Which aluminum type is best for making a keyboard case?

Aluminum is a chemical element gotten from ingenious rocks. Aluminum also has alloys that make it endearing in the use of a keyboard case. It means that two or more metals are combined to form the material. For ease of understanding, let me classify the type of aluminum material by its physical properties.  Some of the most widely-used types of Aluminum are:

6061 Aluminum

You can call the 6061 Aluminum a jack of all trades. 6061 aluminum is always in the market. It makes it a popular choice for producers. The 6061 aluminum is a better option for making keyboard cases. It has excellent strength, highly anti-corrosive, high weldability and machineability. 6061 aluminum is preferred where strength and corrosion resistance is a much-needed factor. Their good surface finishing also makes them a better option for consumers.

6063 Aluminum

This type is almost like the 6061 type. While this is almost like the 6061, it is more preferred for architectural uses. They are also for exterior and interior designs.

5052 Aluminum

The 5052 has an excellent quality too. Just like the 6061, it has better finishing and corrosion resistance. The drawback of this type of Aluminum is that it is difficult to machine. A heat process can not treat this type of Aluminum.

Other types of aluminum such as 5053, 7075, 6053, can be used to make a keyboard case also, but it is not common.

How to make an aluminum keyboard case?

After finishing the keyboard case design, one of the important things is producing it. Otherwise, you never know what your keyboard looks like, how cool it is to use, right?

So let me talk about the different ways of making aluminum keyboard cases. For different quantities, we will have a different production method.

For Prototypes or small volume production

For the keyboard case that has just been designed, has not been tested, and has not been accepted by the market. We recommend making prototypes to test first, such as check match with the keyboard PCB installation. This can reduce the production risks caused by design errors. Imagine if there are 1,000 failed keyboard cases in your warehouse, how much money and energy pressure will it bring you?

For small batches, we will use 3D printing and CNC machining methods to produce, this is the fastest and cheapest way.

3D printing is a very popular manufacturing process recently, and it is an ideal choice for parts with complex internal structures. However, CNC is still the most mainstream processing method for aluminum keyboard cases because it is fast, precise and stable.

According to our experience in machining more than 190 different kinds of aluminum keyboard cases, it will cost about $35-$68. Of course, it depends on your design.

For mass production

When your keyboard case has passed the test, and ready to hot sell in the market. So how to reduce costs becomes your next consideration.

Using die casting technology can greatly reduce your costs. Of course, this will require MOQ, because manufacturing a die-casting mold is also a big expense.

Die Casting can be produced in stable mass production, even if the internal space is more complicated. After die casting, CNC machining is needed for secondary processing, such as deburring, threaded hole drilling, and so on.

After that, anodizing or other surface treatments are carried out.

If you are not professional in production, it doesn’t matter, DEK can serve you one-stop. You design, we produce. We are a professional company to help you more worry-free.

Can the aluminum keyboard case be anodized?

Yes, your keyboard can be anodized. The process of anodization gives your keyboard case a better surface finishing. Anodizing is a method employed to transform your aluminum keyboard case. Anodizing your keyboard makes the outer surface stronger and protects it from peeling off. It also helps your keyboard fight oxidation, which protects it from rust.

What colors does the anodized keyboard case have?

The anodizing color ranges from brown to blue, red, purple, green, black, grey, gold, etc. Therefore, depending on your preference, you can have the color you desire. Note that your Anodized Aluminum case color is dependent on proper control of the process. Thus, depending on the control process, you can have pale yellow, orange, pink, lime green, dark green, etc.

For example:

Other ways to add colors to your aluminum keyboard case

There are possible ways to add color, but the colors aren’t very predictable. We have two broad ways to add color to an aluminum keyboard viz:

Electrolytic Coloring

In this method, you immerse the part you want to add color into the solution. The solution contains corresponding metallic salt. The essence of the salt is to fill the holes on the aluminum surface. After filling the gaps, they provide a strong coating. The coating fights ultra-violet fading of the bronze and black color.

The resulting color is not only a function of the color of the die. The color also depends on the depth of the pore. It depends on how much light shines off the surface of the Aluminum.

Conversely, it becomes difficult to predict the added color. The anodizing process is the least controlled when trying to add more colors. Also, in anodized Aluminum keyboard case, not stains can be reproduced.

Dip Coloring Method

This process involves placing the desired part in a die tank. In this process, the die is absorbed into the pores. As the die is absorbed, the surface goes through boiled de-ionized water. Putting the surface inside the de-ionized would stop further reactions.

The advantage of this process is that it gives a wide variety of colors. The colors appear almost as desired, but they fade over time. It is because they are not ultra-violet resistant.

What is the standard size of an aluminum keyboard?

anodized aluminum keyboard size

Keyboard cases come in different sizes. For instance, the aluminum keyboard comes in the following sizes:

Full-Size or 100%

This type of keyboard case carries all the required keys. It is the standard size with all the keys on it. The standard-sized keyboard could have up to 108 tickets. As technology gained popularity, there was a need for smaller keyboards. Therefore, it gave rise to smaller sizes with lesser resolutions.


The 1800-compact has duplicate keys as the standard. The difference is that the keys occupy lesser space.

Tenkeyless (80%, 87%, TKL)

This type of aluminum keyboard carries the standard’s exact size. The difference lies in the omission of the number keypads. Without the number keypads, this type of keyboard would have about 87 or 88 keys.

75% Size

The 75%-sized keyboard carries all the necessary keys with the “F” keys at the top. The chief difference between this size and the TKL is space reduction.

60% Size

The 60% aluminum keyboard case is now typical. It is because it is more compact. It does not carry the number keypads and the “F” keys.

40% Size

It is a minor aluminum keyboard case. The 40%-sized keyboard only contains letters without the numbers.

Here is a comparison table you can know their features quickly:

Different keyboard size features

Will the aluminum keyboard case affect the WIFI signal?

The Aluminum will interfere with wifi signals. Recall that Aluminum is a metal and conductor of electricity. However, the interference is minor. As with all metals, interference is inevitable. Nevertheless, you can improve the wifi signal considerably. Since the interference is petite, you can change the position of your router. Perhaps, you can use aluminum foil to enhance the wifi strength.

Keyboard case comparison: Aluminum VS other materials

Have you seen a comparison for this before?

It’s expedient to have a rich understanding of how these elements comparingly relate to one another so we don’t mistake one for the other. Issues like this cause a lot of stirs on tech enthusiasts and it leads to confusion problems. So, having a sound understanding of how they distinctly function will prevent future stress.

Below is a concise comparison, and it’ll expose inherent disparities that’ll help you discern whichever aluminum case is best for you. Below is a table showing the comparisons.
