Eliche Radice was founded at the beginning of the last century (in 1919) and the company is still owned today by the Radice family. The company structure in Italy is developed over 50,000 m², of which 15,000 m² is covered, and is made up of around 85 employees. For over 80 years Eliche Radice has been designing and making propellers able to satisfy the needs of any kind of boat: fishing, pleasure or fast boats, small or medium tonnage ships, ferries, tug boats, hydrofoils, etc. We are able to make propellers according to your design and design them "fit to measure".
The prerequisites of a propeller depend on three factors: hydro-dynamic efficiency to obtain maximum thrust, structural strength to resist stress, coherence of its characteristics to those of the hull, engine and type of use the boat is bound to.
The range of standard series includes 2, 3, 4 and 5 blade propellers up to a diameter of 4 meters or 4 tons of weight. Eliche Radice software manages a huge volume of constantly updated data based on experimentation with some of the most important research institutes determining all the parameters and propeller designs.

The main material used for the production of brosze propellers are OTMAN and MIBRAL. Its main characteristics are:
OTMAN
- mechanical resistance: R ≥ 535 N/mm.2
- yelding: S ≥ 220 N/mm.2
- elongation: A5 ≥ 25%
MIBRAL
- mechanical resistance: R ≥ 680 N/mm.2
- yelding: S ≥ 245 N/mm.2
- elongation: A5 ≥ 20%
