nickel and copper-aluminum nickel. Shape memory alloy is commonly known as, and marketed under, the following names: SMA. smart metal. memory metal. memory alloy. muscle wire. smart alloy.
Smart alloys - higher. Smart alloys have unusual properties. Nitinol is an alloy of nickel and titanium, and is known as a shape memory alloy. If nitinol is bent out of shape, it returns to its original shape when it is either heated or an electric current is passed through it.
Memory Metal. Introduction. In 1965, the first of a series of metal alloys of nickel and titanium was produced by the Naval Ordnance Laboratory. These alloys are called Nitinol, for Nickel Titanium Naval Ordnance Laboratory. Many of the alloys have a rather remarkable property: they remember their shape.
