FONNOV 6061 Aluminum Extrusions For Our Customers
▹Custom 6061 Aluminum Extrusions
Which aluminum alloy is suitable for my project? This question is important in aluminum extrusion projects.
Aluminium alloy 6061 is a heat-treated durable alloy with good formability, weldability, machinability, and strength. 6061 t6 aluminum is the primary alloy of 6061. It is a high-quality aluminum alloy produced by a heat treatment pre-stretching process. Its power cannot be compared with 2XXX series or 7075 aluminum, but its magnesium and silicon alloy have many characteristics and excellent processing performance. Unique welding characteristics and electroplating properties, excellent corrosion resistance, high toughness, and no deformation after processing, compact and defect-free materials, easy to polish, easy to paint, and unique oxidation effect.
If your aluminum extrusion project does not require high strength or a critical appearance effect, 6061 aluminum will be the most popular and correct choice. 6061 alloy is an alloy with medium and high strength, and this alloy has good machinability, weldability, and forming. In many small extruded components and large extrusion parts, 6061 aluminum is the most commonly used alloy. Because 6061 aluminum has good corrosion resistance and strength characteristics, 6061 aluminum is often referred to as structural aluminum and is suitable for structural applications. As small as LED light aluminum stripes, and as large as railway aluminum parts, 6061 aluminum is widely used.

▹6061 Aluminum Seamless Tubes
Generally, a 6061 aluminum tube (pipe) is produced by hot extruding. Different from the 6061 extruded aluminum tube, the 6061 aluminum seamless tube does not contain any metallurgical welds. In harsh working conditions, seamless aluminum tubes can reduce the possibility of product cracking. Aluminum seamless tubes are widely used in hydrogen fuel vehicles, LNG boats, and vessels, air separation systems.

For Industrial Products
- 6061 aluminum alloy contains magnesium and silicon as its major alloying elements. This combination allows 6061 aluminum to be heat-treated to a higher strength. T6 is the most common temper for 6061 aluminum extrusions. The T6 temper means that the aluminum alloy has been given a solution heat treatment followed by quenching, cooling, and aging. Artificially aging allows the material to achieve the desired precipitation hardening.
- 6061 T6 aluminum extrusions have good mechanical properties and weldability.
- 6061 aluminum tubes, 6061 aluminum rods, and bars are widely used for many machining and fabrication projects. They provide high-moderate strength, excellent corrosion resistance, and superior machinability and weldability. They are the ideal material for many metal projects.
- 6061 aluminum extrusion has a good finish appearance after coating and anodizing. This offers protection and decoration for the finished parts.
- 6061 aluminum extrusions are widely used in engineering and structural applications, like vehicles, railways, shipping vessels, trucks and trailers, electronics, and a variety of industrial projects.
Characters of 6061 Aluminum
The main alloying elements of the aluminum alloy 6061 is magnesium and silicon and form the Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the harmful effect of iron. Sometimes a small amount of copper or zinc is added to increase the strength of the alloy without significantly reducing the corrosion resistance. There is still a tiny amount in the conductive material. Copper can offset the adverse effects of titanium and iron on conductivity. Zirconium or titanium can refine grains and control recrystallized structure. This component improves machinability, lead, and antimony. The Mg2Si is solid-dissolved in aluminum, which gives the alloy an artificial age hardening function.

The 6061-F aluminum alloy helps hydrogen fuel vehicle tubes achieve their expected performance. Since temper F is an “as-fabricated temper”, this large aluminum tube for hydrogen fuel vehicles focuses on the formability of the material. With this temper, creating complex geometries of seamless tubes for hydrogen fuel vehicles is relatively easy. Thus, the alloy supports the manufacture of tubes that are suitable for the storage and distribution of hydrogen fuel. The 6061-F aluminum is easy to fabricate, so it is possible to form a hydrogen fuel system that meets the strict requirements of safety and performance.
Working with renowned customers in vehicle manufacturing, Fonnov is a reputable company that has supplied different clients with the same results – reliable performance. If you need assistance or any form of customization, our specialists are pleased to work with you.
Yes, these alloys are strong enough to perform reliably in hydrogen fuel vehicles. When looking at the strength of an alloy, we look at two parameters: Tensile strength and Yield strength. The yield strength is the value beyond which the alloy will deform permanently. On the other hand, an alloy will break if its tensile strength is exceeded. That said, our tubes manufactured from these alloys are reliably strong for their specific applications in hydrogen fuel vehicles.
Your choice between the two popular alloys depends on the specifics of the project, including the processes you want to subject the material to, the application of the material, and the environment. 7075 aluminum is renowned for its high strength-to-weight ratio and wear resistance. For 6061 aluminum, strength may be less than that of 7075, but the material boasts of machinability and corrosion resistance. For the more regular applications such as automotive and construction, you may want to go with 6061 aluminum. However, 7075 aluminum is more applicable in high-performance and more sensitive applications such as the military and aerospace.
6061 aluminum has other desirable properties for big aluminum extrusions including superior brazability, corrosion resistance, and machinability.
6061 aluminum alloy is popular for large and wide aluminum extrusions, but other alloys could still serve the purpose. The choice of any particular alloy would depend on the strength and other characteristics of the project. Alternatives for large aluminum extrusion profiles include 6063, 7075, 2024, and 5083, etc.
The main alloying elements in 7005 aluminum are zinc and magnesium. In 6061 aluminum, you have magnesium and silicon.
This means that while 7005 aluminum extrusion performs excellently on strength and corrosion resistance, 6061 aluminum extrusion is renowned for machinability, weldability, and strength-to-weight ratio. With a higher zinc content, 7005 aluminum extrusion also tends to be stronger and more expensive. The alloy would also give worse results than aluminum 6061 for machinability because of its higher melting point.
7005 aluminum extrusion is usually applicable in high-stress heavy-duty projects while 6061 does a better job in general industries.
Finally, on cost, the likely scenario is where the 7005 aluminum extrusion costs more.
With the main alloying component in 6061 aluminum being magnesium, this material doesn’t match the tensile and yield strength of 2024 aluminum. It is much easier to work with though, if the project requires a lot of machining and welding.
The name “structural aluminum” for 6061 emanates from the fact that the alloy is highly applicable in structures and products due to its versatility.
The periodic stresses in the aerospace and related industries can be too much for 6061 aluminum. 2024 aluminum works much better in such situations because of its superior strength.
Different aluminum alloy and temper is with different mechanical properties, as well as different requirement in application.
