Classification of metals

From the start the year until now we learnt about Classification, metals, Properties of materials.

Classification 

• Ferrous are metals that contain iron which is therefore magnetic.
• Non Ferrous Metals does not contain Iron which therefore it is not magnetic and do not rust.
• An Alloy is a mixture of metals or a mixture of a metal and other element.

And we learnt that their is many types of metals for example

Iron, Steel, Gold, Bronze, Copper, Brass, Aluminium and etc

We learnt about properties of meterial

Hardness- Ability of a material to resist penetration or scratching.

Ductility- Ability of a material to be drawn into wires.

Brittleness- Ability of material to fracture on receiving shock or blow.

Toughness- Property of a material where it can absorb energy before actual fracture.

Elasticity- A property of a material to bend and to be drawn back to its original shape.

Malleability- A property or ability of a material to be cut or hammered into pieces.

Tenacity- It’s a behavior of metal when it’s broken or deformed.

Density- The degree of compactness of a substance.
