CoCr (L-PBF, EOS CobaltChrome MP1, heat-treated)

EOS CobaltChrome MP1 is a cobalt-chromium-molybdenum powder grade processed by laser powder bed fusion, here in the heat-treated condition. As built, it has a very fine cellular solidification structure, largely metastable face-centred cubic, with high residual stress and some anisotropy between build directions. Heat treatment, usually done before parts are cut from the build plate, relieves these stresses and homogenizes the microstructure, limiting distortion and directional differences. Supports must still be removed and functional surfaces machined or polished. Typical uses are dental frameworks, implant-type components and wear- or heat-resistant engine parts. Every value on this page is read from EOS's own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
