Electrical properties:

You can make the handle of the electrician scissors out

of plastic because it is an electrical insulator.

Thermal properties:

You can make the handle of the pan out of plastic

because it is a thermal insulator.

Acoustic Properties:

You can reduce the sound using mineral wool because

it is an acoustic insulator

Recycling center

When we reuse and recycle we conserve natural

resources and reduce the accumulation of waste

products which damage the environment.

Toxic material

Heavy metals

These materials contaminate the environment (soil, the water and the atmosphere). They can be poisonous for living things.

Biodegradable material

Paper.

Organic material.

Specific plastics.

Metals are materials with many use in the transport

and telecommunication industries, in agriculture,

in construction and in manufacturing machinery.

According to

Pure metals: Metals whose

crystalline structure is

composed of only one

metallic element. For

example: gold, silver, iron,

copper etc.

Metal alloys or alloys: These

are a combination of one or

two metals. One of them

has to be a metal For

example: bronze, tinplate,

steel, cast iron, brass

According to

Ferrous:

Iron (the pure metal), steels, alloy

steels and cast-iron.

Non-ferrous:

Ultralight: Magnesium

Light: Aluminium and titanium.

Heavy: All the other metals are

heavy.

Steel sections

The general properties of metals.

Toughness: The ability to support impacts without

breaking. Metals are tough.

Ductility: The ability to form wires.

Malleability: The ability to form sheets.

Hardness: Scratch resistance. Metals are relatively

hard materials.

Electrical and thermal conductivity: Metals conduct

heat and electricity well.

Metallic shine: Metals characteristically shine after

being recently cut.

Most of them are toxic, recyclable and reusable

Some of them are magnetic. (Iron, steel, cast iron)

Except mercury all metals are solid at room

temperature.

The process of obtaining metals Mining

Obtaining the metals from mines.

Separation of the mineral into ore and gangue

The metal is extracted from the ore in an ironworksthrough physical and chemical processes

Metallurgy

The technology of metals

Technique of obtaining and

producing metals from the

ores that contain them. It

studies its properties too

Siderurgy (ironworks)

(Steel and iron industry)
