| Biocompatibility, mechanical properties, radiopacity, and
overall performance of medical devices (stents, implants and
tools) greatly depend on their raw material.
STI practices extreme selectivity in the raw materials applied
for its medical devices and medical implants. Our suppliers
are all experts, who are committed to the highest quality
standards needed for meeting the specific implants requirements.
All shipments of raw materials are accompanied by detailed
documentation and quality certificates.
STI’s stents are manufactured from seamless metal tubing
with tight tolerances in dimensional accuracy, concentricity
and a smooth and defect-free surface, to optimize laser cutting
and polishing operations.
Based on our experience, we can help you select the best material
for your specific application.

|
| Stainless Steels (most common
316LVM) |
| • |
Very successful for stent applications,
despite a weak radiopacy |
| |
|
| Nickel Titanium (NiTinol) |
| • |
Selected for exceptional flexibility and shape
memory effect upon heating |
| |
|
| Cobalt-based alloys (Cobalt
Chromium, L605) |
| • |
Selected for improved density, elasticity and
strength |
| |
|
| Refractory metals (Tantalum,
Niobium, Tungsten) |
| • |
Normally used as alloying elements to improve
radiopacity and MRI visibility |
| |
|
| Precious metals (Platinum,
Iridium, Gold) |
| • |
Materials of choice for improving radiopacity
of other alloys. |
|
 |
|
|
| |
|
| STI uses different materials, tubes and flat
parts, for applications other than stents, such as Titanium
for orthopedic implants, Aluminum sheets and foils for aviation
industry applications, Copper sheets for infrared sights, Ceramics
for heat insulators in mini rotor applications, Gold sheets
for the semiconductor industry, precious and semi-precious metals
for jewelry, and many more. |
