Description of aluminum panel
A new aluminum panel with higher strength and bet-
ter workability has been developed by adding a small
amount of metallic elements, including magnesium
(Mg), copper (Cu) and silicon (Si), to aluminum. This
type of aluminum material has equivalent strength to
cold rolled steel sheets.
Advantage of aluminum panel
1. Lighter: The specific gravity of aluminum is 2.7,
which is only one third of general steel panel (7.9).
However, it requires 1.4 times in thickness to
obtain the same rigidity as the steel panel,
resulting in one half in weight.
2. More durable: Aluminum has the property of
creating oxide coating on its surface when it
contacts with the air. This coating prevents it from
being corroded.
3. More heat-conductive: The heat conductivity of
aluminum is twice as high as that of iron. This
means that aluminum absorbs and disperses heat
more quickly, which results in prompt change of its
temperature.
4. More electric-conductive
5. Non-magnetic substance
