Nickel Aluminum Bronze Corrosion Resistance

The corrosion resistant property relies on the formation of a copper aluminum oxide film.

Nickel aluminum bronze corrosion resistance. This oxide film provides the following benefits. Aluminum brass bronze sand castings. 04 nickel aluminum bronze alloys are known for their superior corrosion resistance in seawater and many other chemical environments. The corrosion resistant property relies on the formation of a copper aluminum oxide film.

Nickel levels equal or greater than those of iron are believed to increase corrosion resistance the high manganese aluminium bronze alloy cumn11al8fe3ni3 is used primarily as cast propellers in marine environments as it has a higher resistance to erosion corrosion 4. In addition some of the alloys contain iron nickel manganese or silicon. This film is self repairing in media containing even low levels of oxygen. Specifications applications properties techniques corrosion resistance properties and enineering.

In this study a high nickel content as cast nickel aluminum bronze alloy cu 9al 10ni 4fe 1 2 mn all in wt is used as the experimental material. Both cast and wrought aluminium bronzes offer a good combination of mechanical properties and corrosion resistance. Therefore it is necessary to study the effect of hot rolling on the properties of nickel aluminum bronze especially on the corrosion resistance. Nickel aluminum bronze nab is one of the most important group of copper alloys used in marine environments.

Paul foundry 954. Cast nickel aluminium bronze nab finds wide application in naval vessels being of a cu 10 al 5 ni 5 fe formulation with a general corrosion rate of 0 06 mm year 3 and high resistance to cavitation and impingement erosion damage. Aluminium bronzes are copper based alloys in which aluminium 14 wt is the main alloying element. Nickel aluminum bronze alloys are known their superior corrosion resistance in seawater and many other chemical environments.
