    Abstract: A component for an electronic device can include a metal injection molded (MIM) metallic body that at least partially defines an exterior surface. The metallic body can have an average porosity less than 1% in a first region that extends from the external surface to a depth of at least 100 microns below the external surface, and an average porosity greater than 1% in a second region adjacent to the first region.

    CPC classification number: C22C45/10 ,  C22C1/002

    Abstract: The disclosure is directed to Zr and Hf bearing alloys that are capable of forming a metallic glass, and more particularly metallic glass rods with diameters at least 1 mm and as large as 5 mm or larger. The disclosure is further directed to Zr and Hf bearing alloys that demonstrate a favorable combination of glass forming ability, strength, toughness, bending ductility, and/or corrosion resistance.

    Abstract: The disclosure is directed to aluminum alloys made from recycled components. The alloys have copper (Cu) from 0.051 to 0.10 wt %, chromium (Cr) from 0.01 to 0.10 wt %, zinc (Zn) from 0.02 to 0.20 wt %, manganese (Mn) from 0.03 to 0.10 wt %, iron (Fe) in an amount of at least 0.10 wt %, silicon (Si) in an amount of at least 0.35 wt %, magnesium (Mg) in amount of at least 0.45 wt %, and the remaining wt % being Al and incidental impurities. In other aspects, the disclosure is directed to aluminum alloys having copper (Cu) from 0.010 to 0.050 wt %, chromium (Cr) from 0.01 to 0.10 wt %, zinc (Zn) from 0.01 to 0.20 wt %, manganese (Mn) from 0.03 to 0.10 wt %, iron (Fe) in an amount of at least 0.10 wt %, silicon (Si) in an amount of at least 0.35 wt %, magnesium (Mg) in amount of at least 0.45 wt %, and the remaining wt % being Al and incidental impurities. The b* color of the alloys ranges from −2 to 2, and the L* color ranges from 70 to 100.
