Why Aluminium Bronze Makes the Perfect Die Casting Alloy

If you are contemplating the type of metal alloy to choose for your die casting, consider aluminium bronze – a durable copper and aluminium compound. Sometimes, there is an addition of other elements such as silicon, nickel and iron, but the aluminium content is typically 9-12%. The concentration degree of aluminium defines the grade of this alloy. Thus, this allows a wide array of unique shapes with distinctive qualities. 

It Is Corrosion-Resistant 

For many decades now, marine applications rely on this alloy to design significant components such as propellers for tankers and ships. Aluminium bronze is corrosion-resistant and suitable for salty seawater environments. Besides being a tarnish-resistant alloy, it can withstand corrosion when exposed to fluctuating temperatures and adverse chemical environments. Furthermore, it prevents the formation of biological elements on surfaces, perfectly fitting as the choice alloy for die casting over other alloys. 

It's Non-Magnetic and Non-Sparkling

The use of aluminium bronze is widespread, with many industries benefiting from its non-sparkling and non-magnetic qualities. During the manufacture of hand devices, this alloy prevents the possibility of fire for flammable liquid vapours, gases or dust. The tools can produce a certain amount of heat, but with a low-heat spark, there is minimised ignition. This attribute is vital in the oil and gas industries, as well as the mining, transportation and aerospace sectors. 

Its non-magnetic quality makes it the choice alloy for industries that depend on high-powered magnets. For instance, they assist a great deal in hospitals with MRI scanning equipment. Aluminium bronze also mitigates the possibility of galvanic corrosion. This type of corrosion occurs when metal undergoes corrosion while attached to electrical contacts featuring different metals inside a corrosive electrolyte.

It Is Resistant to Wear and Tear

Another excellent property of aluminium bronze is its ability to weld into shapes after a die casting process. Therefore, this means that the product not only produces distinctive features but can also be repaired once complete using welding techniques. Typically, components designed from this alloy do not have to be removed for repairs. Hence, there is littleor no wear and tear. 

Final Thoughts

Aluminium bronze alloys are the best group of metals fit for die casting and welding purposes. They come in four options with several tweaked variants, including nickel aluminium bronze, aluminium silicon bronze, low-nickel aluminium bronze and high-manganese aluminium bronze. The benefits listed above make this alloy ideal for die casting.
