Why choose a PolaStorm QPIM propeller?

An advanced Aerospace Precision Casting (APC) process using Titanium/Strontium/Aluminium alloy, results in a product which is up to 33% stronger than traditional Die and Squeeze Cast aluminium propellers. They are then finished using a robotically applied AkzoNobel* patented, environmentally friendly, anti-corrosion powder coating.
