Medical nitinol processing: How NiTi is turned into wire, tubes and sheets for medical devices

By

One result of medical nitinol processing is a stent; pictured are two stents made of medical-grade nitinol, one compressed and the other expanded.

Medical nitinol processing transforms raw nickel-titanium alloy into wire, coils, tubes and sheets for medical and dental device manufacturers.

We previously covered nitinol’s journey from the earth’s crust through high-temperature melting crucibles and forging operations to create nitinol ingots and then smaller, more workable shapes such as rods and plates.

But turning those into wires, coils, tubes and sheets can be challenging due to the same superelastic and shape memory properties that make nitinol so appealing for a variety of advanced medtech applications.
