Nickel Aluminum Bronze Propeller

It s used where higher mechanical properties are required.

Nickel aluminum bronze propeller.

Nickel aluminum bronze nab is a metallic alloy that is widely used for ship valves and propellers among other marine applications. It s used in equipment for the energy markets in aircraft marine and a host of other industrial applications. Kahlenberg repairs propellers of bronze nibral nickel aluminum bronze and stainless steel from 14 inches to over 120 inches in diameter. Maganese nickel aluminum bronze aqualloy vs.

As such it is the purpose of this publication to provide an engineering overview of the properties of the. The nickel aluminium bronze alloys are fairly complex materials and during manufacture require good control of the metal structure by attention to composition and heat treatment. Although the former is more costly by the price per pound the long term cost reduction is appreciable. C630 nickel aluminum bronze is an extruded aluminum bronze that contains nickel and is alloyed for exceptional strength and toughness.

Aluminium bronze is a type of bronze in which aluminium is the main alloying metal added to copper in contrast to standard bronze copper and tin or brass copper and zinc. Applications for nickel aluminum bronze. Stainless steel in marine propellers. Propellers are digitally scanned and records are created including complete geometric propeller data for before and after repair conditions.

Reduced weight of nickel aluminum bronze in conjunction with increased strength of the material allows designing the propeller approximately 15 less in weight than a comparable manganese bze propeller. A variety of aluminium bronzes of differing compositions have found industrial use with most ranging from 5 to 11 aluminium by weight the remaining mass being copper. While displaying a good combination of corrosion resistance and strength nab is still prone to different forms of corrosion such as stagnant sea water corrosion selective phase corrosion and cavitation erosion. The superiority of mn ni al bronze aqualloy has been convincingly demonstrated by its characteristics of service in which has been demonstrated to be the good enough for the work in marine environment.
