The answer to what makes the Keychron K7 remarkably durable in such an ultra-slim body is its premium materials.
Since the beginning of the K7 creation process, we knew it’ll be a tough challenge. We did endless research until we found the aircraft-grade 5052 aluminum alloy enclosure design and implemented it as a pillar of the K7 to make it strong enough to withstand strenuous use and retain its elegantly slim frame.
Crafted with a refined anodized matte surface, the 5052 aluminum alloy on the K7 is considered to have good weldability and resistance to corrosion.

An SGCC galvanized steel plate is added to the plastic bottom frame in order to strengthen the K7's body structure, while still maintaining a stable wireless transmission capability of the K7.

Thanks to the ergonomic support from the adjustable rubber feet and curved profile keycaps, the K7 makes typing on a thin keyboard comfortable and enjoyable.
