We have studied aluminum profiles, so you don’t have to.

This guide will answer all the commonly asked questions about aluminum profiles. So keep reading.

Aluminum Profile - The Ultimate FAQ Guide

What Is An Aluminum Profile?

Aluminum is a chemical element found as a metal in the earth’s crust.

An aluminum profile is an extrusion product made of aluminum alloy formed into various shapes, styles, and sizes.

Aluminum billets are heated until soft enough to be extruded into an aluminum profile. The extrusion press forces the soft aluminum billet through an extrusion die.

This aluminum extrusion process is used to create various extrusions for many uses.

Different shapes of aluminum profiles

                                                            Different shapes of aluminum profiles

How To Make Aluminum Profile?

To make an aluminum profile, you start by preparing the aluminum billet.

This billet is made by casting aluminum alloy into a billet and then sawing the amount you need for the extrusion process.

Next, you raise the temperature of the billet to between 400-500 degrees celsius to make it soft enough for extrusion.

Next, you load the soft billet into the extrusion press. Here a ram will push the soft billet through the die, forming the extruded aluminum profile.

Next, the extruded aluminum profile will be cooled then stretched to reach the desired specification.

The aluminum profile is now ready and can be cut to a specified length.

After the aluminum profile is made, it can now be painted, anodized, or mill finished before it is ready for use.

How To Design Aluminum Profile?

Aluminum profiles can be designed to virtually any shape and design you can imagine.

Different aluminum profile designs exist for various applications. Some designs are made to be easily assembled.

Whereby other designs are made to decrease or eliminate the need for welding.

Follow these tips below when designing your aluminum profile:

  • Maintain uniform metal thickness:

Maintain uniform metal thickness

 Maintain uniform metal thickness

You must specify the metal thickness suitable for your application. Not having enough metal thickness can deform or damage the aluminum profile.

Also, significant differences in the wall thickness of a section can make it more difficult to extrude.

But what if your design has both thin and thick walls?

Then you must ensure to use a radius instead of a sharp edge for the edges where the thick and thin wall meets.

It would help if you also tried to make your aluminum profiles symmetrical. Symmetry in your aluminum profile will make the extrusion process easier.

And symmetry also reduces the risk of damage and deformation on the aluminum profile.

  • Use index marks:

 Index marks

Index marks

Index marks are small lines that run on the surface of the aluminum profile.

These index marks are meant to make punching and drilling easy. It can also make assembly easier.

Using index marks removes the need to create center punches before drilling the aluminum profile.

Designing with index marks also helps us differentiate the inside surface from the outside.

  • Use webs for aluminum profile:

Webs for aluminum profile

   Webs for aluminum profile

Webs can be used on hollow aluminum profiles. By adding a web to a hollow extrusion, you will be able to extrude thinner walls.

This means you can save money by reducing the weight per meter of the aluminum profile.

  • Avoid Sharp Corners by Using Rounded Corners:

 Use round corners

   Use round corners

Round corners are better than straight corners because they are stronger and easier to extrude.

Using round corners over sharp corners can help prevent snapping at the narrowest areas of the void on the aluminum profile.

  • Use metal to metal specifications dimensions and tolerances:

you must measure and specify tolerances and dimensions for your design.

You should specify from one point of the aluminum profile to another point instead of from the hole or centerline.

This is because the dimensions of a hole or an open space cannot be measured during the aluminum extrusion process.

For example, tolerances to a profile with holes in the center, such as an aluminum tubing hole’s center, are more challenging to work with than tolerances across solid metal with no gaps.

  • Use symmetrical designs:

Symmetrical design

   Symmetrical design

It is best to use symmetrical designs when designing aluminum profiles.

Symmetrical designs are better because they can balance load and pressure evenly across the aluminum profile.

Also, symmetrical shapes produce more accurate aluminum profiles.

These symmetrical shapes also reduce the risk of the aluminum profile or die from cracking and breaking.

  • Use fewer hollows:

Fewer hollows

Fewer hollows

Designing your aluminum profile with fewer hollows can make production easier.

Using fewer hollows can also reduce the weight of the aluminum profile, thereby reducing the cost.

Also, using fewer hollows in your design can simplify the die design, which in turn may reduce the cost of the die.

How To Extrude Aluminum Profiles?

You can now start the extrusion process after deciding what design you want to use for the aluminum profile.

Follow the steps below to extrude aluminum profiles:

  • First, you prepare the aluminum billet for extrusion. This is done by cutting and heating the billet until it is soft enough to be extruded.
  • Next, preheat the extrusion press to prevent the hot aluminum billet from causing thermal stress.
  • Next, you could put the soft aluminum billet into the  machine  to start the extrusion process. Use the ram to force the billet through a designed die.

         Then the extruded aluminum profile could be produced into different shapes through the in the different dies opening.

  • Move the extruded aluminum profile to a enough long cooling table, after cooling them, they could be stretched based on customer’s
  • Next, the aluminum profile will go through an “aging” process. This “aging” is done by manipulating the temperature in a controlled environment.

         Aging can also increase the hardness and durability of the metal.

  • After the aluminum profile has been extruded, it is painted, anodized, or taken to the mill for finishing.

How to Join Aluminum Profiles?

To join Aluminum profiles, you can follow the processes below;

  • Trim your profile to the desired length.

It’s critical to make a precise, clean-cut because the quality of your finished connection will be affected by it.

When cutting aluminum, use a decent-grade saw with the right blade. A sufficient supply of high-quality cutting fluid will be required to prevent the aluminum profile and blade from overheating.

Also, make sure your profile piece is secured tightly.

  • Next, tap holes in the aluminum profiles to link them.

