MP159 is a nickel-cobalt-base superalloy containing chromium, molybdenum, and tungsten, designed for high-strength fastener and spring applications in aerospace engines and structures. The STA (Solution Treated and Aged) cold-drawn condition provides superior tensile strength and yield strength with controlled ductility, maintaining excellent fatigue resistance and stress-rupture performance at elevated temperatures up to approximately 700°C.
