Material selection affects the airsoft gearbox's durability, weight, and suitability for high-performance builds. High-grade aluminum alloys (like aircraft dural EN AW 7075) offer an excellent balance of strength and lightness, while cheaper zinc or pot metal shells may be more affordable but less robust. Steel reinforcements are also valued in critical stress points. The RETRO Arms CNC Split Gearbox V2 uses EN AW 7075, which has steel-like strength with aluminum's lightness—ideal for demanding setups. The availability of different materials allows users to prioritize either cost, weight, or strength according to their needs.
