Propeller Manufacturing. Kruger Sons Propeller has been manufacturing propellers since the 1940's for commercial and individual applications. We have the capability to build propellers up to 14' feet in diameter using manganese bronze, nickel-aluminum-bronze (nibral), or stainless steel, in all styles to any specifications.
Since 1961 we have been manufacturing copper based alloy ingots, including nickel aluminum bronze for ship propellers. The tables below show the most common alloys for this field of application.

Nickel–aluminum bronze is also found to be more resistant to cavitation erosion than high-tensile brass by a factor of two or three, and it is also much more resistant to the impingement type of corrosion, often referred to as wastage, which removes metal from the leading edges and the tips of propeller blades.
Surface-piercing propellers are always dynamically balanced and made from high strength Nickel Aluminium Bronze or Stainless Steel. The Aquapoise 55 is considered the ‘Industry Standard' for medium speed inboard cruisers and it is designed for applications where smoothness and performance are essential.

A bronze propeller is made of bronze or alloys including a high percentage of bronze. These include nickel-aluminum-bronze or bronze-manganese combinations. The propeller is composed of blades affixed to a shaft. They rotate in the same plane, generating sufficient thrust to propel the craft forward. Applications. These propellers are very common.
Nickel aluminium bronze is one of the main alloys used for ship propellers on commercial vessels and cruise liners. Its high resistance to cavitation, coupled with reasonable cost and the ease of repair when damaged, makes it a leading contender for this application (Figures 12

The traditional marine propeller is made of nickel-aluminum-bronze (NAB) alloy because this material has a very high yield strength. However, in recent years, people have found a lot of problems with the NAB propeller in the process of using. Firstly, the NAB propeller has poor anticavitation ability and is prone to fatigue-induced cracking.
Aluminum bronze is the highest strength standard copper based alloy. Concast produces C95400, C95500 and C95900 in standard sizes of rounds, tubes, and rectangles. Aluminum in conjunction with iron and nickel in C95800 acts as a strengthener in these alloys. All of the aluminum bronzes can be heat treated, further increasing tensile strengths.
