NON-FERROUS METALS
ALUMINIUM
Aluminium is one of the most abundant metals on earth and is the third most common element, making up 8% of the earth’s crust. Thanks to the versatility of aluminium, it is one of the most widely used metals after steel.
What is Aluminium?
Pure aluminium is soft, ductile, corrosion resistant and has high electrical conductivity. It is commonly used for foil and conductor cables, but requires alloying with other elements to provide the higher strengths required for other applications. Aluminium is one of the lightest engineering metals with a strength-to-weight ratio superior to steel.
Benefiting from various combinations of advantageous properties such as strength, lightness, corrosion resistance, recyclability and formability, aluminium is one of the metals used in an increasing number of applications today. This product range includes a product range from structural metal materials to the production of thin packaging foils.

What are the Physical Properties of Aluminium?
Density
Aluminium has a density of around one-third that of steel or copper, making it one of the lightest metals commercially. The resulting high strength-to-weight ratio makes it an important structural material for increased payloads or fuel savings, especially for the transportation industry (such as the automotive industry).
Resistance
Aluminium does not have a high tensile strength. However, the strength properties of aluminium can be increased by adding alloying elements such as manganese, silicon, copper and magnesium. Thus, an alloy with properties tailored to specific applications can be produced.
Aluminium is very suitable for cold environments. Its advantage over steel is that its tensile strength increases with decreasing temperature while maintaining its toughness. Steel is a structure that becomes brittle at low temperatures.
Corrosion Resistance
When aluminium is exposed to air, a layer of aluminum oxide forms on its surface almost instantly. This layer shows excellent resistance to corrosion. It is highly resistant to most acids, but less resistant to alkalis.
Thermal Conductivity
The thermal conductivity of aluminium is about three times higher than that of steel. This makes aluminum an important material of choice for both cooling and heating applications such as heat exchangers. This property, coupled with its non-toxicity, is one of the main properties of aluminium, which indicates that it is widely used in kitchen appliances and utensils.
Electrical Conductivity
Along with copper, aluminium has a sufficiently high electrical conductivity for use as an electrical conductor. Although the commonly used conductive alloy (1350) is only about 62% of copper, it is only one-third its overall weight and can therefore conduct twice as much electricity compared to copper of the same weight.
