Abstract (en)
[origin: EP0520465A1] This invention comprises a sintered alloy of a nitride of titanium or a carbonitride of titanium and metals having vivid gold color, being excellent in strength, hardness and anticorrosiveness as well as facilitating for a sharp edge working, wherein titanium is contained in an amount of 55 to 75% by weight with respect to the whole amount, metals of the iron family and elements of the Group 6a of periodic table including at least chromium are contained in an amount of 3 to 30% by weight with respect to the whole amount, and the remainder being non-metallic elements consisting of nitrogen or nitrogen and carbon, and wherein the ratio of carbon with respect to said non-metallic elements is smaller than 10% by weight, and the ratio of chromium in the metal elements excluding titanium is not smaller than 35% by weight.
