Types of Aluminum – Aluminum is one of the most abundant metals on earth, and as such is used quite often, from construction to cooking utensils. This material is known to be lightweight, corrosion resistant, tolerates extreme temperatures very well, and is often more affordable than other materials.
Aluminum has a very diverse type, which is distinguished by its value. Different aluminuium grades, of course, have different properties and different end uses.
The following types of aluminum are distinguished based on the value of aluminum and its uses, including:
Types of Aluminum
1. Aluminum 1100
It is the purest type of aluminum, consisting of 99% aluminum content. This type of aluminum has good workability, corrosion resistance, and has excellent thermal and electrical conductivity, making it a versatile choice for hard forming, welding, chemical storage, electrical transmission applications, and much more.
2. Aluminum 3003
Type 3003 aluminum is the most commonly used choice. This aluminium consists of pure aluminum with the extra of manganese to increase its strength. This type of aluminum 3003 has medium strength, corrosion resistance and good workability, as well as a more economical price, so it is commonly used for cooking utensils, signs, gutters, walls and roofs.
The application of aluminum for roofs and exterior walls is a good choice of material, because it is easy to install, lightweight, has high durability, and is water resistant. This material also cannot be damaged by mold and mildew. That means, more durable.
Experts have confirmed that using aluminum cookware is proven safe and will not leach into food. However, it is best not to cook acidic foods in aluminum pans as this can affect the taste of the food and damage the cookware itself.

3. Aluminum 6061
Aluminum 6061 is an aluminum alloy consisting of magnesium and silicon as the main elements. This type of aluminum 6061 is often named “The Workhorse Aluminum,” because of its resistance to heat and corrosion, and it has much better strength than other types of aluminum.
This makes it very useful for applications in vehicle structure construction, architecture, ship construction and maritime components, as like as scuba tanks and other high pressure gas storage cylinders. This material can also be used in the manufacture of cans for food and beverage packaging.
Although it is said to be corrosion resistant, to further increase its resistance, this type of aluminum needs to be coated with a coating capable of blocking the reaction with air or various elements that can reduce its corrosion resistance.
4. Aluminum 7075
It can be said that this is the most powerful type of aluminum, resistant to pressure and corrosion among other types. This type of aluminum contains zinc as its main element.
Aluminum 7075 is most often used in applications that need a high strenght-to-density ratio, such as aviation transportation applications. It is also commonly used in the production of bicycle components and other sports equipment, and in the manufacture of weapons.
In terms of price, 7075 aluminum clearly has a much more expensive price than other types of aluminum.
