Metal aluminum
Technical Characteristics
The nonferrous metal aluminum is one of the three most common elements in the Earth's crust. It is characterized by a low specific weight and the ability to be easily machined. It has high electric and heat conductivity. Thanks to surface oxide film it is corrosion-resistant. It is paramagnetic metal with white-silver color, very light. Density = 2.7 g/cm³. Brinnel hardness is between 24-32 kgf/mm². Tensile strength is 10-12 kg/mm², and in the alloy it will be 38-42 kg/mm². High ductility is 50% for pure aluminum and 35% for technical aluminum. It has a high thermal conductivity of 203.5 W/(m-K) and an electrical conductivity of 0.037 Ohm - mm2/m, which is about 66% of that of copper. 0.0179 Ohm - mm2/m. It is a small paramagnetic with a linear expansion of 24.58-10-6/°C (t° 20 to 200°C). It is capable of forming alloys with almost all known metals, most commonly with silicon, magnesium, and copper.

Advantages of
This metal is three times lighter than steel. It is corrosion resistant, can be stamped, cut, drilled, has high thermal conductivity and is not toxic. It is used in food industry for making heat-resistant foil and kitchen utensils. However, nowadays it is being replaced by such material as carbon fiber from this sector. Almost the only disadvantage of aluminum is its low strength. To increase its strength, it is alloyed with magnesium and copper.
