When building or buying a mechanical keyboard, the materials used for the case and plate are often overlooked—but they’re critical to shaping your overall experience. These components don’t just hold your keyboard together; they dictate how it sounds, feels, and performs, whether you’re gaming at high speeds, typing for hours, or showing off a custom build.

How Materials Impact Sound & Feel

The materials in a keyboard’s case and plate act as the foundation for two critical aspects of your experience: sound and typing feel, both of which can transform a mundane typing session into a tactile and auditory delight—or frustration.

Sound: From Resonance to Tone

The case material dictates how sound waves resonate. Rigid materials like aluminum or steel amplify sharp, high-frequency tones, creating a crisp, “clicky” clatter that enthusiasts associate with mechanical keyboards. In contrast, softer materials such as plastic, wood, or polycarbonate absorb vibrations, producing muted, bass-heavy sounds that are gentler on the ears—ideal for quiet environments or those seeking a more understated best mechanical keyboard.. The plate, meanwhile, influences the “core” switch sound: stiffer plates transfer more energy, enhancing the metallic ring of each keypress, while flexible plates muffle harsh edges, delivering a warm, “thocky” tone loved for its smoothness.

Feel: Stability Meets Feedback

Typing feel hinges on rigidity vs. flexibility. A solid aluminum case provides rock-solid stability, critical for gamers who need precise, wobble-free keystrokes during intense gameplay. Lighter plastic or acrylic cases, however, offer subtle flex, which some find more comfortable for marathon typing sessions by reducing finger fatigue. The plate’s flexibility also plays a role: stiff plates (like brass) offer direct, tactile feedback, perfect for tactile switches that emphasize each bump of key travel, while flexible plates (such as polycarbonate) create a springy, which some find more comfortable for marathon typing sessions by reducing finger fatigue, making them a versatile choice for a best gaming keyboards.

Case and Plate Materials: A Detailed Look

Aluminum

Aluminum is the gold standard for premium mechanical keyboard cases, favored for its rigidity, lightweight strength, and sleek aesthetic. It offers excellent heat dissipation, making it ideal for long gaming sessions where sustained performance matters. The solid build minimizes flex or wobble, providing a stable base that feels “locked in” during fast typing or intense gaming. Its natural metallic finish lends a high-end look, while anodized coatings allow for vibrant colors without compromising durability. However, aluminum cases can be pricier and may produce a sharp, resonant “ting” when struck—great for those who love a crisp sound profile but less so for quiet environments.

Plastic (ABS/POM)

Plastic cases, typically made from ABS (Acrylonitrile Butadiene Styrene) or POM (Polyoxymethylene), are the go-to for budget-friendly and lightweight designs. ABS is highly customizable, supporting bold colors and intricate shapes, while POM offers superior resistance to wear and a smoother surface finish. These materials are perfect for portable keyboards or entry-level models, as they keep weight low without sacrificing basic durability. However, they lack the rigidity of metal, which can lead to subtle flex in cheaper builds, and ABS may yellow over time with prolonged use. Still, these materials are perfect for portable keyboards, making them a practical choice for gamers seeking a best mechanical keyboard on a budget.

Wood

Wooden cases bring a touch of natural elegance and warmth to mechanical keyboards, appealing to designers, typists, and anyone seeking a unique aesthetic. Crafted from materials like walnut, maple, or bamboo, these cases offer a one-of-a-kind grain pattern that no two keyboards share. Wood is surprisingly durable when sealed properly, though it requires occasional maintenance to prevent warping or water damage. The sound profile is muted and warm, reducing harsh echoes—a plus for office environments—while the tactile feel is smooth and organic. However, wooden cases are often handcrafted, making them premium-priced and less common in mass-market gaming keyboards.

Acrylic/Polycarbonate

Acrylic and polycarbonate (PC) are all about transparency and flexibility. These materials excel at showcasing RGB lighting setups, as their translucent properties evenly diffuse LED colors for a stunning visual effect. PC, in particular, is more impact-resistant than acrylic, making it a smarter choice for cases that need both durability and style. While they lack the rigidity of metal, their slight flex can soften the typing feel, producing a deep, “thocky” sound loved by enthusiasts. 

Steel

Steel cases are the ultimate choice for extreme durability and industrial toughness. They’re virtually indestructible, resisting dents, scratches, and heavy impacts—ideal for professional settings or users who demand a keyboard that lasts a lifetime. The weight of steel adds a planted, stable feel, though it sacrifices portability (expect a keyboard that weighs over 2kg). The sound profile is sharp and resonant, amplifying the click of mechanical switches for a bold, tactile experience. However, steel is costly, heavy, and limited in design compared to lighter materials, making it a niche choice for enthusiasts who prioritize ruggedness over all else.
