When searching for cladding options that meet regulations for use on US projects, professionals in the construction materials industry and designers are increasingly turning to aluminum. This multipurpose metal has several advantages, such as its toughness, flexibility, and lightweight. 

Additionally, it is available in numerous grades, each of which is appropriate for a certain use. For this reason, it’s crucial to think about the grade of aluminum needed for your project. 

The first number in each Series, which ranges from one to seven, denotes the alloying element that has been added to the aluminum. We’ll go into further detail about the most popular Series in the building construction sector, which are 3xxx and 5xx

We’ll also look at all seven alloys and their most popular applications. 

Various Types of Aluminum Grades

The fundamental component of various aluminum grades is the alloy. Finding the appropriate grade of aluminum for your project requires careful consideration of the alloy’s characteristics

Workability, corrosion resistance, heat treatability, electrical conductivity, strength, and flexibility are just a few of the advantages that different alloys can provide. 

There are certain characteristics influence the ideal applications and settings for certain alloys and aluminum ingot molds. An outline of each distinct alloy series is provided below: 

1xxx Series

The 1xxx Series alloys are the most widely used grades of aluminum, including at least 99% pure aluminum. 

They are frequently softer than other alloys and have a great resistance to corrosion. They are perfect for use on outdoor structures or on equipment useful in food processing. 

2xxxx Series

Copper is the primary element in the alloys in the 2xxxx Series. After heat treatment, this gets stronger, but it doesn’t resist corrosion well. Automobile bodywork, screw fittings, airplane structures, and propellers are among the common applications for these alloys. 

3xxx Series

Because of their high manganese concentration, these alloys are renowned for their formability and weldability. They have a higher corrosion resistance than other alloys, but they also have a tendency to be softer. Common applications include building supplies, culinary utensils, gasoline tanks, and radiator cores. 

4xxx Series 

The primary alloying element in the 4xxx Series of alloys is silicon. These alloys are frequently used to make brazing rods and welding wires because of their low melting point.

5xxx Series 

The 5xxx Series of aluminum alloys also referred to as “marine grade” aluminum, are ideal for maritime applications such as boat hulls, storage tanks, and construction materials because they contain magnesium, which offers superior strength and corrosion resistance. 

6xxx Series

The alloys in the 6xxx Series are stronger and can be shaped into intricate shapes because of the combination of silicon and magnesium. These alloys have strong corrosion resistance and are simple to weld. Equipment useful in transportation is one example of a common application. 

7xxx Series

The strongest aluminum alloy is the 7xxx Series, which includes zinc. Its formability is restricted, though, because heat from welding and other fabrication procedures causes the metal to harden. 

Additionally, its exceptional resistance to corrosion makes it a perfect option for construction of structural components.

Why Is Aluminum Such a Precious Material for Construction? 

Aluminum is a strong, lightweight metal that naturally resists corrosion. It is the third most prevalent element in the universe. Aluminum alloys metal are now the material of choice for applications like siding, roofing, gutters, and downspouts.

Moreover, window trim, architectural details, and even structural support for grid shell style architecture, drawbridges, high-rise buildings, and skyscrapers due to their additional properties like high strength-to-weight ratio, durability, machinability, and reflectivity. 

It is feasible to construct structures out of aluminum, such as aluminum alloy 6061 and aluminum ingot satisfactory, that are not feasible to make out of steel, plastic, or wood. Lastly, metal is airtight and soundproof. 

Aluminum extrusions are frequently utilized as window and door frames because of this characteristic. The frames made of aluminum enable an incredibly tight seal. When doors and windows are closed, no air, dust, water, or sound can pass through them. 

As a result, aluminum has solidified its position in the contemporary construction materials sector as a very important building element.

6061 Aluminum: Durability and Resistance to Corrosion 

Building structures and other large-scale construction applications frequently use the 6000 range of aluminum alloys. Aluminum alloy 6061 is an extremely strong, lightweight, and adaptable alloy that is mostly made of silicon and magnesium.

Due to its exceptional corrosion resistance, aluminum alloy 6061 with chromium added is a great choice for roofing and siding applications in construction. 

Aluminum has a high strength-to-weight ratio, meaning that metal weighs just around half as much as steel while offering nearly the same strength. 

The Ratio of Strength to Weight Construction Materials

Aluminum is an extremely adaptable and strong material. Aluminum A7-A8 is a great material option when weight reduction without sacrificing strength because it weighs around one-third that of steel. 

Not only are the lightweight and adaptability useful in construction, but the reduced weight also helps with material loading and transportation. As a result, compared to other metal building materials, this metal has lower transportation costs. In addition, compared to their steel equivalents, aluminum buildings are simpler to assemble or relocate.

Conclusion:

As was previously noted, the 3xxx or 5xxx series alloys are the most commonly utilized grades of aluminum when it comes to the production of solid aluminum plate for the building industry. Because the 3xxx Series is more workable than the 5xxx Series, it is useful more frequently than the two. 

The 3xxx Series is full of strength and resistance to corrosion, the marine grade aluminum 5xxx series is perfect for use in buildings close to the coast as well as on ships and other decorative features on marine vessels. 

Nevertheless, the 3xxx series alloys are more frequently used for building projects because they have lower thermal expansion and are more machinable than the alloys in the other Series. Therefore, to purchase quality construction materials, you may contact us.
