Why is aluminum more expensive than iron?

Although the reserves of aluminum in the earth's crust is more than iron, but the production process of aluminum is more complex than iron, aluminum is a more active metal elements, smelting needs to be through the electrolysis method, in the whole production process to consume the cost is higher than iron, so the price of aluminum is higher than iron.

Aluminum profiles can be developed according to the needs of different customers with different specifications of aluminum profiles, this is the profile molding, suitable for any industrial industry, and aluminum profiles when the frame is built is very time-saving and labor-saving, can be assembled according to the needs of the drawings provided by the customer design, and then realize the site quickly assembled to save a lot of manpower and material resources is more greatly save the cost of investment in the enterprise.

And importantly, aluminum profiles can be disassembled and reassembled at will in the later changes, which saves industrial wear and tear, which is also the key to industrial manufacturing production of aluminum profiles can quickly replace the traditional industrial consumables!

On the contrary, iron products, there are more disadvantages, such as easy to rust, short service life, the use of welding when assembled, can not be reused, only as scrap iron recycling, so that the production cost of enterprises has increased.

Although the price of aluminum is higher than iron, but the assembly of aluminum profiles do not need welding, only with corner pieces and bolts and nuts can be assembled into finished products, and can be reused in the later re-modeling, so this calculation, the cost-effectiveness of aluminum profiles is still quite high.

Aluminum has thousands of uses, but in summary there are mainly the following major uses: Aluminum Uses Aluminum for Aerospace is used to make aircraft skins, fuselage frames, beams, rotor blades, propellers, fuel tanks, wall panels, and landing gear struts, as well as ships, rockets forged rings, spaceships wall panels and so on.

Widely used in beverage, food, cosmetics, pharmaceuticals, cigarettes, industrial products and other packaging.

Let's take an example, aluminum cans have the following advantages: unbreakable; light weight; impervious to light.

Wanglaoji, Eight Treasure Porridge, etc. are used in harder tin cans because the packaged material is not under pressure, and it is easy to deform with aluminum cans. And the pressure inside the soda is greater than atmospheric pressure, under the action of pressure, do not have to worry about deformation. And aluminum cans can ensure that the pressure of carbon dioxide in the soda, so that the soda to achieve a better taste effect.
