Aluminium is a smooth and flexible metal with
abundant benefits that make it an excellent choice for machining.
These include its elevated stability, suppleness,
and lightness. It is non-flammable, lacks magnetic properties, and is reluctant
to corrosion. It’s a perfect material to incorporate on CNC automobiles and can
be used in machining methods including Milling, Drilling, Turning, Punching
& Bending.
History of Aluminium
Aluminium is one of the most universal metals on
Earth, consisting of 8% of the Earth’s core mass. It’s also the third most
widespread chemical element on our planet after oxygen and silicon. Persians
prepared extra-strong pots from clay which also included aluminium oxide and
Greeks and Romans used this material in medicine as an astringent and in dyeing
processes. But the thing is, this material doesn't occur naturally in its
purest form. It wasn’t until the 19th Century with the advancements in
chemistry and the beginning of electricity when this metal was discovered.
Generally present in minerals and compounds like beryl, cryolite, feldspar, and
turquoise. The leading raw material for its production is Bauxite. It is
generally found in topsoil encountered in various tropical and subtropical
regions, and resources are most abundant in Africa, Oceania, and South America.
In the initial stage of metal production, bauxite is
processed into alumina, or aluminium oxide. This material looks like white
granulated powder and then that powder is processed into aluminium at aluminium
smelters by utilizing electrolytic reduction. This widespread is produced in
various shapes and sizes relying on their end-use. They may be spun into aluminium wire rods, binding wires, panes, sheets, foil, or
bars.
Benefits
of using Aluminium
● Lightweight
The metal has a distinct weight of approximately
2.71 g/cm3. It’s somewhere about a third of the weight of steel, which makes it
simple, manageable, and cheaper to transport than most other metals. The
durability of this metal can be adapted by using different types of alloying
elements to provide better benefits that include high strength and easy
formability.
● Corrosion Resistance
This super portable material is also a
corrosion-resistant metal that naturally generates a protective coating. The
coating formed is very thin and is generated when the metal comes in contact
with an oxidizing surrounding. This protective oxide layer protects the surface
of the metal from corrosion. Besides this, getting surface treatment such as
painting anodizing can further endow the overall corrosion resistance of the
metal.
● Electrical and Thermal Conductivity
It is a great conducting element of heat and
electricity. Although it is not as conductive as copper, it's approximately a
third of the weight. An aluminium
binding wire with half the weight of a copper wire would have a similar
amount of electrical resistance. As a result, it is the most chosen equipment
for power transmission lines. Mostly utilized as heat sinks in applications
such as LED lights, electrical products, computer motherboards, etc.
● Reflectivity
Aluminium serves as a good reflector. It is used in
rescue sheets and light fittings because of its power to reflect both light and
heat.
● Odorless and Impermeable
The thickness of the aluminium foil makes it
impermeable with no taste or smell. A non-toxic element, often utilized for
packaging sensitive products that include pharmaceuticals and food.
● Recyclability
The material is 100% recyclable and during its
recycling process, it preserves all of its original properties. It is more
cost-effective to utilize recycled metal than other metals out of the ground.
