Frequently Asked Questions

What is Nitinol Grade 1 Wire?

Nitinol Grade 1 Wire is a nickel-titanium (NiTi) shape-memory alloy wire known for its high flexibility, shape recovery, and corrosion resistance.

What is Nitinol Grade 1 Wire made of?

It is made primarily of nickel and titanium, with the exact composition controlled to achieve the required shape-memory and mechanical properties.

Is Nitinol Grade 1 a standard ASTM grade?

Nitinol Grade 1 is commonly specified under ASTM F2063, which covers wrought nickel-titanium shape-memory alloys for medical devices.

What is the difference between Nitinol Grade 1 and Grade 2 Wire?

The main difference is their alloy composition and resulting mechanical and transformation properties. Grade 2 is formulated for higher loading and unloading plateau stresses than Grade

Is Nitinol Grade 1 Wire a shape-memory alloy?

Yes. Nitinol Grade 1 Wire is a shape-memory alloy that can return toward its programmed shape when heated above its transformation temperature.

Does Nitinol Grade 1 Wire have superelastic properties?

Yes, it can exhibit superelastic behavior when its transformation temperatures are properly controlled for the intended operating conditions.

Is Nitinol Grade 1 Wire corrosion resistant?

Yes. Its titanium-rich surface forms a stable passive oxide layer, giving Nitinol Grade 1 Wire good corrosion resistance.
