Flat Wire – Superelastic Nitinol with Black Oxide Finish 0.4*0.8mm

Description

Black Oxidized Superelastic Nitinol Flat Wire (0.4mm x 0.8mm)

Introducing our premium Black Oxidized Superelastic Nitinol Flat Wire, precision‑crafted at 0.4mm thick by 0.8mm wide. This unique flat profile delivers benefits that round wire simply can’t match, including enhanced surface contact, precise torque control, and seamless fitting in slim, space‑constrained designs.

Medical‑Grade Nitinol Material

Our flat wire is made from medical‑grade Nitinol, an advanced nickel‑titanium alloy celebrated for its superelasticity, shape memory, and biocompatibility. Superelasticity allows the wire to tolerate significant deformation and spring back to its original shape, making it ideal for complex medical devices. Its shape memory effect activates upon heating, returning the material to a pre‑set configuration. Nitinol’s corrosion resistance, comparable to surgical stainless steel, ensures durability in long‑term applications.

Superelastic Nitinol Flat Wire Specifications

Although this specific product is 0.4mm x 0.8mm, we can manufacture flat Nitinol profiles ranging from 0.05mm to 3.0mm in thickness and 0.1mm to 10.0mm in width. This allows design teams to select the ideal dimensions for medical, aerospace, or consumer applications. We also custom‑cut lengths for precision assembly.

The Black Oxide Advantage

The black oxide surface provides significant benefits. It improves corrosion resistance, reduces surface friction, and increases fatigue life. This coating creates a durable, attractive, low‑reflectivity finish that won’t peel or flake, making it ideal for medical implants and precision devices.

Applications of Superelastic Nitinol Flat Wire

This flat wire excels in highly demanding environments:

• Medical Devices: Guidewires, catheter reinforcements, endoscopic tools, orthodontic archwires, and orthopedic fixation.

• Industrial Actuators: Smart release mechanisms and aerospace controls.

• Fluid Systems: Seals and valves for critical flow applications.

• Electronics & Consumer Products: Connectors, probes, springs, and precision wearables.

Understanding Nitinol Heat Treatment

Nitinol does not “harden” when heated like steel. Instead, heating defines its shape memory properties after cold working. Careful thermal treatments enable precise activation temperatures (Af) and long‑term performance, making it ideal for superelastic and shape‑memory applications.
