Aluminium extrusion: What you need to know
Nowadays, there are a lot of different construction materials to be used in any structures, such as stainless steel, cement, aluminium extrusion etc. Different materials fit for the different occasions. That you can call is structure design. As a designer, you have to find out the best plan with the irreplaceable materials. That is why the aluminium extrusion jump into all designers’ layouts.
aluminium extrusion is importan building material！
Aluminium extrusion is a light-weight building material. In fact, you can see the material in a lot of buildings, whatever is for construction or for decoration. However, you may not recognize it, because it is common to transform another shape. Thus, let me take you to the world of aluminium extrusion. To get to know it, to pick up it, and to use it!
What is the aluminium extrusion?
Before to understand aluminium extrusion, you should say hello to aluminum at first. Aluminium is a metallic element with the symbol Al. Its elemental substance is a silver white light metal with huge extensibility. It can easily be made into rods, sheets, foils, powders, strips, and filaments. You can think it as a super soft metal. In some humid places, it can have a layer of oxide surface cover, and it can make the Al prevent metal corrosion.
Aluminum powder can burn violently. That is why it can be affected by high temperature quickly. If we do have a Al product, we can see that Al product can be twisted easily after heat bury. Aluminum is the third most abundant metal element in the Earth.That is the reason why it can be applied widely. The most important area to use it is aviation, construction, and automobiles.
Now, we can talk about aluminium extrusion. With all Al’s characteristics, aluminium extrusion has all traits as an aluminum materials. It will be different cross-sectional shapes. To get the different shapes, it will be processed in hot melting and extruding aluminum rods. Whatever in construction or industrial uses, aluminium extrusion is the top reliable material right now.
The processing to make Al be aluminium extrusion
The aluminium extrusion is produced usually includes three steps: casting, extrusion, and coloring. Casting and extrusion is for making different shapes. If you already have product models, you can do it easily. But, coloring is more complex. First, you have think about oxidation. Then you have to finish the painting. In these processes, you will find out the simple methods, such as coating, spraying, or powder coating etc. Finally, if some customers need personality, they might ask for carving on the aluminium extrusion.
The specification and model of aluminium profiles
The common models are 35 series, 40 series, 50 series, 55 series, 65 series, 80 series, and 90 series. These numbers are about the width dimension of the product. 35 means 35 cubic meters. And the customers can pick up the right one for their purposes.
If you see there are 1530, 1590, 1640, 2020, 2040, 200 or 2080 profiles on the aluminium extrusion. That does means the industrial aluminum profiles is 1530 profiles. Among these profiles, 1530 and 2040 profiles are often used in door frames.
Now, we are talking about cross-sectional sizes. There are mostly 1530, 2020, 3030, 4040, 4545, 5050, 6060 aluminium extrusion profiles ,etc.

The traits of aluminium extrusions
Aluminum has low density, but high strength. Its strength is close to, even to exceed steel. It can be produced into various models. Because of its excellent conductivity, thermal conductivity, and corrosion resistance, it is the second widely used material, just less than steel.
The advantages of aluminium extrusions
1. Corrosion resistance
As you known, the density of aluminum is only 2.7g/cm3. The density is around one-third of the density of steel, copper, or brass. That does mean, if under different environmental conditions, even in air, water ,saltwater or petrochemicals, and other chemical situation, aluminium extrusion can show its wonderful corrosion resistance totally.
2. Electrical conductivity
Aluminum have brilliant electrical conductivity. With the same weight, the Al’s conductivity is half of copper’s . Sometimes, it can be instead of the copper.
3, Thermal conductivity
The thermal conductivity of aluminum is approximately 50-60% of copper.That’s why it can be used in heat exchanges, evaporators, heating appliances, cooking utensils, and also cylinder heads and radiators for automobiles.If you ask your parents, they will tell you the first pot or lunch box that they used before are all made with aluminum. They are easily heated.
4, Non magnetic
Aluminum products are non-magnetic. The trait is very important, because it cannot self ignite. In the electrical and electronic industries. It means safety that if loading, unloading, or contacting with flammable and explosive materials.
5. Process-ability
Like what I said before, the aluminium extrusion is soft, so it has excellent processing ability. If you need various aluminum shapes, you only need a stable model and machine. They can be any shapes that you want. Its specific tensile strength, yield strength, ductility, and corresponding work hardening rate govern the variation of allowable deformation.
6. Strong reflectivity
The polished surface of aluminum has a reflectivity of over 80% for white light. On the other hand, aluminium has good reflective properties for infrared, ultraviolet, electromagnetic waves, thermal radiation, etc. Its resistant to nuclear radiation is surprised. Therefore, it is suitable for placing in the roof or surface of walls.
7. Sound absorption
Privacy is more important now, especially for sound. Aluminium can be indoor decoration material and protect your privacy. Also, it can be used in the production of high-end aluminum alloy speakers and it can improve the overall performance of the audio effects.
The price of aluminium extrusions
The aluminium extrusion does not have a accurate price. Usually we will buy it with per ton. However, different models and different purity, even different styles are all means different price. If the aluminium extrusion is not pure enough, or that is the normal style or model, the price will not be high. On the opposite, it is expensive for sure. In particularly, if the customers need special shapes or requirements, the custom version is obviously expensive. Of course, if you can find a good supplier, they might give you a good price with high discount.
How to choose a aluminium extrusion supplier
Above all, we can see it is important to have a good supplier. If you have one, you can get lower price with high quality. Therefore, how to choose a good supplier? There are several standards you have to know.
1. Brand name
If you go on internet to purchase, you will find there are more cheap-price aluminium extrusion products. Some people consider that cheap price means low cost. It does, but it depends on the quality. If you want have high quality products, you have to choose the famous brand manufacturers. For example,Hugh aluminum is the international brand of dunmei Aluminum. They can support high-quality extruded aluminum profile. They can handle all tasks, such as building materials, outdoor railings, handrails and fences. Because the manufacturer exists for 13 years. Hugh Aluminum has strict quality control. We produce and manufacture aluminum products in China market under strict ISO9001 standards.
It currently have 600-1800 tons extrusion Line, 5000 m² Anodized production line, 1000 m² powder coating production line, polishing production process. It is exactly the big scale manufacturer for sure.
2. OEM and ODM requirement
Some people will confuse about OEM and ODM. The truth is if the manufacturer has qualifications, it will have many cooperation manufacturers, and they can help these manufacturers to finish the production process. On the other hand, if it can not support OEM and ODM, it is small scale manufacturer, and it can not guarantee the quality.
3. Design service
In these years, more and more customers need personal style for decoration or building design. These purposes lead to special design service. As a super manufacturer, it should keep the service for special designs. If not ,the manufacturer may lose more customers in the market.
4. On time delivery
Quick pace life means efficiency. The irreplaceable part is delivery. We all know the delivery is developing rapidly. However, in real trades, some projects always are delay because of late delivery time. You have to rest the time for those unpredictable problems. On time delivery is the key for a successful manufacturer. You keep your time, and you customer keep communication with you.
5. Lower price
We just mentioned above, lower price means lower cost. Ex-manufacturer pricing can help you succeed in your local market. If you can keep your high quality with a lower price, you can be more competitive. No one will refuse the low cost.
Conclusion
Aluminium extrusion is more and more popular for today’s decoration or construction. Also, aluminium extrusion develops a lot of different type, such as veneers and honeycombs. They are the sharpest material in construction projects now. That is the reason why there are more and more manufacturers in the market. They all look professional. If you can not distinguish which one is better, you may pay high cost for it.
