Material choice greatly impacts the durability, performance, and longevity of your aeg internals. The best materials depend on the part's function—high-stress components like gears or pistons often benefit from steel or fiber-reinforced polymers, while lightweight yet strong alloys like aircraft-grade aluminum (EN AW 7075) are ideal for gearboxes. High-grade polymers and reinforced plastics are also common for tappet plates and pistons, balancing strength and cost. For instance, the RETRO Arms CNC Split Gearbox V2 uses aircraft dural EN AW 7075 for exceptional strength-to-weight, while the RETRO Arms - Piston (14.5 Steel Teeth) features a carbon fiber-reinforced PA 6.6 body with CNC steel teeth for maximum resilience. The SHS - Lightened Fiber Reinforced Polymer Piston (15 Teeth) offers a fiber-reinforced polymer body, ideal for lighter setups. There are many material options available to suit different upgrade needs and budgets.
