Classification of aluminium
What is pure aluminum classified?
Pure aluminum is a soft, silvery-white, ductile and non-magnetic metal that belongs to the boron group and identified by the atomic number 13, because its atoms contain 13 electrons and 13 protons.
What are characteristics of aluminium?
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.
What are the two types of aluminium?
There are two types of aluminum alloys — wrought and cast. Foundry workers form these alloy types in different ways, which significantly impacts their characteristics. This article will help you understand how the various aluminum alloys are named, their physical properties, and their most common applications.
What are 3 physical properties of aluminum?
Physical properties of aluminium are:
- It is a silvery-white metal.
- It has low density and it is light in weight.
- It is malleable and ductile.
- It is a good conductor of heat and electricity.
- The melting point of aluminium is 660∘C.
- It can be polished to produce a shiny attractive appearance.
How many types of aluminium is there?
Aluminum comes in three basic types: 1100, 3003, and 6061. The grade of the aluminum will determine the end-use application and price point. For example, 1100 is a lower-cost material than 6061 but cannot be used for high-temperature applications like cooking utensils or pot lids.
How many grades of aluminum are there?
When working with aluminium there are currently eight series of grades used to categorise the different types of alloy available. An alloy is created by mixing two or more types of metal to offer more desirable features such as greater strength or a higher melting temperature.
What is the most common type of aluminum?
3003 aluminum
3003 aluminum is the best known and most widely used of the common alloys. 3003 aluminum is non-heat treatable. With about 20% more strength than 1100, 3003 is a practical general-purpose aluminum for moderate strength applications.
What are 4 properties of aluminum?
What are the properties of aluminium? 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.
What is the characteristics of aluminium foil?
Foil is a solid metal. It transmits no light and is a total barrier to light including the UV spectrum. Reflects approximately 98% of radiant heat and light. Aluminium is insignificantly magnetic and therefore provides excellent electrical shielding.
What are the characteristic features of aluminium Class 10?
Aluminum Characteristics
- Non-corrosive.
- Easily machined and cast.
- Lightweight yet durable.
- Non-magnetic and non-sparking.
- Good heat and electrical conductor.
Is aluminium strong or weak?
Aluminum is a fairly malleable metal, so you’re unlikely to find it on anyone’s list of strongest metals. However, it’s certainly stronger than many other materials. In fact, aluminum’s balance of malleability and strength is part of what makes it such a useful and versatile material.
What is the chemical properties of aluminium?
Aluminium is a silver type of metal with a tint that is bluish. The melting point is 660°C (1,220°F), and the boiling point is 2,327-2,450°C (4,221-4,442°F). The density of Aluminium is 2.708 grams per cubic centimetre which is both malleable as well as ductile.

Is aluminium magnetic material?
Under normal circumstances, aluminium is not magnetic, mainly because of its crystal structure. It’s referred to as a paramagnetic material along with other metals like Magnesium and Lithium.
Is aluminum a reactive metal?
Aluminium is soft, lightweight and ductile with excellent thermal and electrical conductivity. It is highly reactive, though the metal is protected by a surface layer of inert transparent oxide (Al2O3) that forms rapidly in air, providing excellent corrosion resistance.
What is aluminium made from?
Aluminium is the most abundant metal on earth however, it doesn’t come in its pure form. It has to be extracted from its ore, called bauxite. The process of extracting aluminium is resource-intensive, which makes aluminium among the most expensive metals to produce.
Is aluminium a conductor?
Copper and aluminium are most frequently used as the electrical conductors in electrical cables due to their low resistance and excellent conductivity. These metals are both ductile and relatively resistant to corrosion, but they also have different properties which make them useful for various applications.
Does aluminium rust in water?
Aluminium doesn’t rust. But, it’s essential also to note that aluminium in its pure form, is a highly reactive metal. Technically, pure aluminium dissolves when exposed to water but, it’s reactive nature could also be its greatest asset.
