VMT 2026 07 15 Aluminum is widely used for custom mechanical keyboard cases because it balances low weight, rigidity, CNC machinability, corrosion resistance, and anodized appearance. For most projects, 6061 is the practical starting point, 6063 suits appearance-focused designs, and 7075 is reserved for applications that genuinely need higher strength. This guide explains why aluminum is popular for mechanical keyboard housings, how the main alloy grades differ, and what you should confirm before choosing a material for your project.
