High Precision TC4 Titanium Propeller

  Crevice‑Corrosion‑Resistant 5‑Axis CNC‑Milled TC4 Titanium Thruster Part for CSSC Underwater Propulsion‑Joint Assembly Product Overview Marine thruster system developers often face hidden long‑term reliability risks on titanium connecting interfaces for underwater propulsion equipment. Seawater chloride ions permeate narrow assembly gaps; stagnant brine inside confined mating zones triggers crevice corrosion, gradually breaking down titanium’s passive oxide film. Localised corrosion pits expand under continuous propeller vibration, loosening joint pre‑load and bringing risk of thrust‑unit disassembly during vessel navigation. This TC4 Titanium Marine Propeller Blade delivers gap‑geometry‑optimized connection performance for CSSC‑standard underwater auxiliary propulsion joints. Produced from marine‑certified TC4 Ti‑6Al‑4V titanium forging blank with outer dimensions 370 × 370 × 66 mm and strict ±0.05 mm dimensional tolerance, this machined component controls mating‑surface flatness to…
