6061 and 6063 Aluminum Round Tube Details

What is 6061 aluminum round tube?

6061 aluminum round tube is a kind of aluminum alloy round tube mainly composed of aluminum, magnesium and silicon elements. It has high hardness and strength, and can withstand greater pressure and weight. Its tensile strength is up to 310MPa and yield strength is up to 276MPa. In addition, 6061 aluminum round tube has excellent corrosion resistance. It can resist most acidic and alkaline corrosive substances. It is suitable for outdoor piping and chemical transportation piping.

Application of 6061 aluminum round tube

• Aircraft frame
• Battery casing
• Electronic Heat Sinks
• Mechanical Equipment Protective Cases
• Energy transportation pipes
• Food transportation pipeline
• Automotive crash beams

What is 6063 aluminum round tube?

6063 Aluminum Round Tube is a kind of aluminum alloy round tube mainly composed of aluminum and manganese elements. It has good plasticity and processing performance. It is easy to cut, bend, weld and other processing operations, and can be easily made into a variety of shapes and specifications of the tube. 6063 aluminum as a lightweight metal. This makes 6063 aluminum round tube has application advantages in the field of electrical and thermal engineering, etc. 6063 aluminum round tube has smooth surface and high gloss. It can be anodized to get a stylish appearance.

6063 vs 6061 Aluminum Round Tube

Aluminum tubes 6061 and 6063 share many similarities. Examples include corrosion resistance and enhanced strength-to-weight ratios, but their differences make them useful for comparison applications. 6061 aluminum round tube has better strength and hardness. However, it requires heat treatment, which means it is brought to 6061-T6 condition. It differs from 6063 in terms of hardness and ability to carry weight. Therefore 6061 would be more suitable for applications such as electronic housings, and materials for mechanical frames. Aluminum 6063 round tubing would be superior to 6061 for construction projects because it has more options for appearance. The weight ratio is lighter. Therefore, as a construction material it can meet the design requirements. In any case they all have their own advantages and we should choose aluminum tubes according to our project needs.

The following table about the difference between 6061 & 6063 aluminum tubes:

	6061 aluminum round tube	6063  aluminum round tube
Main alloying elements	Silicon (Si), Magnesium (Mg) Aluminum (AL)	Aluminum (AL) Manganese (Mn)
Strength and hardness	Higher	Relatively low, but good plasticity and ductility
Processing performance	Relatively good, but some applications require cutting or heat treatment	Excellent, easy to cut, bend, weld, etc.
Corrosion resistance	Good	Excellent
Electrical and thermal conductivity	Excellent	average in 6xxx series aluminum
Application	Commonly used in the manufacture of aircraft parts, such as engine mounts, fuel lines, etc.	Mainly used in construction projects. It is used as door and window frames, decorative pipes, etc.

What is 6061-T6 Aluminum Tube?

6061-t6 tubing is a heat-treated aluminum product that provides increased strength and structure to cast aluminum parts.The T6 heat-treated condition is achieved by solution treating (heating the alloy to a high temperature to dissolve the alloying elements into the aluminum matrix) followed by artificial aging (holding the alloy at a lower temperature for a certain period of time to allow the alloying elements to precipitate out in a stabilized form), which improves the strength and hardness of the alloy. T6 heat-treated 6061 aluminum tubes have high strength, good corrosion resistance, excellent workability and low density. These characteristics make it widely used in many fields such as aerospace, automobile manufacturing, shipping, construction and electronics.

How to manufacture aluminum round tubes?

This video helps you learn more about extruded aluminum process：

1. Raw material preparation:

Choose high quality raw materials such as aluminum ingot, magnesium ingot, silicon ingot . Mix according to a certain ratio to ensure that the composition of the alloy meets the standard of 6061 or 6063 aluminum alloy.

2. Extrusion molding:

Put the preheated aluminum alloy billet into the heating furnace of the extruder for heating. Make it reach the suitable extrusion temperature. Then, through the pressure of the extruder, the billet will be extruded into tube shape. The extrusion speed and extrusion temperature need to be controlled during the extrusion process to ensure that the size and performance of the extruded aluminum tube meet the requirements.

3. Heat treatment:

The extruded 6061 aluminum tube needs to be heat treated to improve its mechanical properties. Commonly used heat treatment methods include solid solution treatment and aging treatment.

4. Final processing

According to different needs, the aluminum tube is cut, drilled and other processing processes. Finally we are able to obtain aluminum round tubes of different sizes!
