Aluminum is vulnerable to damage due to its flexibility, but a brass keyboard plate is almost impossible to damage, even after constant use.

Brass is the ideal option to choose if you want to guarantee that your keyboard will survive for a long time.


Aluminum keyboard plates have a more flexible feel than brass ones. Even if you are an expert in typing, you’ll notice that the feedback is much stiffer once a key has bottomed out on a steel plate compared to a plastic plate.

If you prefer a lighter keyboard and a more fantastic range of motion, allowing you to type more quickly, then aluminum plates are going to be a better option for you compared to brass plates.

As for sound, brass keyboard plates generate a deeper, lower-pitched sound than aluminum keyboard plates, making keypresses on brass plates seem more satisfying than on the aluminum plate keyboard.


Brass keyboard plates are somewhat less comfortable than aluminum plates because of the risk of tarnishing. On the other hand, aluminum keyboard plates need no maintenance at all.

Even though tarnishing will not significantly affect your experience, it will need to be cleaned and maintained regularly to ensure that it remains in excellent condition.


While the aluminum plate is a material of choice for most keyboards because of its low cost, a brass plate may cost as much as $20-30 or more than an aluminum plate due to the higher cost of the brass material itself.

Despite the higher cost of brass plates, some prefer the harsh and high-pitched sound along with the rigid and tactile switches that come along with it.

On the other hand, aluminum plates are inexpensive and more affordable despite their popularity. Since it’s both strong and lightweight, affordability is an added bonus when you choose an aluminum plate.
