Question

Long answer questions Explain the properties of aluminium that makes it a useful metal?​

Answer 1

Answer:

This is because of its particular properties. It has low density, is non-toxic, has a high thermal conductivity, has excellent corrosion resistance and can be easily cast, machined and formed. It is also non-magnetic and non-sparking. It is the second most malleable metal and the sixth most ductile.

Answer 2

Physical Properties of Aluminium:

• Aluminium has a lower density than any other commercial metal except magnesium. Given the right type of surface, aluminium makes an excellent reflector, especially for ultraviolet light.

• Aluminium is an odourless, tasteless, silvery white metal. With increasing silicon and ductile and quite soft. The aluminium crystal has a face centred cubic structure.

• The concentration of the lattice in the less pure metal results from the formation of impurity segregations. Purity also affects most other physical properties.

• Aluminium has a lower density than any other commercial metals except magnesium.

• Aluminium may also be used as a selective cold or hot wall or as a body approximating to the effect of a black body. In the infrared region the reflectivity of aluminium is exceeded only slightly by that of gold and silver.

What are the properties of aluminum?

• This is due to its peculiar properties. It has low density, is non-toxic, has high thermal conductivity, has excellent resistance to corrosion, and can be cast, machined and moulded quickly. It’s non-magnetic and non-sparking as well. It is the second most ductile and the sixth most malleable metal.

Why Aluminium is used in aircraft?

• Since it’s lightweight and solid, aluminium is suitable for aircraft construction. Aluminum is about a third of steel ‘s weight, making it easier for an aeroplane to bear more weight and/or becoming more fuel efficient. In addition, aluminium ‘s high corrosion resistance assures the safety of the aircraft and its passengers.

What is the chemical property of Aluminium?

• Aluminum is a metal which is flexible and lightweight. Due to a thin film of oxidation that occurs rapidly as it is exposed to sunlight, it has a dull silver look. Aluminum is non-toxic , non-magnetic and non-sparking (like metal). Aluminum only has one isotope that exists naturally, aluminium-27, which is not radioactive.

Is aluminum is a conductor?

• Conductors consist of electric current-conducting compounds, or electron flow. Usually, nonmagnetic metals are known to be perfect electricity conductors. A variety of metal conductors are used by the wire and cable industry, but the two most common are copper and aluminium.

What are 3 uses of aluminum?

• Aluminium is maleable and delicate. In a wide range of items, from cans, foils, cooking utensils, window frames, beer kegs and pieces of aircraft, aluminium is included.
