7005 Aluminum Extrusions FAQ
Here are most of the questions related to 7005 aluminum extrusions. We hope you will find the answer to your question. If not, please leave us a message.
The passage of 7005 aluminum through a die under pressure creates 7005 aluminum extrusions. The die opening can be designed to form different sizes and profiles according to the user’s requirements. Most popular 7005 aluminum extrusions include 7005 aluminum rods, 7005 aluminum tubes, and 7005 aluminum bars. Others are 7005 aluminum channels, 7005 aluminum angles, as well as custom 7005 aluminum extrusion profiles.
7005 aluminum alloy belongs to a group of medium-high strength aluminum alloys, Al-Zn-Mg, meaning that the alloy mainly contains aluminum, zinc, and magnesium. The principle hardening element of this alloy, whose density is 2.6-2.8 g/cm3, is Zinc. With the addition of a smaller percentage of magnesium, the resulting aluminum alloy is heat-treatable and strong. 7005 aluminum alloy is easy to weld, a characteristic that makes the material require very minimal heat treatment.
The Aluminum Association (AA) came up with the 7005 designation, but the alloy has other names. For instance, it is referred to as EN AW-7005 by European codes or A97005 in the European number designations.
If you are looking for the ideal blend of weldability, deformability, low weight, and high strength, aluminum 7005 can be a choice. And where else to get the 7005 extruded aluminum profiles apart from Fonnov Aluminum?
Fonnov Aluminum products exceed all quality standards, so satisfaction is guaranteed. Our manufacturing processes have not only adhered to existing standards but also focused on customer requirements.
You may be wondering whether we have the 7005 aluminum extrusion sizes and shapes that you need for your project. We have 7005 extruded aluminum in the form of cutom shapes, tubes, rods, and bars. CONTACT US for your 7005 aluminum extrusion task.
Stress-corrosion cracking is a potential challenge with this alloy, but it can be avoided with some precaution. Avoid all forms of stresses in the transverse direction of the material at any point where the surface has been sawed or machined.
For 7005 aluminum extrusions intended for use in marine or other strong electrolytes, post-weld aging may be necessary. This prevents selective corrosion attack at the welded heat-affected zone or assemblies where torch brazing has taken place.
In case the environment of using the extrusions is friendly to galvanic corrosion, the 7005 aluminum extrusions should only be fixed on aluminum alloys that portray the same electrolytic solution characteristics. Â On the alternative, the surfaces at the joint should be insulated or protected.
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.
As 7000 series alloys with zinc as the prominent alloying element, these alloys are both understandably very strong. With this feature, they make excellent structures in a wide range of industries. However, the higher zinc content in 7075 aluminum means that 7075 aluminum extrusion is stronger than 7005 aluminum extrusion.
Some extrusion profile design is not workable for 7075 aluminum extrusion, but the shape may be extruded with 7005 aluminum.
The weldability of 7075 aluminum extrusion is worse than 7005 aluminum extrusion.
7005 aluminum extrusions have the following advantages:
- Good welding capability
- Good corrosion resistance
- Good fatigue resistance
- High strength-to-weight ratio
- Good strength at low temperatures
However, 7005 aluminum extrusions can have lower hardness and strength in the weld region.
7005 aluminum has high weldability and can be heat-treated to a high-strength property. It is used to manufacture welding structures requiring high strength and high fracture toughness. 7005 aluminum is commonly used in the manufacture of bike frames, heat exchangers, sport poles, medical equipment parts, pump bodies, etc.
7005 aluminum extrusion has found significant relevance in the bike industry where it is used in the construction of bicycle frames. T6 temper is the most popular one for this industry.
Industrial structures are also extensively built using 7005 aluminum extrusions. These include areas such as support beams and scaffolding.
Even in the construction of aerospace components, trailers, and trucks, 7005 aluminum extrusions are instrumental.
The 7005 aluminum extrusions are perfect for such components in heat exchangers because post-joining solution heat treatment is practically impossible. At the same time, these components should be strong and fracture-resistant.
Yes, 7005 aluminum alloy has good weldability. However, care must be taken when welding this material considering that it is prone to oxidation. You can get strong welds from this aluminum alloy if you apply a welding technique that incorporates oxygen shielding. Argon is a popular oxygen-shielding gas – consider using it when welding 7005 aluminum extrusions.
