Keyboards whose body or certain elements are made of metal. This can be either the entire body or its parts - for example, a metal plate as a base for keys. Note that when it comes to the metal construction of the keyboard, the latter option is more common.

Compared to plastic—the most common keyboard case material—metal is much stronger, more durable, and more durable. It has a significant weight, but in this case it can also be written down as advantages — massiveness contributes to stability and reduces the likelihood that the keyboard will "fidget" under the fingers. In addition, metal cases look stylish and solid. On the other hand, they are noticeably more expensive than plastic ones, and the advantages mentioned are not so much practical as psychological. Therefore, this feature is found mainly in advanced gaming models (see "By Direction"), for which a solid appearance is no less important than functionality.
