Polastorm is the first company to use the APC casting technique for aluminum propellers. APC casting, also known as Aerospace Precision Casting, is capable of producing aerospace-level products with exceptionally high density and physical strength. Polastorm aluminum propellers prevent blade flex, resulting in better fuel efficiency and performance. This production process eliminates gaps, pockets, and air bubbles inside the propeller material, resulting in a considerably tighter grain structure than a typical die-cast procedure.
Key Features:
-
The props are robotic powder-coated with an anti-corrosive coating powder patented by AkzoNobel.
-
Environmentally friendly.
-
Props are constructed based on OEM blade geometry, with proper cupping and camber applied. Excellent bow lift, acceleration, and peak speed, as well as slip reduction and bite increase.
-
280 MPA tensile and 220 MPA yield strength, which is significantly higher than standard die-casting and squeeze-casting props.
-
Perfect cupping for all series.
-
Hub kit not included.
