MP159 STA Cold Drawn
VerifiedmetalMP159 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.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
