21. What is the technique through which aluminum rectangular tubing is manufactured?

The ideal manufacturing of aluminum rectangular tubing requires a high degree of accuracy and dedication, which is something that LW takes great delight in achieving. Precision and devotion are required.

Before we begin producing the aluminum rectangular tube, we make certain to double-check the aluminum grade as well as the other necessary components.

The first step is as follows: 

Warming the billet to the proper extrusion temperature after it has been cut to the desired length Depending on the grade of the metal, the temperature might vary between 800- and 925-degrees Fahrenheit.

Second Step: 

Transfer the billet to the loading area and apply a parting agent to prevent the billet from sticking to the aluminum tube extrusion die during the aluminum tube extrusion process. 

The extrusion device will then measure the strain on the billet, allowing it to be placed in the optimal position for extrusion to take place.

Third Step: 

The aluminum billet is then forced against the die in the next step. 

The dies in this example are contained inside the confines of a square aluminum tube, which is exactly what you want.

Liquid nitrogen will be used to prevent the die from overheating and the formation of oxides.

Fourth Step: 

While you are extruding aluminum square tube, take note of the temperature that is leaving.

Keep the velocity of extrusion constant with the aid of this technique.

Keep in mind that the temperature at which different types of aluminum decompose differs. As an illustration:

The 6063 aluminum alloy grade has a minimum temperature of 930° F (or 930 degrees Celsius).

In order for 6061 aluminum alloy grade to function properly, it must be heated to 950° F.

In the fifth step:

The extruded aluminum square tube emerges from the die and is cooled before being cut to the desired length.

22. Aluminum vs. Stainless Steel

Aluminum versus Stainless Steel

 Aluminum versus Stainless Steel

Resistance to Corrosion

Stainless steel is a composite material composed of a variety of distinct components that provide it with unique qualities and strengths.

As a corrosion-resistant agent, chromium is commonly used to protect against corrosion. Additionally, corrosion resistance has been improved because it is non-porous.

Because of the dielectric layer that covers its surface, aluminum has excellent resistance to oxidation and corrosion. 

White pits appear on the metal’s surface when the metal oxidizes, making it more brittle. Corrosion of aluminum can be deadly in some extremely acidic or basic situations.

Conductivity of Heat

The phrase “thermal conductivity” refers to a material’s ability to conduct heat. Aluminum’s thermal conductivity (heat conductivity) is much greater than stainless steel’s.

One of the main reasons it is employed in automotive radiators and air conditioning systems is its superior heat conductivity.


Aluminum is cheaper than stainless steel and is also much simpler to deal with. 

Aluminum is a metal that should be considered if you’re looking for a less expensive alternative to standard stainless steel. Additionally, it is a recyclable metal.


The malleability of aluminum allows it to be easily cut and shaped. Due to stainless steel’s high resistance to wear and abrasion, working with the material may be difficult. 

In terms of manufacturing and dealing with stainless steels, they are more difficult than aluminum.

Welding Ease

Aluminum welding, like stainless steel welding, may be a bit more difficult.

Thermodynamic Characteristics

Steel is significantly more ductile than aluminum, which loses its elasticity at temperatures beyond 400 degrees. 

The ability of electricity to flow like other metals, stainless steel does not effectively carry electricity. 

Since it is such a good conductor of electricity, aluminum may be used in a wide range of products. 

Overhead power lines made of aluminum have great conductivity, are lightweight, and are resistant to corrosion.


While stainless steel is more durable than aluminum, it is also heavier, limiting its usage to the harshest conditions. 

However, due to aluminum’s small weight, it is considerably more often utilized than steel!

Aspects of Food Safety

Stainless steel may be used to store and carry food more safely since it comes into touch with fewer meals and other forms of food. 

It is possible for food to change color, texture, and flavor when exposed to aluminum.

23. What is the impact of aluminum on the environment?

Aluminum Stacked Together

 Aluminum Stacked Together

Because of the ease with which aluminum can be recycled, it is often referred to as one of the most environmentally friendly metals available in the world.

Due to its ability to be melted down and rebuilt again without losing any of its attributes, aluminum may be reused endlessly without losing any of its features. 

When done correctly, aluminum can recycling can save up to 9 tons CO2 per year and is a relatively quick process; 

An aluminum can that you toss out might be back on the market in as little as 6 weeks if done properly.

24. What is the most effective way to store my aluminum rectangular tubing?

Aluminum Being Stored

Aluminum Being Stored

You should store your aluminum rectangular tubing in a place that is both handy and secure for you.

Some things to keep in mind while dealing with aluminum rectangular tube include the following:

Metal should be packed in durable materials to reduce the impact of scratching the aluminum surfaces during transit.

Additionally, bubble foils may be utilized to lessen the effect of people bumping into one another daily. 

This is highly important if you want to make sure that your aluminum is spotless!

Keep your aluminum away from moisture and water to keep it in good condition.

In addition, you should store the aluminum rectangular tubing in a cold, dry location that is free of dampness and moisture.

Because of this, the likelihood of corrosion on the surface of the aluminum rectangular tube will be reduced, which will result in greater durability. 

Despite being corrosion-resistant, it’s still important to make sure that you store the aluminum in a nice and safe place.

Ascertain that they are in a safe location with appropriate weather and temperature conditions.

Also important is to prevent any contact between aluminum and other metals while working with aluminum.

Make sure that the temperature is lukewarm or at the very least room temperature to guarantee that the quality of your metal does not deteriorate too rapidly.

All in all, just make sure that you keep them safe and away from water and moisture, if possible, to ensure maximum longevity!

25. What is the best way to properly maintain my metal rectangular tube?

Aluminum items, such as aluminum rectangular tubes, need regular maintenance in order to guarantee that they last as long as you want them to. This is true of any other item you possess.

When it comes to cleaning your metal, you can simply prevent it deteriorating fast over time by following correct cleaning routines and exercising due attention when it comes to cleaning them.

It’s also critical to ensure that your aluminum is available with a surface treatment option in order to ensure that it lasts as long as possible and is more robust.

This is done to ensure that you receive the most value for your money!

27. How long does aluminum last compared to stainless steel?

Aluminum Breaking

Aluminum Breaking

Aluminized materials may last anywhere from 10 to 100 years if they are exposed to the weather. With this, you’ll obtain a design that is resistant to the elements.

Because of the oxide feature included into aluminum, it can withstand exposure to the elements for an extended period of time. 

The best grade aluminum is accessible for any outdoor project, whether it a roof or anything else.

How aluminum is kept in the outdoors has a significant impact on its life expectancy. Aluminum lasts far longer when it is waterproofed than when it is no

In contrast, steel and other metals are susceptible to rusting and corrosion due to the presence of iron.

The electrical activity between iron and oxygen, which is a critical stage in the rusting cycle and may be increased by a variety of chemicals, can accelerate rusting. 

As a result of the presence of compounds that increase the conductivity of moisture near metal, such as salts and acids, corrosion is sped up significantly.
