Metals used in School
DIFFERENT TYPES OF METALS -generally used in schools
Metals fall into 2 groups; those which contain IRON and those that DO NOT. The word Ferrous means iron, so obviously ferrous metals, such as Mild Steel, contain iron.
The bottle-opener you will make in Year 7 will be produced
from a piece of mild steel. it is a strong and hard metal and that is
why it Is used to make car-bodies, washing machines and bridges. etc.
All metals can be made softer by heating them to a bright-red
colour and allowing them to cool-down naturally. This is called annealing.
Other non-ferrous metals you may have heard of are; brass, lead, bronze, tin and aluminium.
Metals are chosen depending on the different advantages
they offer; such as strength. hardness and non-corrosive.
