Medical Nitinol Core Wire – Straight Configuration for Precision Devices

Medical Nitinol Core Wire in straight form delivers stable, predictable performance for advanced medical tools. Manufactured from a high-purity nickel–titanium alloy, this precision wire supports applications such as guidewires, catheters, surgical instruments, and orthodontic systems.

Because the wire is supplied in a straight configuration, it ensures easier handling, improved alignment, and tighter dimensional control during device assembly. CWT produces medical Nitinol core wire with exact tolerances and exceptionally clean surfaces to meet critical medical standards.

MRI Compatibility of Medical Nitinol

MRI systems generate strong magnetic fields. Ferromagnetic metals—such as certain carbon steels and stainless steels—can respond aggressively inside these fields, potentially causing movement or heating.

However, medical Nitinol is not ferromagnetic. Although it contains nickel, the alloy’s crystal structure prevents magnetic interaction. Titanium is naturally non-magnetic, and the bonded alloy exhibits minimal magnetic response.

As a result, many implantable devices made from  Niti are considered MRI compatible under standard medical guidelines, making it a preferred material for cardiovascular and minimally invasive technologies.
