Material Application for Marine Azimuth Thruster Control Lever

Core objective: to achieve a balance of corrosion resistance, high strength, and operational reliability in harsh marine environments.

1. Main Structural Materials
1）Aluminum alloy (e.g., 6061): lightweight, with enhanced corrosion resistance through hard anodizing or powder coating.
2）Stainless steel (e.g., 316L): high strength and superior corrosion resistance, suitable for demanding marine applications.
-------------------
2. Transmission and Operating Components
1）Main shaft: stainless steel, ensuring precision and durability during reciprocating motion.
2）Transmission gears: copper alloy, wear‑resistant and high‑precision.
3）Internal mechanism: high‑end products feature a stainless steel shaft combined with a brass universal joint to improve load‑carrying capacity.
-------------------
3. Sealing and Protective Materials
1）Seals: EPDM rubber, etc., ensuring IP56/IP67 dust and water ingress protection ratings.
2）Outer sheath: aluminum alloy, protecting internal components.
3）Grip: aluminum alloy with spray‑on rubber coating and nylon elastomer, enhancing comfort and anti‑slip properties.
