Stainless steel figure-8 descenders are far more wear-resistant than aluminum, making them ideal for frequent use, heavy loads, or gritty rope conditions where grooving happens quickly. Aluminum is lighter and dissipates heat faster, but it’s a softer metal, so it will show wear sooner and need replacement more often. In general, choose stainless for durability and long service life, and aluminum when weight and cooling matter more.
