Neith Metals, based in Cairo, Egypt, stands out as a leading manufacturer and supplier of high-performance Nitinol Shape Memory Bars. These bars are celebrated for their remarkable shape memory and superelastic properties. The company is dedicated to delivering advanced materials that adhere to international standards, fostering innovation across a variety of industries. With cutting-edge manufacturing techniques and rigorous quality control, Neith Metals produces Nitinol Bars that embody precision, reliability, and durability. These bars are highly regarded for their outstanding functional characteristics and find extensive use in critical sectors like medical, aerospace, robotics, and engineering.
Nitinol Shape Memory Bars are made up of nearly equal parts nickel (55–56%) and titanium (44–45%), creating a unique intermetallic compound that allows for shape memory and superelastic behavior. Mechanically, they boast a tensile strength ranging from 900 to 1200 MPa, along with excellent fatigue resistance and the ability to revert to their original shape when heated. Their superelasticity enables them to recover up to 8% strain without any permanent deformation. Additionally, Nitinol offers high corrosion resistance, biocompatibility, and thermal stability, making it perfect for applications that require adaptability, precision, and long-lasting reliability.
