Shape Memory Alloys

Nickel Titanium Naval Ordinance Laboratory was discovered in 1958 and since then has becoming increasingly popular as material for a wide range of applications: from critical bio-medical stents and orthopedic implants to leisure sports items. The production of Nitinol has always represented a challenge caused by the segregation of phases and the need to accurately control the processing atmosphere to avoid titanium depletion.

With EPoS’ technology Nitinol can be easily processed to theoretical density in air without oxidation thereby allowing lean production of small simple components with reduced or no machining. Both super-elastic and shape memory grades can be produced either with or without a heat treatment after sintering.
