Bronze Propellers

About

O ur Standard series Propellers are cast in Manganese Bronze or in Nickel Aluminium Bronze - (NiBrAl). 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. Please contact us if you require a propeller to be bored to your specification, or you would like us to calculate propeller size, pitch and blade area. WHEN ORDERING PROPELLERS, PLEASE STATE: Blade type – Diameter – Pitch – Rotation – Accurate taper dimension – Keyway size.

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
