Which is better? Brass or Aluminum Plate Keyboard

We all know that brass plates are more expensive than aluminum plates, but does that make them the best in the market? Honestly, it comes down to how you prefer your mechanical keyboard. If you want your keyboard to have a smooth feel and a low-pitched sound, then a brass plate is the way to go. Whereas an aluminum plate has a tactile feel and produces a high-pitched sound.

Aluminum plates also offer a few advantages compared to brass plates. Aluminum plates are lighter than brass plates, hence easy to carry. Aluminum plates also have a corrosion-resistant finish making them very durable. As aluminum has a low expansion point, this means that it will expand less with temperature changes as compared to brass plates.

While brass plates might have some negatives, they also offer a few perks that outshine aluminum. Brass plates are known for their smooth feel and echoing sound, while aluminum plates are much sharp with a tactile feel. Brass plates might be heavy to carry around, but that makes them more sturdy and resist signs of wear better.

While I was building my pc a couple of years ago, I was too very confused between these two. But I opted over the Brass plate as I wanted something smooth and lightweight.

Points To Consider If You Are Getting Confused Between Brass & Aluminum Keyboards

Sound and Feel

Switches are not the only things that make a mechanical keyboard sound and feel different from one another. Plates are the very foundation that switches are laid on that make a huge difference. 

As brass plates are denser than aluminum plates, they produce a low-pitched deeper sound known for their echo and soft feel. As the aluminum plates are light, they make a much more high-pitched sound known for their clicky sound.


As the brass material is heavier than aluminum, they are more troublesome to travel with and move around while in use. As aluminum plates are lighter, they are easy to carry. Thus, aluminum plates are more portable and light in weight.


Brass plates are more durable than aluminum plates as they are more dense and sturdy. Aluminum plates are more flexible and are more prone to damage. Although, brass plates do not have a corrosion-resistance layer and thus oxidize over time.

Brass plates are more rigid than aluminum plates making them resist tear and wear better. Aluminum plates also have a layer of corrosion-resistance layer, thus making them corrode slowly.


Aluminum plates are cheaper than brass plates. Hence, making them much more cost-effective. As brass plates offer a unique experience with higher durability, which makes them worth the price difference.

Many people prefer aluminum plates as they are cost-effective. Although many keyboard enthusiasts say,” it is worth the extra $30-$50”.


Brass plates are not corrosion-resistant and thus produce a thin layer of oxidation over the surface. This oxidation makes them look discolored and dull. However, it is easy to clean off without damaging the keyboard. Aluminum plates have a corrosion-resistant layer which prevents any oxidized layer from developing.

Scratch Resistant

As aluminum material is much softer than brass, it is more prone to scratches. Brass is a rigid material and thus is less likely to get a scratch on its surface.

How do Brass and Aluminum Plates Interact with Different Switches?

Now we know about the individual qualities of brass and aluminum plates, so let’s talk about how they interact with different switches. As we all know, that switches are one of the most crucial factors behind the sound and feel of a keyboard. 

While buying a custom plate, you should know how it interacts with different switch types. Here are some of the most popular keyboard switches and how brass and aluminum plates interact differently with them.

Clicky Switches

Aluminum plates are less dense than brass plates allowing them to produce bright and sharp sounds. Although, the clicks would feel more stable and well-rested in brass plates. 

Tactile Switches

Tactile switches are well known for their feedback and are prevalent in gaming keyboards. Brass plates provide a solid and rigid foundation for tactile switches. 

This solid foundation helps amplify the synaptic feedback making them a better pair for brass plates. Aluminum plates also work decently with tactile switches, as they are firm and very durable.

Linear Switches

Linear switches are one of the most common switches available in the market. They are well known for their loud sound. Both brass and aluminum plates pair up well with linear switches. 

Aluminum plates are high-pitched and amplify the loud keystroke sound produced by the linear switches. Brass plates offer a little more stability but are equally loud when laid with linear switches. 

Different Types of Metal Plate Keyboards

Customizing a keyboard really comes down to personal preference. There are various other metal plates that you should know about before making the final purchase. Here are some of the metal plates available in the market.
