MP159

Verifiedmetal

MP159 is a cobalt-based superalloy containing nickel, chromium, and molybdenum, designed for high-temperature aerospace applications requiring excellent fatigue strength and corrosion resistance up to approximately 700°C. The STA (solution-treated and aged) cold-drawn condition provides enhanced tensile strength and fatigue performance through precipitation hardening, making it suitable for engine components, fasteners, and structural elements in military aircraft and gas turbine applications.

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.
