NiTiCu Shape Memory Alloy
Verifiedmetal· NiTiCu· Nickel-Titanium-Copper SMA
NiTiCu is a copper-modified nickel-titanium shape memory alloy that combines the reversible phase transformation behavior of NiTi with improved thermal stability from copper alloying. The addition of copper narrows the thermal hysteresis and raises transition temperatures, making this alloy useful for applications requiring precise actuation within constrained temperature windows or where repeatability across thermal cycles is critical. Unlike binary NiTi, the ternary composition offers better control over the austenite-finish and martensite-start temperatures, reducing energy losses and improving cycling durability in temperature-sensitive systems.

Safety & Biocompatibility
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
