Physical Properties Of Aluminium As Shared By Aluminium Suppliers In Australia

As a premium aluminium supplier in Australia, we know the physical properties of this invaluable metal inside out and back to front. These properties are what makes aluminium so popular for use in a variety of applications, from structural to packaging. We have shared these properties in a little more detail here to help you reach a decision about using it in your own application.

  • Corrosion Resistance
    When exposed to air, a layer of aluminium oxide will form on the surface almost instantaneously. This layer has excellent resistance to corrosion, which is why it is often selected for external applications. The metal is also fairly resistant to acids but is less resistant to alkalis.
  • Density
    Aluminium has a density that is around a third of that of steel and copper, which makes it one of the most lightweight metals that is commercially available. Its high strength to weight ratio also makes it a valuable structural material, allowing for increased payloads or fuel savings.
  • Electrical Conductivity
    This metal has a conductivity that is high enough for it to be used as an electrical conductor. It can actually conduct twice as much electricity when compared with a supply of copper that is of the same weight (not to mention that it’s more affordable).
  • Reflectivity
    Aluminium is actually an excellent reflector of ultraviolet and infrared rays. It has a visible light reflectivity of around 80%, which makes it popular for use in light fixtures. These same properties make the metal ideal for use as an insulating material.
  • Strength
    In it’s purest form, this metal doesn’t have a high tensile strength. With the addition of alloying elements (such as manganese), however, its strength properties are increased. Its tensile strength also increases with decreasing temperature, making it suited to cold environments.
  • Thermal Conductivity
    The thermal conductivity of this metal is around three times greater than that of steel. This makes aluminium a valuable material in both heating and cooling applications. As it’s also non-toxic, it’s used extensively in the manufacture of cooking utensils and other kitchenware.

We hope that the above information has taught you a little more about the physical properties of aluminium. As you can see, there are a variety of reasons why this metal is so popular for many different applications – all you really need to do is take your pick. If you require more information or assistance, don’t hesitate to speak with your chosen aluminium supplier in Australia.
