Fixed Blade Bronze Propellers

 

Our Standard series propellers in Manganese Bronze or in Nickel Aluminium Bronze - NiBrAl. The Manganese Bronze is mainly used in less demanding applications that are not under extreme cavitation loading or where high vessel speeds are not a requirement and customers can benefit from the economic advantage of this less expensive material.

We offer the alternative NiBrAl alloy where its superior strength characteristics are required or where vessel performance is a critical factor. Both alloys are easy to repair and have good resistance to erosion and fatigue stress.

PROPELLER RECONDITIONING and RE-PITCHING SERVICE

We can recondition Manganese bronze, Aluminium bronze and Aluminium (outboard and outdrive propellers). All Propellers are Re-welded if required and then polished, balanced, re-tracked and Aluminium Propellers are re-painted. The price depends on the size, material and amount of work required. Bronze propellers can also be re-pitched. It would be wise to contact us prior to sending or delivering a Propeller to check viability and get an estimate of cost. Some propellers can be bent beyond “the point of no return”, and if a propeller has severe electrolysis repair is not possible. As a good guide, if a propeller is held at the boss and a blade is tapped with a metal object, it should “ring”. If a dull thud results it is most likely beyond repair.
