NiTi Tubes (Ni-Ti, Nitinol, Nickel Titanium)

Characteristics of NiTi Tubes

It unites the characteristics of super-elastic alloy with that of shape memory alloy. Especially, it is superior in restoring force, which is essential to medical instruments, stands out so that there is high demand for Niti tubes in medical field. However, it is not suitable for welding processing. We produce βtitanium tubes as elastic alloy which is suitable for welding, and line up them to compensate demerits of NiTi tubes .

Our super-elastic Niti tubes have excellent flexibility, kink prevention, and shape memory, and they have been used for a variety of purposes such as cardiovascular translational operation and a cartheter.
It takes approximately 40days from an order date to deliver Niti tubes of original specifications.

Outer diameter polishing of tubes(Oxide film removal)

Outer diameter polishing of tubesBy centerless polishing and pickling, an oxide film can be removed. The beautiful surface of outer diameter can be seen even on camera monitor at operation.

Laser processing

In general, dross (burred dregs of melted metals) emerges inside cutting surface after laser cutting. However, our own dross removing technique can offer clean, smooth cutting surfaces.

[spiral milling]

spiral milling. FUTA-QIn addition to super elasticity Ni-Ti has, spiral sulcus made by laser fine processing, which is also used for stent processing, enables to move tubes flexibly.
By adjusting slit width and pitch, flexibility and springness can be well-controlled in every portion.

[slit processing (flexible tubes)]

slit processing (flexible tubes). FUTA-QOur own design of slit processing made evenφ6 tubes (ID) enable to move freely. In addition, this epoch product combines operability of bending ductily, freely, and flexibly with strength which Niti has.

bore polishing

We can polish the inside of tubes with φ0.3mm I.D. at minimum, and surface roughness Ra0.1 at minimum. The length can be up to 700mm at maximum. (If you choose I.D.φ0.3mm and Ra0.05, the maximum length is 300mm)
