2. WHAT IS METAL?
Metals are elements that are good conductors
of heat and electricity. Most metals are
malleable and ductile, and are generally more
dense than the other pure solid material.
Malleable, means that they can be molded.
Ductile means that the material can be
stretched into a thin wire.

4. CHARACTERISTICS
OF METAL
>Ductility: Metals can be easily
elongated into wires without
breaking.
>Conductivity: Most metals are
excellent conductors of heat and
electricity.
5. CHARACTERISTICS
OF METAL
>Strength: Metals possess high tensile
strength and can withstand heavy
loads.
>Malleability: They can be shaped into
various forms without fracturing.
>Density: Metals generally have higher
densities compared to other materials.
6. TYPES OF METAL
>Ferrous Metals: These contain iron as
the primary constituent, such as iron,
steel, and stainless steel. Ferrous
metals are widely used in construction,
automotive, and manufacturing
industries due to their strength and
durability.
8. TYPES OF METAL
>Non-Ferrous Metals: Examples include
aluminum, copper, brass, and titanium.
Non-ferrous metals are known for their
resistance to corrosion, excellent
conductivity, and lightweight
properties.
10. APPLICATIONS OF
METAL
>Construction: Metal, particularly
steel, is extensively used in building
infrastructure, bridges, skyscrapers,
and other large-scale structures due
to its structural strength and
longevity.
11. APPLICATIONS OF
METAL
>Automotive and Aerospace: Metal plays
a crucial role in the manufacturing of
automobiles and aircraft, providing
strength, rigidity, and lightness to
these vehicles.
12. APPLICATIONS OF
METAL
>Electrical and Electronics: Metals
like copper and aluminum are used in
wiring, electrical components, and PCBs
(Printed Circuit Boards) due to their
excellent electrical conductivity.
13. APPLICATIONS OF
METAL
>Packaging and Consumer Goods: Metal
is used in the production of cans,
containers, appliances, kitchenware,
and decorative items due to its
aesthetic appeal and durability.
14. APPLICATIONS OF
METAL
>Medical and Healthcare: Metals like
titanium and stainless steel find
applications in medical implants,
surgical instruments, and dental
equipment due to their biocompatibility
and corrosion resistance.
15. ENVIRONMENTAL
IMPACT
>Extraction and Production: Metal
extraction from ores and its subsequent
production often require significant
energy consumption and release
greenhouse gases. Proper recycling and
responsible sourcing of metals are
essential to minimize environmental
impact.
16. ENVIRONMENTAL
IMPACT
> Waste and Recycling: Metal recycling
helps reduce energy consumption and
raw material extraction. It also helps
in conservation and sustainability
efforts, as metals can be recycled
indefinitely without losing their
properties.
17. CONCLUSION
>Metal is a fundamental material that has
revolutionized numerous industries worldwide.
Its unique characteristics, wide availability,
and recyclability make it a preferred choice
for various applications. However, responsible
mining, recycling practices, and sustainable
usage are crucial to mitigate the
environmental impact associated with metal
production and consumption.
