Machining Grade 23 (Ti-6Al-4V ELI)

Machinability is rated difficult — a genuinely demanding material — rigid setups, premium tooling and conservative parameters, with cycle time and tool wear to match. Titanium’s low thermal conductivity concentrates heat at the cutting edge. Correct coolant application, sharp carbide tooling and conservative cutting parameters are essential — Grade 5 and Grade 23 in particular demand rigorous tool change intervals to maintain dimensional consistency.

Our standard achievable tolerance on Grade 23 (Ti-6Al-4V ELI) is ±0.010mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: Electropolish, Ra ≤0.4µm, passivation. Full material traceability with MTR and CoC documentation on every order.

Typical applications

Orthopaedic implants, spinal fixation, cardiovascular and dental devices.

Reference tool. Values are typical for the grade and condition stated and vary by supplier, temper and batch — they are reference data, not a specification. The Material Test Report supplied with your order is the governing document for the material actually used. Figures are provided in good faith for early design guidance and are not a substitute for the published standard or your own engineering judgement. Always verify against the controlled standard and your drawing before manufacture. If a feature is critical, tell us at quotation stage and we'll confirm it explicitly.
