Aluminum profile refers to the finished-product in different
shape of section, made by aluminum bar by hot melting and extrusion. The making
process of industrial aluminum profile covers casting, extrusion and painting.
Among them, painting mainly consists of anodized, powder coating,
electrophoretic coating, PVDF and transfer paper printing.
aluminum profile has the following properties:
First, the corrosion resistance. The density of aluminum is only 2.7 g/cm3,
which is about one third of the density of steel, copper or brass. In most
conditions, aluminum can display excellent corrosion resistance in many
chemical systems, including air, water and petroleum chemistry.
Second, the electrical conductivity. Due to its good conductivity which is good
for Aluminum Surface Treatment, aluminum profile is often brought into use.
Based on the equal weight, the electrical conductivity of aluminum is twice as
Third, the thermal conductivity. Aluminum alloy is about one half of copper in
thermal conductivity. It is favorable in manufacturing the heat exchangers,
evaporators, heating appliances, cooking utensils as well as the automobile
cylinder head and radiator.
Fourth, the nonferromagnetic. Aluminum profiles
are nonferromagnetic and it is an important feature in the electrical industry.
Spontaneous combustion cannot take place in aluminum, which can improve
security while handling or carrying inflammable and explosive materials.
Fifth, the machinability. The workability of aluminum profiles is
excellent. Among various kinds of wrought and casting aluminum alloy, as well
as the various states after the alloy are manufactured, the change of
machinability is quite big, this requires a special machine tool technology.
Sixth, the recyclability. Aluminum has a high
recyclability, and this property spare no difference between the recycled
aluminum and primary aluminum.
