Why aluminum is rust-resistant? (Rust & Corrosion)
Rust & Corrosion
Aluminum is rust-resistant, There are different types of materials that rust-resist. Aluminum is one of the famous and useful metals in different industries. It doesn’t degrade because of oxidation. Rust just happens in iron and other metals that contain iron, for instance, steel is an easy target for rust because it includes iron. As you know that doesn’t contain iron; on the other side, it has a very thin aluminum oxide film (Al2O3) that protects the metal in front of oxidation and rust.
Even though it doesn’t rust, that suffers from corrosion. Most palladium metal Works customers think that rust and corrosion are the same but as it is mentioned, aluminum is fully resistant to rust although corrosion in depending on its type.
Some alloys, like 5xxx and 3xxx, have the best corrosion resistance than others which we use in our railing, gate, fence, stairs, and other manufacturers.
Aluminum is recyclable, The environment is important to us. The high durability of our products contributes to the environment.
For more protection, we are able to powder coat and anodize to guarantee our product from any corrosion.
Why does not aluminum rust?
It has made significant progress as a material over the last 50 years due to its special properties and has been able to emerge and is being used more and more in the construction industry.
Extruded, rolled, and cast aluminum for the manufacture of aluminum door and window frames, ceilings, false ceilings, fences, fence, And panels, prefabricated buildings, and scaffolding are in increasing use.

A) Lightness and flexibility:
Aluminum is a metal with a weight of about one-third of the weight of steel, this capability along with very high flexibility has made both metals unique. This property, in addition to significantly reducing the static load of our structure (especially aluminum doors and windows), do not work during natural hazards, including earthquakes.
B) Ratio of strength to weight:
The density of aluminum is 7.2 grams per cubic meter, which is about one-third the density of steel. The strength of aluminum can be greatly increased by up to 15 rockets by using special profile shapes and heat treatment.
This amount is also higher than the hardness of iron metal (7/2) Rockwell. This low density makes the cost of shipping and handling aluminum products cheaper and easier and most of the artifacts can be manually moved and the need for cranes and lifting and so on. So their installation is also very fast, accurate and inexpensive Be.
C. Relatively high melting temperature:
Aluminum melts at 1100 degrees Fahrenheit and is ignited as a material. Because aluminum does not burn and is non-flammable.
In large fires, it takes a long time to reach 1200 degrees Fahrenheit, and this causes it to absorb a large amount of fire energy. Roofs of industrial and exterior walls made of panels of thin aluminum are designed in a major fire melted a result, the building opened, heat and smoke released and allowed to leave the find and thus access for fire fighting easier The temperature applied to the plant decreases and the main structure remains healthy.
The important point is that aluminum has a much higher quality when heated and even melted compared to wooden or UPVC windows. They do not produce any dangerous or toxic gas or smoke.
D) Physical and chemical durability:
Aluminum is 23.2 times harder than PVC and 2.7 times harder than wood. Therefore, aluminum doors and fences, and structures do not show any problem with abrasion and stress due to the movement of the structure and do not deform against the applied loads. Unlike most aluminum building materials, it has a long and unlimited life.
It was installed in the dome of the Roman church and has been around for nearly two centuries and has not changed. Aluminum does not absorb moisture, does not swell, does not crack, does not rust, and does not crack or tear. It does not shrink and is not perishable and does not need any coating in the face of UV rays.
Its alloys are limited and contain elements such as manganese, magnesium, and silicon. The oxide layer formed is thin, solid, and non-porous and plays a role in the coating.
Why does not aluminum rust?
Pollutants such as ammonium, carbon monoxide, and carbon dioxide have almost no effect on aluminum. The low effect of sodium chloride and other salts on aluminum is also due to the use of this metal in marine structures and coastal areas. The best blocking materials are moisture or aluminum (like foil) or a combination of aluminum and sheet metal: aluminum.
Metal aluminum is anodized, ie as an anode. By applying an electric current, an oxide layer on its surface that the thickness of the layer is higher than the layer of natural oxide. In addition to aluminum dyeability is very high
The unique variety of colors along with the ability to wash very easily and as a result of its constant cleaning and easy maintenance, we are the result of these properties.
