Size: Varies based on propeller model and application (typically 10-200 inches in diameter).
Grade: Marine-grade alloys (e.g., NiBrAl, CuNiAl) or stainless steel (AISI 316).
Viscosity: N/A (propellers are solid components; viscosity applies to lubricants used).
Buoyancy: Neutral to slightly negative (depends on material density and design).
Material: Bronze, stainless steel, aluminum, or composite materials (e.g., carbon fiber).
Weight: 5-500 lbs (varies with size and material).
Pitch: Adjustable or fixed (measured in inches/rotation).
Blade Count: 3-6 blades (common for marine applications).
Surface Finish: Polished or coated (anti-fouling, corrosion-resistant).
Certifications: ISO 484, ABS, DNV, or Lloyd’s Register compliant.
