The versatility of aluminum is well documented; from its lightweight to affordability, ease of machining, and environmental friendliness, aluminum has been successfully used in many industries. Industrial aluminum profiles refer to the aluminum material suitable for use as a main component in industrial aluminum extrusion processes.

In the extrusion process, the chosen aluminum bar is extruded by melting the material forced into a particular die with the desired section shape. The mechanical and functional properties of the finished product depend on the selected aluminum profile. What factors then make one aluminum profile more suitable than another? These seven factors and considerations are used to highlight the differences:

1. Strength

Strength or durability refers to the ability of the aluminum profile to withstand pressure, damage, wear and tear that arises from the day-to-day use of the part as intended. It also refers to the ability of the part to withstand pressure and heat treatment. The maximum tensile strength is the amount of stretch or pulling the profile can take before its mechanical properties are permanently altered.

Generally, pure aluminum has the lowest strength, while the heat-treated alloy series of and are progressively higher in strength. The and offer medium to high mechanical strength.

2. Hardness

Hardness is different from the aluminum profile strength and is a factor in the aluminum profile&#;s chemical composition. The state of the aluminum profile also has a profound influence on the hardness of the profile.

The hardness matrix decreases from the 7 to 2,4,6,5,3 and 1 series in that order.

3. Corrosion Resistance

Corrosion resistance speaks to the ability of an aluminum profile to withstand the chemical changes to its structure arising from exposure to chemical and rust conditions.

In this case, the best corrosion resistance is seen in the 1 series. Next is the 5 series, then comes the 3, 6, 2 and 7 series in that order. In clearer terms, the Alloys , , and have excellent to very good mechanical properties, the and have decent corrosion resistance, while the 2 series is generally poor.

4. Weldability

Weldability refers to how easily an aluminum profile can be welded. The weldability of most aluminum profiles is generally very good. However, profiles of alloys , , and are inferior. Alloys and have excellent welding performances. The 5 series of aluminum profiles are particularly designed for welding.

5. Machinability

Machinability performance entails the ease of forming and machining an aluminum profile. This includes cutting, forming, and turning in some instances. Generally, the machinability of each aluminum profile may be affected by heat treatment or annealing. Annealed parts are very machinable and formable, while heat-treated aluminum materials are more challenging to machine. The alloys of are excellent for machining, by the , , and alloys.

6. Finishing

Aluminum profiles may be coated, anodized, polished and more to obtain the desired feel, look and finish. Depending on the end-use and environmental conditions where the part may be deployed, the aluminum profile for extrusion may need specific chemical and surface treatments to deliver on performance expectations.

7. End-use

By research and experience, certain aluminum profiles are more suitable for some industries than others. For instance, the Aluminium alloy and are broadly used in general machining and metal spinning, while the and are deployed in metal spinning and aerospace industries respectively.

Aluminum alloys are widely used to fabricate food and chemical equipment, while the alloys are applied in marine fabrications. Alloys and are best suited for structural and architectural applications.

Aluminium profile has become extremely useful for both residential and commercial real estate owners. It has been gaining popularity day by day because of its strong commonality, long service life, convenient assembly and disassembly, environmental protection, and time-saving benefits. Aluminium profiles can be used for construction projects, doors, home decorations, windows, and furniture.

Most of the people remained confused about the selection of aluminium profile suppliers. It&#;s because hundreds of suppliers are available in the market and it becomes difficult to choose the trust-worthy supplier among them as every aluminium profile supplier claims to be the most qualified. But nothing to worry, as we are going to discuss three golden rules to help you select the competent aluminium profile supplier. Let&#;s have a look at these golden rules. 

Never select a very cheap aluminium profile supplier

The first rule is to avoid choosing a very cheap aluminium profile supplier. The price of aluminium profiles depends on four elements i.e. aluminium ingots cost, extrusion aluminium profile processing cost, packaging material cost, and freight cost. The cost of all these elements is very transparent. So, if the price of aluminium profiles is lower than the existing market price, then it can be due to three reasons. The first possible reason can be less weight per meter. The second reason can be the recycling of waste aluminium, and the third possibility can be the intensification of material loss. Hence, it is not recommended to choose very cheap aluminium profile manufacturers. 

Never choose a supplier who just knows sales materials

We never suggest you to select an aluminium profile supplier who just knows about sales materials. There are a few companies that only make some items, hire many wiring workers, do lots of online promotion, and then the trade begins. These companies often hurt the buyers as the wiring workers don&#;t have much knowledge about the actual product and its usage. When these companies are asked about the usage of the product and the best type of connection in different sites, they have no correct answer. They just suggest the low-priced material and the cheapest method of connection, which ultimately causes a high labor cost and trouble for later modification.

Choose aluminum profile suppliers with production factory

It is another key principle in choosing the best aluminium profile supplier. Prefer selecting an experienced supplier who has a good understanding of product performance and quality, such as Anhui Shengxin Aluminum Co., Ltd. that has more than 20 years of experience in this field. All of their workers are well experienced and skilled, and thus produces high-quality aluminium profiles. So, you don&#;t need to worry about the quality of aluminium profiles if you buy from Shengxin Aluminium. Their aluminium profiles have been well received from their customers all over the world.
