Why is aluminum more expensive than iron?
The most abundant metal in the earth's crust is aluminum, which accounts for 7.45% of the total mass of the earth's crust.
Although aluminum has more reserves in the earth's crust than iron, the production process of aluminum is much more complicated than iron. Aluminum is a more active metalelement.
Smelting needs to be done by the electrolysis method, and the cost to be consumed in the whole production process is higher than that of iron, so the price of aluminum is higher than that of iron.
Why do most of the aluminum profiles need to be surface treated?
If the aluminum profile is only mill finish, without any surface treatment, the appearance is not beautiful, and it is easy to be corroded in the humid air.
It is difficult to achieve the high decorative and strong weather resistance requirements of the aluminum profile in the building materials.
In order to improve the decorative effect and enhance the corrosion resistance. And tn extend the camnice life aluminum nrofiles are generally curface treated
Why do we choose aluminum materials instead of traditional steel materials?
Due to its excellent structural and functional properties, the surface of aluminum has a dense oxide protective film, which has strong corrosion resistance and can be recycled. And the performance of aluminum and aluminum alloy materials is improved, and now the scope of its application has been continuously expanded.
"Replace wood with aluminum” and “replace steel with aluminum” has become more and more extensive, and the characteristics of light, energy-saving, ecological and recycled aluminum profiles have been further developed.
In general, aluminum profiles are used ithe construction field for their unique
decorative, excellent sound insulation, heat insulation and recyclability, in line with the national green, environmental and energy-saving ideas.
In the future, as the development of aluminum profile industry and process technology becomes more mature, it will expand into more fields and develop in diversified directions.
It will be more widely used in construction, transportation, home appliances, aerospace, machinery and other industries.
