6Ni-12Co Maraging Steel

metal

6Ni-12Co Maraging Steel is a precipitation-hardened iron-nickel alloy strengthened by cobalt, molybdenum, and vanadium intermetallic phases, representing a high-strength variant within the maraging steel family. This alloy is used in aerospace and defense applications where exceptional strength-to-weight ratios and damage tolerance are critical, including landing gear, missile casings, and structural components in high-performance aircraft. Engineers select maraging steels over conventional high-strength steels when lightweight designs with superior fracture toughness and dimensional stability are required, and this cobalt-rich composition pushes the upper strength envelope while maintaining acceptable ductility for structural reliability.

Industry-Specific

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.
