Machining Grade 9 (Ti-3Al-2.5V)

Machinability is rated moderate — machinable without drama, but it rewards proper tooling, feeds and speeds — cycle times sit above the easy-cutting grades. 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 9 (Ti-3Al-2.5V) is ±0.010mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: As machined, anodise. Full material traceability with MTR and CoC documentation on every order.

Typical applications

Aerospace hydraulic tubing, sports equipment, high-performance motorsport.

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.
