Titanium Propeller

Titanium's lower elastic modulus gives blades a slight engineered flex — this dampens shock loads on the driveshaft during gear shifts or debris impact, reducing wear on transmission bearings and extending drivetrain life.

The hand-polished mirror surface is not only visually striking but also reduces boundary layer drag, improving propulsive efficiency at cruise speeds. Compared to NiBrAl alternatives, users typically see a 10–15% reduction in fuel consumption.

You can choose from natural titanium or anodized finishes in multiple colors — combining functional protection with the premium aesthetic expected on luxury yachts.

Titanium propeller Application

High-Speed Sport Yachts (40-60+ Knots) Thin blade shape breaks planing thresholds quicker and keeps maximum speed with better fuel efficiency. Cavitation resistance is very important at high blade tip speeds.

The reduction of weight decreases the shaft bearing and gearbox stresses and hence increases maintenance intervals in transoceanic deployments.

Racing Sailboat Auxiliaries & Folding Props: Minimal weight prevents stern squat and reduces drag under sail for Custom titanium propeller for yachts. High strength supports folding hinge mechanisms.

But there are actual problems for yacht owners and maritime engineers: increased stern weight, cavitation erosion, structural strain and high fuel consumption. The old bronze or stainless steel propellers just don’t cut it on modern high performance vessels anymore.

Our titanium propellers immediately eliminate these difficulties. The high yield strength of Ti-6Al-4V allows for a smaller blade shape that reduces hydrodynamic drag while retaining structural integrity. A lower rotational mass means a reduced moment of inertia for a quicker throttle response and improved manoeuvrability.

Titanium's natural oxide coating offers excellent resistance to pitting and crevice corrosion in saltwater -- including protection against stray-current corrosion. Coupled with its capacity to withstand cavitation shock waves, your propeller outlives the hull itself.

Each propeller is machined from a high-quality forged titanium billet, then precisely forged to provide a finer grain structure for improved mechanical qualities. From there, 5-axis CNC machining provides complicated blade shapes, internal channels and tight-tolerance connections that ordinary machines can’t produce.

Secondary operations include deburring, hand-polishing, optional anodising or sandblasting. Each blade surface is polished to the nominated roughness prior to the final inspection. It can accept 2D designs and 3D models. OEM/ODM production.

Q: Will a titanium propeller cause galvanic corrosion on my yacht?

A：Titanium is noble on the galvanic series. Proper insulating coupling kits and verified anode protection plans are recommended to protect adjacent metals.

Q: Can a damaged propeller be repaired?

A：Yes. Titanium welding requires an argon-controlled environment to prevent embrittlement. Repair is feasible and can restore full structural strength.

Q: What is the ROI compared to bronze?

A：The upfront cost is higher, but 10–15% fuel savings, reduced bearing wear, and extended service life deliver strong long-term returns.

Q: Why custom instead of stock titanium props?

A：Stock props don't match your hull's specific wake field. The product is optimized to your exact hull geometry, eliminating slip and vibration.
