Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the titanium screw, leading to thread stripping or material fatigue.Always adhere to the recommended torque specifications for Grade 5 Titanium, using a calibrated torque wrench.
Using incompatible lubricants or anti-seize compounds that can react with titanium.Consult material compatibility charts and use only titanium-specific or recommended anti-seize compounds.

Common Applications

  • Aerospace and Aviation components
  • Marine and Offshore equipment
  • Medical implants and surgical instruments