Because the core is exactly molded to the correct size for tapping, this is a very straightforward and rapid process.

For slot 8 series profiles, use an M8 tap, and for slot 6 series profiles, use an M6 tap. A flawless thread can be created by using an extrusion tap and the proper cutting paste.

  • Drill a hole for your hex key to fit through it.

Use a drill press or drill guide to correctly locate the hole and avoid damaging the aluminum profile.

A drill press is usually set up for this purpose specifically.

The drill guide is only helpful if you don’t have access to a drill press or when you need to drill a hole on-site.

  • Place a low-profile cap screw and washer in the hole you earlier tapped.

In the slot, place the washer and the cap screw’s head.

Place it in the slot so that the cap screw aligns with the previously bored hole.

  • Next, you tightly join the aluminum profiles. Make sure the two sections of the aluminum profiles are precisely aligned.

What Are Anodized Aluminum Profiles?

Anodizing is a type of electrolytic passivation. A layer of aluminum oxide is formed around the outside surface of the profiles during this process. This process increases durability and attractiveness.

This aluminum oxide is not painted or plated on the surface, but it is totally integrated into the aluminum metal structure, so it will not chip or peel.Anodized aluminum profiles

Any products from LW all pass our quality test. Please don’t worry about their quality.

  • Pricing:

Try to avoid aluminum profile manufacturers with a very low cost for aluminum profiles because a low cost may indicate low quality.

Four factors determine the price of aluminum profiles:

  • the cost of aluminum ingots
  • the cost of extrusion aluminum profile processing
  • the cost of packing materials
  • the cost of freight.

 All of these elements have a clear price tag. If the price of aluminum profiles is lower than the current market pricing, there are three possibilities:

  • First, there might be a low weight per square meter.
  • Second, the aluminum used may be recycled from scrap aluminum.
  • Third, the intensification of material loss could be the third.

As a result, selecting a low-cost aluminum profile manufacturer is not suggested. We will not sacrifice any quality to quote you lower prices.

  • Delivery time:

When choosing an aluminum profile manufacturer, delivery time is also an important aspect to consider.

Bad after-sale service is an indicator of a bad aluminum profile supplier.

LW could provide 24/7 technology, after-sale support.

  • Certifications:

Insurance, certification, registration, and licensing should all be in place for manufacturers.

When an aluminum profile manufacturer is licensed and insured, you can rest assured that the company is following the law.

This ensures that you receive high-quality aluminum profiles.

LW all products pass CE certifications.


What Are The Differences Between Aluminum Profile And Aluminum Alloy?

  • Aluminum Alloy:

An alloy is a combination of different chemical elements. But remember that aluminum is a single chemical element on its own.

An aluminum alloy is made to improve aluminum’s physical and chemical properties to be suitable for aluminum profiles.

Aluminum alloy is usually formed into billets before they are used to make aluminum profiles.

What Are The Factors That Promote The Price Of Aluminum Profile?

The price of aluminum profiles depends on different factors such as type of metal, size, weight, etc.

Below are factors that Influence Aluminum profile Pricing:

  • Mining and Material Processing of Aluminum
  • The Cost of Electricity.
  • Commodity-Specific Events . ( Which are a subset of commodity-specific events.)
  • Trends in the Industry
  • Global Supply and Demand.
  • The global economy.
  • Trade with other countries.

Climate Change and Weather Disturbances Have an Impact on Aluminum Prices.

What Are The Differences Between Aluminum Profile Anodizing And Natural Oxidation?

Anodizing and natural oxidation of aluminum profiles are two different processes.

  • Anodizing:

Anodizing is an electrochemical reaction where the aluminum profile is soaked in an electrolytic bath.

An electric current is added to the bath. As the current flows through the aluminum, it forms an oxide layer on the surface of the aluminum.

This anodic layer is an oxide layer that is stronger and thicker than the natural oxide layer.

Anodized aluminum profiles

  • Natural oxidation:

Natural oxidation is a natural process where an oxide layer forms on the surface of aluminum when it comes in contact with oxygen.

Natural oxidation is a natural process, meaning it happens independently, unlike anodizing that people do.

Anodized oxide has a higher hardness, better heat resistance and insulation, and better corrosion resistance than natural oxidation.

What Are The Differences Between Aircraft Aluminium Profiles And Normal Aluminum Profiles?

There are differences between aircraft aluminum profiles and regular aluminum profiles.

Ordinary aluminum profiles are utilized in our daily manufacturing and lives, whereas aircraft aluminum profiles relate to the seven series aluminum alloy profiles.

  • Mechanical qualities:

A significant difference between aluminum aircraft profiles and standard aluminum profiles is their mechanical qualities.

Because the seven-series aluminum alloy has the maximum hardness of any aluminum alloy, it is ideal for aircraft applications.

The six-series aluminum alloy has a medium hardness and can meet most production and life requirements.

  • The difference in prices:

Another difference between aircraft aluminum profiles and regular aluminum profiles is the price difference.

Aluminum profiles are more difficult to shape as their hardness increases; hence the cost of aircraft aluminum profiles is very high.

The most common six-series aluminum alloy (6063, 6061, and others) has a medium hardness, is easy to extrude, and has a relatively cheap production cost.

  • Weldability:

Another difference is that aviation aluminum profiles cannot be welded together and must be joined using other means.

In contrast, regular aluminum profiles can be welded together, expanding the range of applications for which they can be used.

In summary, aerospace aluminum alloys only have benefits in terms of hardness, and their other features are not as excellent as 6-series aluminum alloys.

Hence they are mainly employed in aviation. The aluminum alloys in the 6-series have a lot of good properties and can be used in a variety of applications.
