Do you know all this knowledge about aluminum tubes?

If you're reading this article, you're probably wondering more about aluminum tubing and whether it fits your specific needs. This article will cover several aspects of aluminum tubing, some of which may be known to some of you. This article will describe various aspects of aluminum tubing in more detail and promote more knowledge about aluminum tubing.

1. What is aluminium tube?

Aluminum tube is a kind of nonferrous metal tube, which refers to the metal tubular material extruded from pure aluminum or aluminum alloy to be hollow along its longitudinal full length. There can be one or more closed through holes with uniform wall thickness and cross section, which are delivered in straight line or roll form. It is widely used in automobile, ship, aerospace, aviation, electrical appliances, agriculture, electromechanical, household and other industries.

2. What are the characteristics of the aluminium tube?


Due to the light weight of aluminum tubes, there are more aluminum tubes per unit weight than steel tubes. Many products benefit from using lighter tubing, especially those that require a certain level of mobility, such as wheelchairs and outdoor furniture.

Strong corrosion resistance

Aluminum tubing is less likely to tarnish than other metal tubing. It is easier to apply paint and other decorations, enhancing its aesthetic appeal.

High thermal conductivity

Aluminum has excellent thermal conductivity, making aluminum tubing ideal for products that rely on temperature control, including refrigerators, solar and air conditioning systems. The light weight and durability of aluminum tubing benefits hydraulic systems, fuel lines, frames and racks.

3. Type of aluminium tube

Aluminum comes in several different alloys. Mixtures of aluminum with magnesium and silicon are solid alloys. This also means that different alloy combinations can form different aluminum tube types. Their functions are different. For example, manufacturers often use aluminum square alloy 6061 for many medium- and high-strength applications because of its increased weldability and excellent corrosion resistance. 6061 aluminum tubing is also easily anodized, making it ideal for heat treating. It is also the cheapest aluminum tubing alloy.

The manufacturer also uses aluminum alloy tube 6063 to achieve a very smooth finish. Since aluminum alloy 6063 is only half that of aluminum alloy 6061, it often appears in value rather than strength applications. The material still has many anodizing capabilities as the oxidizing capabilities of 6061 aluminum alloy.

Heating intensity is often a critical factor when using metal components in fabrication and construction. A metal tube is no exception. In most cases, the two fabrication tasks required for aluminum tubing are bending and joining.

For curved tube, three main factors should be considered:

Modular energy

Certain aluminum alloys, such as the 3xxx, 5xxx, and 6xxx series, are more formable than others, making them a good material for bending. Generally, higher strength alloys also have lower strength.

Thickness and Bend Radius

Aluminum, like other metals, is "work hardened" during bending, which means it becomes stronger and stronger as it is formed. However, if the thickness of the radius is too small, the material is over-machined and more likely to fail.


Elongation is a way of describing the difference between a metal's yield strength and its ultimate tensile strength. Yield strength is the point at which an aluminum alloy can be bent and never returns to its original shape. Tensile strength, on the other hand, is the maximum stress that can be applied to aluminum before it cracks. The greater the difference between these strengths, the more formable the alloy will be.

Connected tube usually means that one tube is connected to another tube, or one end is connected to some type of container. Most commercially produced tubes can be engineered for specific types, shapes and sizes of connections.

4. What is the use of aluminium tube?

Aluminum is used in various industries due to its low density and passivation process. Because when metal parts are used in fabrication and construction, heating intensity is often a critical factor. Metal tubes are no exception. Highest strength refers to the need for a dual fusion of flexibility and strength, aluminum tubes can achieve this application. The aluminum tube is very light, so the volume per unit weight of the aluminum tube is larger than that of the steel.

Lighter piping is preferred for many products, especially those that require movement, such as wheelchairs and outdoor furniture. Additionally, aluminum tubing is well suited for the following industries or product types:

Heat exchanger

The aluminium tube is a strong thermal conductor. The 1000 series of aluminium alloy is the best choice compared to similar conductors. Usually, The tube is a carrier that transferring heat from one place to another. The following products are available in the field of heat exchanger:



-Air conditioning and heating system


-Solar energy

-Steam generator


-Transportation (including aerospace)

The versatility of aluminium tubes is very suitable for vehicles such as automotive, aerospace and rail transportation. As they need a strong but light material assembly to assist completion. This includes:

-Car body



-Fuel tube

-Hydraulic system


-Frame structure or public utilities

You may see a lot of billboards, road sign, etc., on the highway and include the guardrails and other signs. Most of these facilities are made of aluminium tubes from corrosion resistance and low maintenance costs. Other public applications using aluminium tubes also include:

-Building Decoration


-Outdoor structure

-Framework and support

5. Aluminum tube VS other metal tubes

Many industries must use metal tubes, and now more and more industries also use aluminum tubes instead of other traditional metal tubes. What is the difference between aluminum tubes and other metal tubes? What are their respective advantages? See the following analysis, I believe you can choose the appropriate tubeline according to your industry needs.

Aluminum tubing offers the following advantages over other hard metal tubing such as copper and stainless steel:

Material lightweight: There is a big advantage in the fields of ships, aerospace and other fields;

Strong toughness: as high plasticity of the connection material;

Heavy corrosion resistance: longer service life, more cost-effective;

The surface is smooth, it is not easy to rust: strong decoration performance, low maintenance cost;

Heavy thermal conductivity: The aluminium itself has strong thermal conductivity, which can achieve the same performance as other materials being processed.

The disadvantage of aluminium tubes are:

Heating will deform: Ordinary aluminium tubes that are heated to a certain extent will deform. Therefore, aluminium processing is generally carried out according to the use of aluminium tubes, which is not easily deformed;

Material lightweight: Some hard metals will be more advantageous in some areas that require quality strength;

Price cost: The price cost of aluminium can be high than other metals. Because the weight of aluminium is lighter than other metals, and 1 pound aluminium is much more than 1 pound of other metals.
