Nestled in the heart of Kinshasa, Sadiki Metals stands as a dedicated manufacturer and supplier, bringing world-class material innovation directly to the Congo. We are proud to produce the remarkable Nitinol Shape Memory Bar, a testament to local expertise meeting global technological standards. Our focus is on providing reliable, high-performance materials that empower industries across the region, fostering growth and enabling groundbreaking applications right from our own community.
Our Nitinol bar is a unique alloy composed of nearly equal parts nickel and titanium. Its true marvel lies in its mechanical behavior: it possesses the ability to “remember” its original shape. After being deformed, a simple application of heat will cause the bar to spring back to its pre-set form, a property known as the shape memory effect, combined with impressive superelasticity.
