Memory Alloy
Shape memory alloys (SMAs) are a unique class of smart alloys that have the ability to ‘remember’ their original shapes. SMAs can be deformed when cold (Martensite) and return to their memorized shapes when heated (Austenite) even after strong deformation, this is the so-called Shape Memory Effect (SME). The other main property of SMAs is the super-elastic effect; superelasticity allows the materials to be recovered from large mechanical stresses without plastic deformation. Beside these two major properties, compared to the conventional alloys, SMAs also show excellent traits such as high strength, light weight, biocompatibility, fatigue resistance and wear resistance.


Shape Memory Alloy Field
The most commonly used shape memory metal is Nitinol (NiTi), which comprises a roughly equal parts of Nickel and Titanium, in addition to excellent shape memory effect and superelasticity, it also has excellent corrosion resistance, high damping performance and biocompatibility. They are broadly used in the fields of medical, military, aerospace, industrial, consumer electronics, home appliances, et cetera.


Shape Memory Alloy Application
TRIAD pioneered and matured the R&D and applications of SMAs in China. With more than 20 years of experience in producing and applying NiTi shape memory alloys, we have accumulated mature production technologies and have achieved long-term product applications in eyeglass frames, underwear accessories, medical implants, temperature control sanitary wares and many other fields.
Shape Memory Alloy Products
As the pioneer of research and development of shape memory alloys in China, TRIAD explored the application of SMAs in daily life, such as the market for eyeglasses and clothing.
Nickel Titanium Shape Memory Alloy is mainly used in the middle beam and temple parts of eyeglasses, with the advantages of light weight, biocompatibility, wear resistance, and compression resistance. The super elasticity ensures the frames to be very durable and strong that they can even be bent back and forth. After more than 20 years of unremitting efforts, SMA has become the preferred material for high-end eyeglasses.
The application of SMAs to the underwire is also a significant global market for SMA; women’s brassieres have both aesthetic as well as structural requirements; NiTi underwires offer improved comfort due to the much lower elastic modulus than the conventional steel wires, and the material offers greater resistance to permanent deformation due to the frequent washing and drying.
