Product Description

Nitinol Wire Description:
Nitinol round wire (NiTi wire) is a nickel-titanium alloy renowned for its shape memory effect, superelasticity, and excellent fatigue and corrosion resistance. When deformed, it can return to its original shape upon exposure to a specific transformation temperature. These unique characteristics make Nitinol the preferred material for minimally invasive medical devices, including braided products, orthodontic wires, guidewires, and various implantable surgical tools.

Key Features:

Fully independent processing and precision control
Customizable phase transition temperature range
Stable shape memory and superelasticity
Excellent straightness and resistance to bending
1:1 torque transmission for precise guidance
