Advantages of the Titanium Hex Bolt DIN933
High Specific Strength:
With a density of only 4.51 g/cm³, titanium is lighter than steel
yet offers superior strength, resulting in lightweight but highly
durable fasteners.
Excellent Corrosion Resistance:
Titanium forms a stable oxide layer, making it suitable for harsh
chemical, marine, and industrial environments.
Wide Temperature Range:
DIN933 titanium screws can operate effectively from –250°C to 600°C, maintaining mechanical stability without deformation.
Non-Magnetic and Biocompatible:
Titanium is a non-magnetic and non-toxic metal, ideal for use in medical implants, electronics, and precision instruments.
Superior Damping Capability:
Titanium’s long vibration attenuation time makes it ideal for ultrasonic medical devices, high-end audio equipment, and precision instruments.
