    Description

    The 90−10 alloy PLI is used: for the manufacture of semi-finished products (sheets, tapes, strips, foils, wire, pipes, profiles, forgings) by hot or cold deformation used in instrument and apparatus building; and discontinuous sliding contacts; medical supplies; jewellery for personal adornment (necklaces, narrow and wide bracelets, original hair accessories, filigree earrings, brooches, pendants, wedding rings, rings, chains).

    Note

    Platinum-iridium alloy.
