Titanium Parts FAQ

Gr5 or Gr23 for a medical adjacent part?

Gr5 (TC4) for structural parts; Gr23 ELI when fracture toughness matters in fatigue loaded or medical adjacent applications. Both are stocked with certificates.

Why is titanium machining quoted differently?

Low cutting speed, rigid setups and tool life planning: titanium punishes assumptions. Our quotes state the route so the price reflects real process, not guesswork.
