With a signature golden colour, this metal is an alloy of bronze, wherein the content of aluminium is far greater than the addition of bronze or even brass. The golden colour is a result of the dilution of the orangish tinge of copper with zinc and the silver of aluminium in the nickel aluminium bronze. Amongst all the bronze alloys, UNS C61400 aluminium bronze is most prized for properties such as their higher strength and corrosion resistance. Not only are the alloys are tarnish-resistant, but  Aluminum Bronze also exhibits a lower rate of corrosion in atmospheric conditions.

The alloy has a lower rate of oxidation at high temperatures.  Furthermore, the MTEK 375 Aluminum Bronze has low reactivity with sulfur containing compounds as well as other products, which are a part of exhaust combustion. The moderate content of copper present in the alloy is what gives the C95900 Aluminum Bronze resistant to corrosion in seawater. The corrosion resistance properties of this particular alloy stem from the inclusion of aluminium in the metal. Aluminium located on the surface of the C95500 Aluminum Bronze component tends to react with naturally occurring atmospheric oxygen. This reaction results in the formation of a thin, yet, tough layer of alumina or as also known as an aluminium oxide layer by manufacturers.  The presence of a newly formed alumina on the surface of C95200 Aluminum Bronze acts as a bar to decay of this copper-based alloy. The addition of tin in the alloy is also known to enhance its corrosion resistance properties.

Another striking property of C95400 Aluminum Bronze is their biostatic effect, which is effective in stopping the growth of micro-organisms on the surface of the alloy. This effect has been attributed to the copper component of the alloy. Copper, in turn, has good anti-microbial as well as bacteriostatic properties, which hinders colonization by marine organisms. Which is why more often than not special Nickel Aluminum Bronze C95800 ranks amongst the most preferred alloys, particularly in comparison to stainless steel or other non-cupric alloys.
