Material Highlights: Nickel-Titanium at Its Best

At the heart of this wire is a carefully balanced nickel-titanium (NiTi) alloy. We fine-tune its composition for dependable shape memory effect (SME) and superelasticity (SE). The wire “remembers” its original form and recovers after deformation when heated. It also demonstrates excellent fatigue performance across repeated cycles. Because of its intrinsic biocompatibility, nitinol shape memory wire is widely used in sensitive environments such as the human body.

Engineered Oxide Layer for Real-World Durability

A naturally oxidized surface is formed under precisely controlled high-temperature conditions. The resulting titanium-rich oxide layer brings significant technical benefits:

• Corrosion Resistance – Protects the base alloy in wet, saline, or chemical environments

• Biocompatibility – Enhances safety in implantable and medical-grade applications

• Reduced Friction – Minimizes surface galling and enhances dynamic performance

• Cost-Efficiency – Often eliminates additional plating or coating steps

• Consistent Aesthetics – Dark grey, matte finish for a professional appearance
