Jis B 0419-mk Instant

Standard sintered iron parts can sometimes be brittle or porous. By infiltrating with copper, the MK designation provides a substantial boost in hardness. The copper acts as a reinforcement within the steel lattice. Typical tensile strengths for MK materials can range significantly depending on the carbon content and density, often outperforming non-infiltrated Fe-Cu-C mixes.
