Recommended Materials for Medical Device Parts

Comparison of material properties and suitable applications for medical device parts.

Material Properties Suitable Parts Notes
SUS316L Biocompatible, good corrosion resistance Endoscope parts, implant auxiliary components Common first choice in medical devices
Titanium Ti-6Al-4V Lightweight, biocompatible, high strength Implants, surgical instruments Low thermal conductivity — requires controlled machining parameters
17-4PH (SUS630) High strength, heat-treatable Surgical instrument structural parts Combines strength and corrosion resistance
A286 High-temp oxidation resistant Special-function parts Evaluated per application
SUS304 Corrosion resistant, reasonably priced Non-implant peripheral parts Lower cost than 316L
