Overview of NiTi50 (Nitinol) Powder

Nitinol, a nickel-titanium alloy, derives its name from its components and discovery—Nickel (Ni), Titanium (Ti), and Naval Ordnance Laboratory (NOL). What makes Nitinol extraordinary is its shape memory effect, meaning it can return to a pre-defined shape when heated, and its superelasticity, allowing it to endure extensive strain without permanent deformation.

Why is NiTi50 powder special?
NiTi50 powder is a specific formulation of Nitinol containing roughly 50% nickel and 50% titanium. It exhibits both the shape memory effect and superelasticity, making it invaluable in applications where precise control over material behavior is needed.

Key Features of NiTi50 (Nitinol) Powder:

  • Shape Memory: Returns to its original shape after deformation when heated.
  • Superelasticity: Can undergo large amounts of strain and recover without permanent damage.
  • 生体適合性: Ideal for medical implants and devices.
  • 耐食性: Performs well in harsh environments, including inside the human body.
  • 高い疲労強度: Excellent durability over multiple stress cycles.

Now that we’ve scratched the surface, let’s take a deeper dive into its technical composition and properties.

Composition of NiTi50 (Nitinol) Powder

The unique characteristics of NiTi50 are a direct result of its composition, which is meticulously balanced to offer the best performance across a range of applications.

エレメント構成比
ニッケル(Ni)49.5% – 51%
チタン(Ti)48.5% – 50%
Impurities< 0.5% (e.g., Fe, C, O)

Why this composition matters:
A slight shift in the balance between nickel and titanium can greatly affect the alloy’s behavior. For instance, a higher nickel content tends to lower the transformation temperature (the temperature at which the shape memory effect occurs), while more titanium raises this threshold. Impurities are kept to a minimum to ensure that the material retains its unique properties.
