While still continuing with a proprietary alloy, we have found that these pistons outperform many of their Aluminum 4032 competitors in the market. Comparing the two side by side, they both have very similar Elongation (%), Yield strength (kg/mm2), and Tensile Strength (Kg/mm2), But Namura's Forged pistons hold an expansion rate that is actually lower than 4032 forged aluminum. Giving you longer lasting build tolerances than our competitors
