Titanium Grade Selection
Choosing the correct titanium grade ensures your parts meet the strength, corrosion resistance, and biocompatibility requirements of your application.
| Grade | Key Properties | Best Applications |
|---|---|---|
| Grade 2 (CP Ti) | Pure titanium, excellent corrosion resistance | Chemical processing, medical implants, marine |
| Grade 5 (Ti-6Al-4V) | Highest strength, standard aerospace alloy | Aerospace, defence, high-performance engineering |
| Grade 23 (Ti-6Al-4V ELI) | Extra Low Interstitial, biocompatible | Implants, surgical instruments, medical devices |
| Grade 9 (Ti-3Al-2.5V) | Good strength-to-weight, formable | Hydraulic tubing, aircraft parts, bicycle frames |

Titanium Parts FAQ
What titanium grades are available for machined parts in Australia?
We supply titanium parts in all standard grades: Grade 1 (purest, most ductile), Grade 2 (commercially pure — most common, balance of strength and corrosion resistance), Grade 4 (highest strength of CP grades), Grade 5 / Ti-6Al-4V (most widely used titanium alloy — aerospace workhorse, 6% aluminium, 4% vanadium for high strength), Grade 9 / Ti-3Al-2.5V (tube and tubing applications), and Grade 23 / Ti-6Al-4V ELI (Extra Low Interstitial — implant grade, biocompatible). Material certification provided with all orders.
Why is titanium so expensive to machine?
Titanium is difficult to machine for several reasons: low thermal conductivity means heat concentrates at the cutting edge rather than dissipating into chips, causing rapid tool wear; high chemical reactivity means titanium bonds with cutting tool materials at elevated temperatures (built-up edge); and titanium's springback requires higher cutting forces. Machining cycle times are 5–10× longer than aluminium for equivalent parts. Carbide tooling, aggressive coolant, and conservative speeds are required. Despite higher machining costs, titanium's exceptional strength-to-weight ratio and corrosion resistance often justify the investment.
What is Ti-6Al-4V and why is it used for aerospace parts in Australia?
Ti-6Al-4V (also called Grade 5 titanium) is an alpha-beta titanium alloy containing 6% aluminium and 4% vanadium. It is the most widely used titanium alloy globally, accounting for over 50% of all titanium use. Properties: density of 4.43 g/cm³ (57% of steel), ultimate tensile strength of 950 MPa, excellent fatigue resistance, and usable up to 300°C. For aerospace applications in Australia — RAAF platforms, defence contractors, civilian MRO — Ti-6Al-4V is specified for airframe brackets, fasteners, engine mounts, hydraulic fittings, and structural components where weight reduction and strength are both critical.
What tolerances can be held on titanium machined parts?
Standard CNC machining of titanium achieves ±0.05mm on general features. High-precision machining holds ±0.01mm. For tight-tolerance aerospace and medical components, grinding after rough machining achieves ±0.005mm or better. Titanium's springback requires careful toolpath strategy and fixturing. Specify all critical tolerances on your 2D drawing — our DFM review will identify any concerns before quoting. CMM inspection reports are available on request.
Can titanium parts be anodised or surface treated in Australia?
Titanium can be anodised (Type II titanium anodising) to produce decorative or functional oxide layers in a range of colours — without any pigment, purely through oxide thickness variation. Colours range from gold and bronze through purple, blue, and green depending on voltage. Titanium anodising adds corrosion resistance and identification colour-coding. Other treatments available: bead blasting (matte finish), electropolishing (for medical grade), and passivation. Painting and powder coating are not typically used on titanium. Specify finish requirements on your drawing.
Is there a minimum order for titanium machined parts?
No minimum order. We supply single-off prototype titanium parts as readily as production runs. Single aerospace brackets, medical implant prototypes, and one-off replacement parts are all within scope. Per-unit pricing for single-off titanium parts is higher due to setup amortisation — increasing quantity from 1 to 5 or 10 typically reduces per-unit cost by 30–60%. Quote includes free DFM feedback.
