Home > Nitinol Superelastic Tube
Okoye Nickel Alloys, a leading manufacturer and supplier based in Kinshasa, Congo, focuses on crafting high-quality Nitinol Superelastic Tubes that are engineered for precision and performance in challenging applications. These tubes, made from a Nickel-Titanium (NiTi) alloy, boast remarkable superelastic and shape memory characteristics, enabling them to return to their original shape after being deformed. Known for their outstanding flexibility, corrosion resistance, and biocompatibility, Nitinol Superelastic Tubes are perfect for use in medical devices, aerospace systems, and industrial automation. Okoye Nickel Alloys is committed to delivering consistent quality, precise dimensions, and strict compliance with international standards to ensure reliability and durability.
Nitinol Superelastic Tubes consist of about 55% nickel and 45% titanium, creating a nearly equiatomic alloy that gives rise to its superelastic properties. This unique composition allows for strain recovery of up to 8% without any permanent deformation. The tubes exhibit a tensile strength of approximately 895 MPa and a yield strength of 560 MPa, while also maintaining impressive flexibility and fatigue resistance. Nitinol is known for its excellent corrosion resistance, biocompatibility, and thermal stability, making it suitable for dynamic environments. Its ability to undergo austenite-martensite phase transformation provides the essential shape memory and elasticity needed for precise mechanical and biomedical applications.
