What types of Cold Drawn Aluminum are there?

Aluminum is an extremely versatile material used in different fields. Especially for aircraft. It has perfect ductility, which can be made with many metal elements and are made from high-quality materials. Actually, Aluminum also has a range of functions. Aluminum is processed using hot and cold processes.

As a well-known aerospace material, Cold Drawn Aluminum is popular for their resistance to pressure and corrosion. Today, we will focus on the types of Cold Drawn Aluminiums and have a clear overview of it. According to the Aluminum Association, it can be divided into several parts by its grades.

What are the main types of Cold Drawn Aluminum?

From the definition, Cold Drawn Aluminum can be broadly separated into two main categories, which are cast aluminum and wrought aluminum. These 2 categories are judged mainly based on their aluminum content. Whether it exceeds 22% determines the type of Cold Drawn Aluminum.  

In the large manufacturing sector, merely 1 percent of Cold Drawn Aluminum could determine their manufacturing results. 

What are the differences between these different types of Cold Drawn Aluminum?

As mentioned before, the percentage of aluminum decides the types of Cold Drawn Aluminum. Although it may seem like a numerical difference, the percentage determines the quality of Cold Drawn Aluminum. Take wrought aluminum, for example, wrought aluminum are far less resistant to compression and corrosion. If measure against the standards of aerospace metals, it will not suitable and qualified.

To be more precise, Cold Drawn Aluminum can be divided into 8 levels in terms of cracking, corrosion, finishing, and joining. For instance, level 1 Cold Drawn Aluminum has exceptional corrosion resistance and fishing qualities. This aluminum is commercially defined as pure alloyed aluminum 

By contrast, the level 8 Cold Drawn Aluminum is mainly made up of tin and, to a lesser extent, copper and nickel, and cannot be heat treated. The inability to heat sets an upper limit to its ductility. Clearly, this is also its biggest drawback, which is why there are not many commercial uses for this aluminum. This grade of aluminum should never be used in large manufacturing industries, such as automotive manufacturing.

What can we get from Cold Drawn Aluminum?

When mentioning this part, it’s worth pointing out a kind of Cold Drawn Aluminium technology, which is cold drawing. It also can be called cold rolling. According to the definition, Cold drawing has improved the mechanical properties of the metal, which also gives the final product a bright finish. As can be seen, the process of aluminum processing is very complex and requires a host of calculations.

With the increasing variety of Cold Drawn Aluminum, people are increasingly unsure about the type of Aluminum tubes they are buying. Therefore, it is important to check the composition of the elements before you buy
