2. Aluminium is a silvery-white metal, the 13 element in
the periodic table. One surprising fact about aluminium is
that it's the most widespread metal on Earth, making up
more than 8% of the Earth's core mass. It's also the
third most common chemical element on our planet after
oxygen and silicon.
The most common form of aluminium found in nature is
aluminium sulphates. These are minerals that combine two
sulphuric acids: one based on an alkaline metal (lithium,
sodium, potassium rubidium or caesium) and one based on a
metal from the third group of the periodic table, primarily
aluminium.
Aluminium sulphates are used to this day to clean water,
for cooking, in medicine, in cosmetology, in the chemical
What is aluminium ????.....

4. How aluminium
is made???....
The pure form of aluminium does not
naturally occur in nature, so remained
largely unknown until as recently as 200
years ago. Creating aluminium using
electricity was first developed in 1886 and
is still used to this day.

9. Aluminium alloy materials can be classified into
wrought alloys such as plates, bars, rods, and wire,
and cast/die-cast alloys for sand/ mould casting.
They all have various characteristics and are
designated by four digit JIS numbers*. The alloys
are assigned 1000 class numbers and the lower two
digits denote the associated information. For
example, 99.7% aluminium is A1070 and AL-Mg
alloy is A5052.

23. Why is aluminium finish important and
what types of finishes are there???...
There are 2 main reasons for the importance of finishing choice:
 Reason #1
Finishes can improve corrosion resistance.
Aluminium has a naturally occurring oxide film that protects
it from corrosion. This oxide film is sufficient for many
applications. But in extreme environments, extra protection
may be needed.
 Reason #2
Finishes can enhance the appearance of the aluminium.
Depending on the look you are trying to achieve, you will
need to select the appropriate finish. Maybe you want
something that’s brightly coloured. Maybe you’re trying to
achieve a “mirror” finish. You need to choose a finish that will
give you the look you want to achieve.

25. 1. Mechanical finishes
Aluminium can be buffed, blasted, polished, grinded
or sanded. These finishes can improve surface
quality or prepare the aluminium for other cosmetic
finishes.

26. 2. Pre-treatment
The aluminium is either etched or cleaned
with alkaline or acidic materials. Then a pre-
treatment coating is applied. This coating
enhances powder or paint adhesion and
provides resistance against corrosion.

27. 3. Chemical Finishes
An extrusion can either be etched or bright
dipped. Etching provides a silver-white, or
“frosted” finish. Bright dipping gives the
aluminium a specular or “mirror” finish. For bright
dipping, a special dip solution is applied (Usually a
combination of hot phosphoric and nitric acids).

28. 4. Anodizing
This electrochemical process provides additional
protection aside from the natural oxide film. A
durable, porous anodic oxide layer is formed on
the surface of the aluminium. Anodized aluminium
will also accept vibrant colours. You can anodize
any kind of aluminium alloy.

29. 5. Liquid Coatings
These coatings come in many colours and
provide a uniform film thickness. Liquid coatings
generally contain volatile organic compounds
(VOCs). They are driven off during the curing or
baking process. When the VOCs are gone the
volume solids form a film on the extrusion.

30. 6. Powder Coatings
Powder coatings leave behind a film that can meet
stringent performance criteria. At the same time,
they do not contain VOCs. This is ideal for meeting
environmental regulations on VOCs. The product is
applied as a solid on the extrusion. While going
through the oven process, solid particles fuse
together to form the film.
