In this comprehensive guide, we’ll explore everything about NiTiCu Shape Memory Alloy Spherical Powder, from its composition and properties to its applications, specifications, and pricing. Let’s dive in to see how this material is shaping the future of engineering and manufacturing.


What is NiTiCu Shape Memory Alloy Spherical Powder?

At its core, NiTiCu Shape Memory Alloy Spherical Powder is a nickel-titanium alloy with a copper addition, designed to offer superior shape memory performance and thermal properties. The powder’s spherical geometry—achieved through advanced techniques like gas atomization—ensures excellent flowability, packing density, Và precision in manufacturing processes.

So, how does this material work? It relies on the shape memory effect (SME), where the material “remembers” its original shape and can return to it after being deformed, simply by heating it. Think of it as a spring that bounces back to its original position. Combined with superelasticity, NiTiCu alloys are highly sought after for applications requiring flexibility, reliability, Và precision.

The addition of copper in the alloy enhances its thermal stability, reduces hysteresis, and makes it more suitable for high-cycle fatigue applications. In powdered form, it becomes ideal for 3D printing complex components, repairing high-precision parts, Và thermal spraying for protective coatings.
