It is also one of the materials that exposes the difference between a general-purpose CNC shop and one built for aerospace work. At Olympus Machining, we routinely produce titanium components for aerospace OEMs, defense contractors, and UAV programs — and the discipline that titanium demands is the same discipline that defines our shop. **Hanover, PA** — This post explains where titanium is used in aircraft and spacecraft, why it is harder to machine than aluminum or stainless steel, and what to look for when sourcing CNC-machined titanium parts. ### At a Glance - Grade 5 titanium (Ti-6Al-4V) accounts for over 70% of all titanium alloy used industrially and is the dominant aerospace alloy - Titanium's low thermal conductivity and chemical reactivity require fundamentally different machining strategies than aluminum or steel - Aerospace titanium parts routinely require tolerances of ±0.001″ (25 μm) or tighter with full material traceability - Olympus Machining is ITAR-registered and produces titanium components for aerospace OEMs, defense contractors, and UAV programs ## Where Titanium Shows Up in Aerospace Titanium and its alloys are used across modern aircraft and spacecraft because they combine high strength, low density (about 60% the weight of steel), and exceptional corrosion resistance. They also retain their strength at elevated temperatures — some titanium alloys remain serviceable above 600 °C, which is why they appear deep in the engine section. Common aerospace applications include: - **Jet engine components** — discs, blades, shafts, and casings in compressor sections, where temperatures and stresses make aluminum unworkable - **Airframe structures** — wing and fuselage components, joints, and bulkhead fittings where strength-to-weight matters more than absolute mass - **Landing gear** — high-strength fittings and structural members that must absorb impact loads - **Fasteners and connectors** — high-load fasteners where steel would be too heavy and aluminum would not be strong enough - **Satellite and spacecraft structures** — corrosion-resistant, dimensionally stable structural elements By a wide margin, the workhorse alloy is **Grade 5 titanium (Ti-6Al-4V)**, which accounts for more than 70% of all titanium alloy used industrially. It is fully heat-treatable, holds its mechanical properties up to roughly 400 °C, and carries the strength-to-weight ratio that makes titanium attractive in the first place. ## Why Titanium Is Harder to Machine Than Aluminum Titanium does not behave like aluminum or like the steels most general machine shops are tuned for. Three properties drive the difference: - **Low thermal conductivity.** Heat generated at the cutting edge stays at the cutting edge. In aluminum, the chip carries heat away. In titanium, the heat concentrates on the tool, and tool-tip temperatures can climb past 1000 °C in milliseconds at aggressive surface speeds. - **Chemical reactivity at high temperature.** Hot titanium will chemically bond with most cutting tool materials, accelerating tool wear and producing built-up edge that ruins surface finish and dimensional accuracy. - **Work-hardening tendency.** Titanium hardens under load almost instantly, so dwelling, light cuts, and rubbing the surface make the next pass worse, not better. The practical consequence is that titanium machining requires a near-inversion of normal logic: slower surface speeds, but aggressive feed per tooth. For Ti-6Al-4V milling with coated carbide, a typical starting window is 25–50 m/min surface speed — five to ten times slower than aluminum — paired with rigid setups, heavy coolant flow directed at the cutting zone, and tooling designed for the alloy. This is why titanium reveals so much about a shop. A facility that runs aluminum at high SFM and tries to apply the same approach to titanium burns through tooling, produces inconsistent finishes, and misses tolerances. A shop with titanium discipline runs slower, monitors tool wear closely, and treats every cycle as a controlled process. ## What "Aerospace Titanium Machining" Actually Requires Beyond the cutting parameters, aerospace titanium parts come with requirements that follow the part long after it leaves the machine: - **Tight tolerances.** Aerospace titanium components routinely call out tolerances of ±0.001″ (25 μm) or tighter, especially on mating surfaces and flight-critical features. - **Material traceability.** Every bar of titanium needs to be tied back to its mill certificate, lot, and heat. This is non-negotiable on flight-critical work and is documented as part of our [Quality Management System (QMS)](/quality-assurance). - **First Article Inspection (FAI).** AS9102-aligned FAI before production release, with full balloon-and-table documentation against the print. - **Process control.** Tool-wear tracking, coolant management, and inspection cadence sufficient to catch drift before it becomes a non-conforming part. - **ITAR controls.** Titanium aerospace work frequently involves ITAR-controlled technical data, which we handle under documented [ITAR-aligned processes](/compliance). ## How Olympus Machining Approaches Titanium Olympus is a [precision CNC milling and turning](/precision-cnc-machining) shop in Hanover, PA. Titanium is a regular part of our workload — engine-adjacent fittings, structural brackets, UAV airframe components, and flight-critical hardware in Ti-6Al-4V and adjacent alloys. Our approach is straightforward: - Disciplined cutting parameters tuned to the specific alloy and feature, not pulled from a generic feeds-and-speeds chart - Rigid setups and short tool overhang to keep deflection out of the tolerance budget - Coolant strategy matched to the operation — flood, through-spindle, or high-pressure as the geometry demands - First article inspection documented against the print before any production lot ships - Traceability from mill cert through final inspection We machine titanium alongside the same [range of aerospace alloys](/materials-machined) — aluminum, stainless steel, Inconel, and engineering plastics — using the same process discipline and quality controls. ## Related Capabilities - [CNC Milling Services](/cnc-milling) — 3-, 4-, and 5-axis milling for complex titanium geometries - [CNC Turning Services](/cnc-turning) — Precision turned titanium components - [Quality Assurance](/quality-assurance) — CMM inspection, FAI, and traceability - [ITAR Compliance](/compliance) — Registered and aligned for defense and aerospace work - [Prototype to Production](/prototype-to-production) — From first article through production volumes - [Materials We Machine](/materials-machined) — Full list of alloys and engineering materials ## Contact Olympus Machining **Olympus Machining LLC** 639 Frederick St, Suite 1 Hanover, PA 17331 **Phone:** [(717) 634-5094](tel:+17176345094) **Website:** [www.olympusmachining.com](/) **Google Business Profile:** [View on Google](https://www.google.com/search?sca_esv=2f4ed381b998a4d8&kgmid=/g/11kr8nzb2c&q=Olympus+Machining+LLC) **Request a Quote:** [Submit a project](/#submission) ### About Olympus Machining Olympus Machining LLC is a [precision CNC machining](/precision-cnc-machining) shop located in Hanover, Pennsylvania.
