Thin-wall nitinol tubing properties

Material challenges

Thin-wall nitinol tubing is hard to work with. Nitinol is special because it bends and goes back to its shape. These features make nitinol tubing good for medical and advanced uses. But they also make it tricky to process. You have to watch the temperature very closely. Small heat changes can mess up nitinol’s shape memory and bending.

The wall thickness of nitinol tubing must be exact, within ±0.01 mm.
Careful gun drilling makes the tubing strong and safe for doctors.
Laser micrometers and ultrasonic gauges check every tube to meet rules.
Nitinol’s bending makes the tubing spring back after cutting, so it is hard to keep the right size.
The tubing gets harder fast as you work on it, which wears out tools.
Nitinol does not move heat well, so heat builds up quickly and needs good cooling.
It is tough to keep the same material features all along the tubing because small changes can happen.

Here is a quick look at how nitinol’s features change cutting:

Property	How It Changes Cutting Methods
Superelasticity	Tubing springs back, so it is hard to keep the right size.
Work Hardening	Tubing gets harder when you cut it, which wears out tools.
Low Thermal Conductivity	Heat builds up at the cut, so you need special cooling to protect the tubing.

Application demands

Thin-wall nitinol tubing is used in many medical and advanced jobs. Medical tools need tubing that bends but does not kink and goes back to its shape. Nitinol tubing helps stents, catheters, and guidewires work better in heart procedures. Its bending and shape memory help devices fit inside the body, which makes them work well.

Doctors use nitinol tubing for small surgeries because it does not kink and moves easily in tight spaces. You also see thin-wall nitinol tubing in advanced jobs where being exact and reliable is important.

Micro-laser cutting helps by making tiny details for stents, guidewires, and closure devices. You get tubing that meets strict medical rules and helps keep treatments safe and effective.

Micro-laser cutting process

Precision and control

Micro-laser cutting gives you very exact cuts. A focused laser melts or removes material from thin-wall nitinol tubing. The cuts can be smaller than a strand of hair. You can use tubing as thin as 0.0011 inches or as thick as 0.016 inches. Special lasers, like femtosecond and picosecond lasers, help keep the tubing’s shape. These lasers use very short bursts, so there is less heat and the edges stay smooth.

You can change the laser’s power, speed, and how many times it goes over an area. This helps you protect nitinol’s superelastic and shape memory features. CNC control and special lenses guide the laser along tricky paths. You can make tiny, detailed parts for medical devices like stents and guidewires. Micro-laser cutting gives you high accuracy and does the same thing every time, which is important for medical and advanced jobs.

Here is what micro-laser cutting can do:

Cutting width: 15~30 µm
Precision tolerance: ≤±10 µm
No burrs and smooth incision
X-axis accuracy: ±7 microns
Rotary axis accuracy: ±50 arc-seconds

Micro-laser cutting uses advanced lasers to give fast, repeatable, and clean cuts. You get the right size you need for thin-wall nitinol tubing.

Minimal thermal impact

Micro-laser cutting is special because it keeps heat low. Lasers with longer pulses can make a bigger hot area, which can hurt nitinol’s special features. Femtosecond lasers use very short bursts, so the hot area stays small. This means you get cleaner cuts and keep the tubing’s superelasticity and shape memory.

Modern micro-laser cutting systems let you cut nitinol tubing with almost no heat going to the rest of the tube. You avoid changes in the tubing’s important temperatures, so it works the same way every time. Studies show the right laser can keep temperature changes very small. This matters for medical devices, where even small changes can affect safety and how things work.

Micro-laser cutting keeps nitinol’s special features safe.
You avoid bending and keep the tubing’s shape.
The process gives you smooth, burr-free edges every time.

Micro-laser cutting gives you the control and accuracy you need, while keeping the tubing safe from heat. You can trust this process for tough medical and advanced jobs.

Thin-wall nitinol tubing micro-laser cutting advantages

Burr-free cuts

Micro-laser cutting gives thin-wall nitinol tubing smooth edges. Lasers focus energy tightly, so you do not get rough spots. Burrs can cause problems in medical devices. Micro-laser cutting uses sublimation, turning nitinol from solid to gas. This stops solid impurities and dross from sticking. You control the heat well, so the tubing stays safe and smooth.

Laser cutting works great for thin-wall nitinol tubing and gives burr-free cuts.
Sublimation keeps solid impurities from sticking to the tubing.
You can change laser settings to keep the heat-affected zone small, which helps you get clean edges.

Medical devices need burr-free cuts. Smooth edges mean less risk for patients. You do not need extra time to remove burrs or fix tubing. This makes your process faster and safer.

Here is how burr-free cuts help medical devices:

Benefit	Description

Complex shapes

Micro-laser cutting lets you make complex shapes in nitinol tubing. You can cut with high accuracy, even for tiny parts. Lasers help you make shapes that other tools cannot. You can design tubing with spiral cuts, dogbone cuts, or interrupted spirals. These shapes help devices bend, flex, or stay strong where needed.

Shape Type	Description
Interrupted Spiral Cut	Switches between flexible and solid zones, perfect for catheter shafts that need both strength and flexibility.
Spiral Cut	Gives continuous flexibility, which helps devices move through tight spaces in the body.
Dogbone Cut	Limits bending to certain directions, giving you strong control over how the tubing moves.
